Introduction
Safety information
Intended use
The ApexPro Telemetry System is intended for use under the direct supervision of
a licensed healthcare practitioner. The system is designed to acquire and monitor
physiological data for ambulating adult and pediatric patients within a defined
coverage area. The system processes this physiological data to detect various
ECG arrhythmia events and select physiological parameter limit violations.
The ApexPro Telemetry System is intended to be installed in the hospital or clinical

environment in order to provide clinicians with patient physiological data, while
allowing for patient mobility. These systems are typically deployed in sub acute
care areas in hospitals or clinical sites where patient mobility can enhance the

Equipment Overview
System overview
Overview
A transmitter is directly connected to the patient and transmits monitored data
via the antenna to a corresponding receiver in a one-to-one correspondence
between transmitters and receivers. Up to 16 receivers (four quad receiver
modules with four receivers on each) may reside in a receiver system. Up to four
quad receiver modules connect to the receiver backplane PCB, which is
responsible for managing communications between all connected receivers and
the telemetry host application software on the PC. The communication between
the PC and the receiver backplane is 10BaseT Ethernet and is called the Receiver-
Exchange (RX) network. The host application software processes the patient data
from the receivers and makes the patient’s ECG parameter and waveform data
available for display at network viewing stations or the Clinical Information Center
(CIC) central station.

Power requirements
The DC power requirements for the ApexPro antenna system depend greatly on
the configuration of each individual system. To ease the power requirements of
the ApexPro telemetry system, the power supply for the antenna system is
external to the ApexPro receiver system and separate from the antenna.
Interface with ApexPro receiver subsystem

Each receiver in the quad receiver module, located in the receiver subsystem,
receives data from the transmitters. This data is processed by the receiver system
and then transmitted via the dedicated Ethernet interface to a CIC Pro center for
further processing and display. The quad receivers and the receiver subsystem
together are known as the receiver system.
The interface between the antennas and the receiver system consists of coaxial
cabling and connectors for transferring the transmitted signal. The interface uses
75-ohm cable from each antenna field and F style 75-ohm connectors as a
connection medium. The preferred cable is RG-6, but for longer lengths RG-11
may be used.
Interface with multiple ApexPro receiver subsystems

To interface the antenna system with multiple ApexPro receiver systems, each
antenna field in the antenna system is split into the appropriate number of tap
points using combiners/splitters before connecting to each ApexPro receiver
system.

CARESCAPE Network
NOTE
The Unity Network has been renamed to the CARESCAPE Network. Not all
references to the Unity Network will be changed immediately; Unity may
appear in some places and CARESCAPE in others. It is important to
understand that while the CARESCAPE Network replaces the Unity Network
name, they refer to the same GE monitoring network.
The CARESCAPE Network is the networking system used to transmit information

from one GE product to others connected to the same CARESCAPE Network.
ApexPro antenna system

Antenna
The antenna system is used for transmission of data from the transmitter to the
receiver system.
The antenna is a circularly-polarized array of sloping half-wave dipoles with an

omni-directional coverage pattern. The antenna is available in two versions:
active and passive. An active antenna includes an active amplifier, while a passive
antenna provides no signal amplification. The receiver antenna comes with a
standard drop ceiling T-bar mount.
Antenna amplifier
The antenna amplifier boosts the signal when losses from other antenna
components exceed the gain of the antenna. DC power for the amplifier is
obtained from the +12VDC power supply.
Coaxial cable
Coaxial cabling is used to connect the omni-directional antennas and amplifiers
to the receiving equipment. Controlled-impedance cabling is used and 75-ohm,
RG-6 type is recommended. Plenum- or riser-rated cable is used to meet NEC fire
codes. RG-11 may be used if cable lengths become long and dB losses become
excessive.
Splitters/combiner
Passive splitters/combiners split or combine the RF signal into multiple paths. The
same splitter may also be used as a combiner to join multiple RF signals into one
path. There are two-, four-, or eight-way splitters available that are DC-passive.

Equipment Overview
Attenuators
Attenuators lower signals and balance antenna runs. The attenuators are DC-
passive and are available as 3 dB, 6 dB and 10 dB attenuators.
Power supply
A +12VDC power supply at 1A supplies power to the antenna system. Power
supplies accept AC voltages between 90-270VAC. AC inputs have internal fuses
that are not replaceable. The output of the supply is short circuit protected.
Bias tee
The antenna bias tee allows the injection of DC power from the antenna power
supply into the antenna system cabling. The bias tee supplies RF isolation
between the RF signals on the antenna cabling and the power supply. It contains
a DC block that blocks the conduction of DC power to the receiver system and
associated hardware. A bias tee is used with each power supply.
Notch filter
Notch filters are frequency or TV channel specific and notch out the TV video,
audio, or digital center of the band signals. Notch filters also filter pager signals or
other strong RF signals that can be found in a telemetry environment.
Bandpass filter
The bandpass filter rejects frequencies outside its listed bandwidth and passes
frequencies inside its listed bandwidth. It is used in place of certain notch filters to
provide wide band filtering with less in-band loss than multiple notch filters.
Identify antennas
Identify the high-power and active antennas by the part number label and the GE
logo only on the front (bottom). The passive antenna looks identical to the high-
power antenna except it has a black cap over the LED power indicator. To visually
identify the antenna type, observe the following:
 The -002, -003, -004, and -005 models have an embossed GE logo.
 The -006, -007, and -008 models have a blue GE logo.
 The -003, -005, and -006 passive antennas have a black cap over the LED
power indicator.
For further identification, check the part number label.

CAUTION
UNINTENTIONAL RADIO FREQUENCY (RF) INTERFERENCE—
Unintentional RF interference could degrade the reliability and
performance of the wireless data link. The facility must maintain
an RF environment free from unintentional interference.
The ApexPro and CARESCAPE transmitters send the patient’s ECG data to the
ApexPro receiver system for processing. Data is then transmitted via a dedicated
Ethernet interface to the CIC Pro center for viewing. The transmitter can also send
DINAMAP PRO data to the CIC Pro center via the DinaLink cable.
Additionally, the transmitter can send the patient’s SpO2 and noninvasive blood
pressure data when the interface connector ports are enabled and when the
optional oximeter and/or Accutracker DX noninvasive blood pressure monitor are
connected to it.

Equipment Overview
Apex oximeter
Theory of operation - pulse oximetry
Pulse oximeters shine light (red and infrared) through perfused tissue and detect
the fluctuating signals caused by arterial blood pressure pulses. Well-oxygenated
blood is bright red, while poorly oxygenated blood is dark red. The pulse oximeter
determines functional oxygen saturation of arterial hemoglobin from this color
difference by measuring the ratio of absorbed red and infrared light as the blood
volume fluctuates with each heart beat. Since steady conditions (steady venous
blood flow, skin thickness, bone, finger nails, etc.) do not cause fluctuations, they
do not affect the saturation reading.
Mathematically:
min
SpO2 = f
(
In max ( red
In min
( ( infrared
max
801
Anything that affects the intensity of the light such as thick or colored skin affects
the maximum and minimum proportionally and thus the ratio minimum/
maximum does not change. However, if too little light gets through, the pulse
oximeter does not function.
Pulse oximeters use two different wavelengths of light (colors) and thus have the
ability to determine one component of blood. Pulse oximeters are calibrated to
closely approximate functional oxygen saturation values. Pulse oximeter oxygen
saturation values will closely approximate laboratory instrument fractional
saturation values if the dysfunctional hemoglobin saturation levels are negligible.
If the dysfunctional hemoglobin is carboxyhemoglobin or methemoglobin, then
the difference between the oxygen saturation value displayed by the Pulse
oximeter and the oxygen saturation values determined by the laboratory
instrument are greater as the dysfunctional hemoglobin levels rise approximately
in accordance with the following formulas:
 SpO2 = O2Hb + COHb + MetHb

 SaO2 = 100 x O2Hb /(100 - COHb - MetHb)
Where:
 SpO2 = Pulse oximeter determined and displayed oxygen saturation in

percent
 O2Hb = Fractional oxyhemoglobin saturation in percent
 COHb = Carboxyhemoglobin saturation in percent
 MetHb = Methemoglobin saturation in percent
 SaO2 = Functional oxygen saturation in percent
The following table gives examples of the oximeter readings:

Equipment Overview
Example 1 Example 2
O2Hb = 96 O2Hb = 88
COHb = 0.5 COHb = 8
MetHb = 0.6 MetHb = 2
SpO2 = 97 SpO2 = 98
SaO2 = 97.07 SaO2 = 97.78
The mathematics are fixed in the pulse oximeter hardware and software. Thus, no
field calibrations are needed or are possible. There are no adjustable parts within
the pulse oximeter that affect the calibration.
The function f, depends on the wavelengths of the sensor LEDs. These

wavelengths are fixed by specified manufacturing processes and materials. The
sensors are checked for correct operation before shipping, so no adjustment or
calibration is needed or possible.
Because the pulse oximeter does all critical computations in software and there
are no critical parts to drift; no re-calibration is needed.

ApexPro receiver system

Overview
The Receiver System receives RF signals from the four antenna inputs. These
inputs are for four separate, overlapping fields. The system performs the following
functions:
 filters RF (backplane)
 distributes RF to quad receiver modules (backplane)
 demodulates and decodes transmitter data (quad receiver modules)
 retrieves decoded data (backplane)
 packetizes and sends data out over RX network (backplane)
The asynchronous serial communication port is for diagnostics, service and

installation information.
The RX network is directly connected by a network crossover cable to an ApexPro

Telemetry System. The RX network should not be tied to any other network.

Equipment Overview
rcrsysblk
Receiver System Block Diagram
Receiver subsystem (backplane)

The subsystem provides an interface between the quad receiver modules and the
telemetry software running on the ApexPro Telemetry System connected via
10BaseT Ethernet. The subsystem accommodates up to four quad receiver
modules. The subsystem performs the initial amplification and filtering necessary
on the RF input signals from the transmitter.
Quad receiver modules

The quad receiver module receives the GMSK modulated RF signals from the
transmitter through the receiver subsystem (backplane). The RF signals are mixed
to an intermediate frequency, filtered, and mixed again to baseband and re-
filtered. The baseband signal is separated into its in-phase and quadrature
components then sampled. The DSP takes the samples, demodulates, corrects,
and decodes packets of TLINK data. The information is passed on to the receiver
subsystem for further processing and transport over Ethernet. Each module has
four functionally identical receivers.

This chapter provides direction for how to install specific parts and gives
guidelines for specific tools to use for installation.
Install coaxial cable

Installation guidelines
Use the hospital scaled prints and the logical antenna schematic to install the
cabling. The logical antenna schematic is generated by ND&I.
Keep the following in mind when installing coax cable.

 Always follow the National Electric Code regulations.
 Always use PVC for the feed-throughs.
 Do not kink the cable. If the cable is kinked, cut out the kinked part and
reattach.
 Do not pull cable over any metal edges or other abrasive surfaces.
 Do not pull cable for one room at a time. The entire cable spool should be
accessible and multiple runs should be pulled at the same time into the
ceiling.
 Do not lay cable on top of light fixtures.
 Lay out cable uniformly and with excess slack. The slack should consist of
about 25 cm (1 foot) or so every 3 m (10 feet), both horizontally and vertically.
 Do not coil up any extra cable, but instead increase the amount of excess
slack throughout the entire length of cable.

solid copper or copper-clad aluminum wire.
2 Dielectric — An electrical insulation utilized to maintain position of the

center conductor. It is composed of polyethylene in either solid or foam
state. This insulator/positioner may also be evenly spaced solid
polyethylene discs.
3 Outer conductor or foil — Either solid aluminum tube or an aluminum foil

wrap. The cable size is usually derived from its outside diameter.
4 Braid — Interwoven strands of aluminum or copper mesh. It extends the

conductivity of the outer conductor to the sleeve of the connector.
5 Jacket — The black polyethylene coating over the aluminum outer

conductor protects it from scratches or abrasions during handling and
provides a weather-tight seal. The jacket on plenum cable is made of
teflon specified by fire codes.

Install antennas
NOTE
Be sure that after planning and designing the antenna system, the
Penetration Check test (described in the ApexPro Antenna System Installation
Test Instructions) is completed. It is used to estimate the RF penetration of the
hospital construction.
The standard installation for antennas uses a T-bar mount connected to the drop
ceiling support. The retaining clip and pin come with the antenna.
For ceiling tile or dry wall mounting, see “Optional antenna mounting kits” on
page 6-3 to order additional hardware kits necessary for these mounting options.
All antenna mounting installation options and instructions are described in the

ApexPro receiver installation

Due to the fact that frequency drift occurs even without power applied, the
calibration schedule should take into account the date the equipment was last
calibrated, including equipment in storage locations and spares.
Before installing in the United States, determine and record the date of initial
factory calibration of receivers from the removable calibration sticker that ships
on these devices. If installation does not occur within 30 months of the date
shown on the manufacturer calibration sticker, calibrate before installing, and
every 24 months thereafter. See Calibration on page 4-32.
All receivers installed outside of the United States must be calibrated 24 months
after initial receipt of the unit, and every 24 months thereafter. See Calibration on
page 4-32.
Mounting options
The mounting options for the ApexPro Telemetry System Receiver System are:
 Standard tabletop mount (four rubber feet)
 Optional rack mount for standard 19 inch network rack system with a 4U
panel height (177.8mm/7in.). (Order rack mounting kit #2004232-001
separately.)

Transmitter installation
Before installation, determine and record the date of initial factory calibration of
all T14 transmitters. The date of initial factory calibration of T14 transmitters can
be determined from the removable calibration sticker that ships on these devices.
After determining the date of initial factory calibration for each T14 transmitter,
calibrate each T14 transmitter within 30 months of its initial factory calibration or
24 months after installation, whichever occurs first, and every 24 months
thereafter.
For all other transmitters (that is, non-T14 transmitters), calibrate each transmitter
24 months after initial receipt, and every 24 months thereafter.
For additional information see “Calibration” on page 4-32.
Programming the transmitter for use

Before use, the transmitter must be programmed. The transmitter is programmed
or upgraded in the field to:
 select the operating frequency and corresponding TTX number
 select the reference lead
 set the alarm pause time
 select the filter setting
 change the serial number
 download new software
Refer to the ApexPro Telemetry Frequency Chart Reference Manual for the
operating frequencies and the corresponding TTX ID numbers.
Refer to the Transmitter Programming Box Programming Instructions for details.
2001989-469A ApexPro 3-19

Transmitter configuration
Program code storage
Executable program code for the main processor is stored in non-volatile
programmable memory. Program code can be changed via an interface
connector port using the PC-based programming box software or a
HyperTerminal program and a programming box. The version of the currently
stored transmitter code can be displayed using the transmitter programming box
software kit. See the Transmitter Programming Box Programming Instructions.
Error log
The transmitter contains an error log in its non-volatile programmable memory.
When a synthesizer lock error occurs, this is logged and latched into the
appropriate memory space. When a checksum error on start-up occurs, this is
logged into the appropriate memory space for this as well. The error log can be
viewed using the programming box PC software or a HyperTerminal program.
This reports both of these errors as well as a real-time report of the synthesizer
lock status.
Parameters
Using the ApexPro programming box software, certain transmitter parameters
can be viewed and some can be changed while in service mode.

Antenna system verification tests

Out-of-band RF signal test
Rationale for test
The Out-of-Band RF Signal Test checks for signals that may overload the receiver
subsystem and receivers. It indicates if there are any out-of-band (above the
display marker line) signals that must be properly attenuated by the antenna
system.
Equipment needed
NOTE
The steps in this procedure are based on the use of the Rohde & Schwarz
FSH3 spectrum analyzer. If a different spectrum analyzer is being used, the
detailed substeps may be different.
 Spectrum analyzer
 N-connector-to-BNC-connector adapter
 BNC-connector-to-F-connector adapter
 Cable with F-connectors on both ends to connect the antenna system output
to the spectrum analyzer input
NOTE
This cable should be less than 6.1 m (20 ft) long.
Test procedure
For each antenna field, perform the following test.
1. At the main board, connect the spectrum analyzer to one of the ports on the
splitter that feeds the ApexPro receiver subsystems for the field under test.

Unity signal gain test with transmitter

Rationale for test
This test verifies unity gain for each antenna run to ensure that each antenna is
operating as designed.
Equipment needed

2001989-469A ApexPro 4-13

Maintenance
 Cable with F-connectors on both ends, to connect the antenna system output
NOTE
 Transmitter
 Transmitter programming box and ApexPro programming box software
Technical information
The purpose of this test is to verify proper gain for each antenna using a peak-
hold test for each antenna. For each antenna in the antenna system, the signal
level should be -50 dBm ±5 dB for a unity gain signal balance design and -40 dBm
±5 dB for a +10 dB gain balance design, as measured at the receiver system.
NOTE
This test should not be used to balance the antenna system. The accuracy of
this test due to variation in transmitter output power, path loss, multi-path
fading, etc., results in this test having a variability of 10dB or more. Rather, this
test is intended to reveal major issues in your system.
Test procedure
Transmitter setup
1. Program a known good transmitter to an unused frequency close to the
frequency of the transmitters used in the hospital.
See the Transmitter Programming Box Programming Instructions for steps
needed to program the transmitter.
Alternatively, you can borrow one of the hospital’s transmitters.
2. Connect a shorted-lead set to the transmitter. Otherwise, each time you turn
the transmitter on you need to set the transmitter into Pause Alarm mode.

Example of a failing unity signal gain test with transmitter

This example shows the gain through the antenna run to the main closet. In this
case, however, the signal level is -59.84, which is below the tolerance level of
-50 dBm ±5 dB, so the measurement fails the Unity Signal Gain Test with
Transmitter. This indicates the antenna or antenna run is faulty and must go

Noise floor performance test

Rationale for test
The noise floor affects the ability of the receiver to detect weak transmitter
signals. Lower noise floors improve the ability of the receiver to detect weak
signals. ApexPro receivers require that the peak of the transmitted signal is at
least 10 dB above the measured noise floor. To take advantage of the full
dynamic range and sensitivity of the receiver, the noise floor should be 10 dB
below the sensitivity of the receiver. To take full advantage of the specified
receiver sensitivity of -90 dBm, the noise floor should be -100 dBm or lower as
measured by this test.
NOTE
The lower the number of antennas on a given field, the lower the noise floor
should be. A system should only approach a noise floor of -100 dBm if it is
approaching or exceeding approximately 300k square feet of total coverage.
In addition to the sensitivity of the receiver, this test will also indicate if one of the
active components in the antenna system is overloaded. Active devices such as
in-line amplifiers can be overloaded when the input signals are too strong. When
the devices are overloaded, they produce more noise, which raises the noise floor
of the entire field that they are attached to. This can happen when there is too
much gain in the antenna system causing transmitter signals to be too strong, or
when strong TV stations are present in the area. To mitigate against these
possibilities, the antenna system is designed to have unity gain, 0 dB ± 3 dB by
design, before each active component, and filters are used for TV stations. This
means that the signal that is present at the antenna is also present as an input to
each active device unless filtered.

of coverage each antenna provides. This test verifies that the antennas are
providing adequate coverage in the antenna system coverage area. This test is
done after the antenna system has been assembled and the gain for each
antenna has been tested. It essentially repeats the penetration checks that were

The purpose of the In-band Noise Test is to scan the frequency spectrum selected
for telemetry use to locate any noise sources and to exclude these frequencies for
selection as transmitter frequencies. If transmitters are chosen to operate on
frequencies that also contain sources of noise, the noise can potentially cause
interference to the transmitter, resulting in RF drop-out for the interfered

Acceptance criteria
Any signal level above –95 dBm will require the TTX number most closely
matching the frequency of the signal level to be unusable for telemetry

Transmitter Frequency Validation

Rationale for test
The purpose of this test is to verify that transmitter frequencies are valid for the
notch filters used. TTX numbers in the 2 MHz adjacent to a notch filter channel can
NOT be used by ApexPro CH transmitters. Program ApexPro CH transmitters to
frequencies furthest from the notch filter frequencies.
If a notch filter is used that is one channel above the channel occupied by the
ApexPro Telemetry System, then the top two megahertz can not be used by
transmitters. For example, if the ApexPro Telemetry System occupies channel 37
(608 - 614 MHz) and a notch filter is required on channel 38, then only 608 - 612
MHz should be used by transmitters. Begin programming transmitters from the
lowest frequencies in channel 37 first.
If a notch filter is used that is one channel below the channel occupied by the
ApexPro Telemetry System, then the bottom two megahertz can not be used by
transmitters. For example, if the ApexPro Telemetry System occupies channel 37
and a notch filter is required on channel 36, then only 610 - 614 MHz should be
used by transmitters. Begin programming transmitters from the highest
frequencies in channel 37 first.
NOTE
ApexPro transmitters do not support TTX numbers below 7560 (Ch 32 and
lower) or above 8760 (Ch 38 and higher.) ApexPro CH transmitters do not
support TTX numbers below 8520 (Ch 36 and lower) or above 8760 (Ch 38 and
higher).
This test is designed for the United States only. For sites outside of the United
States, contact ND&I with a list of frequencies and signal levels for the noise
sources that need filtering.
TTX and frequency restrictions

If a Ch 36 notch filter is being used, there must be no transmitters occupying 600 -
602 MHz (TTX numbers 8200 through 8280) or 608 - 610 MHz (TTX numbers 8520
through 8600).
If a Ch 38 notch filter is being used, there must be no transmitters occupying 612 -

614 MHz (TTX numbers 8680 through 8760).

System troubleshooting
RF drop-out determination
Turn on drop-out flags on the CIC Pro to check the color of any drop-out on the
patient signal lead waveform at the CIC Pro patient view.
1. From the main CIC Pro screen, select the Setup CIC button.
2. Select the Service Password tab.
3. Type the password mms_com and then select OK. A Command prompt
window is displayed.
4. Type setflags<Space>-mark<Space>all and press Enter on the keyboard to
turn on drop-out flags.
 If the color is yellow, suspect RF drop-out on the transmitter, the antenna
system or the receiver system.
 If the color is light blue or dark blue, suspect a network issue, not an RF-
related drop-out.
 If it is another color, refer to the CIC Pro Service Manual provided with
your system for the cause since this indicates that it is not RF drop-out.
5. Type setflags<Space>-mark<Space>off and press Enter on the keyboard to
turn off drop-out flags.
6. Close the Command prompt window and the CIC Setup window.
Yellow drop-out condition

Determine the source of the problem
1. Verify the patient/transmitter is in the coverage area. If not, the system is not
at fault.
2. On the CIC Pro:
 Ensure that you are viewing all leads for the patient/transmitter.
 If the status is Leads Fail, correct the system. Refer to the operator’s
manual provided with your system.
NOTE
If a shorted-leadwire set is used, an Asystole alarm will sound if the
transmitter is admitted. This alarm can be silenced by turning off all
alarms for this admitted bed.
3. Check the transmitter battery status. If the status is Low Batt, correct the
condition by replacing the batteries with new ones.
NOTE
If needed, refer to the appropriate ApexPro Telemetry Service Manual or
the operator’s manual provided with your system.
2001989-469A ApexPro 5-5

Troubleshooting
4. Isolate whether the drop-out is related to single or multiple patients in the

same coverage area by verifying if more than one transmitter is dropping out
in that coverage area.
 If multiple transmitters drop out in the same coverage area, suspect the
antenna system. See Antenna system troubleshooting on page 5-8.
 If only one transmitter is dropping out, suspect transmitter or receiver.
Follow the steps to “Troubleshoot the transmitter” on page 5-6 or
“Troubleshoot the receiver” on page 5-6 for specific troubleshooting
techniques.
Troubleshoot the transmitter

If the drop-out is related to only a single patient/transmitter, use the following
instructions to duplicate the transmitter on another receiver.
1. From the main CIC Pro screen, select the Setup CIC button.
3. Type the password mms_com and then select OK. A Command prompt
window is displayed.
4. Type setflags<Space>-dup<Space>on and press Enter on the keyboard to
allow duplicate transmitters.
NOTE
Once you select this option, you have five minutes to enter the duplicate
TTX numbers. If that is not enough time, simply select this option again
and continue entering TTX numbers.
5. At the CIC Pro center, admit a duplicate TTX four times. You should have the
same TTX admitted five times. This will ensure that the TTX is admitted to at
least two different receiver cards.
6. Type setflags<Space>-dup<Space>off and press Enter on the keyboard
when you want to turn off duplicate TTX.
7. Close the Command prompt window and the CIC Setup window.
 If drop-out continues on both receivers, suspect the transmitter. Swap
the transmitter with a known good transmitter. Drop-out should go away.
 If drop-out is on one receiver and not the other, See Troubleshoot the
receiver on page 5-6.
Troubleshoot the receiver

If drop-out is on one receiver and not on the other, use the ApexPro Telemetry
Server Service Manual provided with your system to complete the following steps.
1. Isolate which receiver subsystem is attached to the CIC Pro center you’re
viewing by using the service diagnostic tool PTSCONFIG at the CIC Pro center/
telemetry server and the command “blink patient unit|bed*” in order to
associate a care unit/bed number to a receiver in a given rack.
2. Once the receiver subsystem is known, check all LEDs for proper operation.
Verify their status with the “Receiver Subsystem LED status chart” on page 5-
13.
5-6 ApexPro 2001989-469A

Troubleshooting
3. Swap the suspected receiver with a known good receiver card. Drop-out
should go away.
If drop-out does not go away, suspect an antenna coverage problem. See
Antenna system troubleshooting on page 5-8.
Quick antenna system checks

1. Check all antennas:
a. Check to see if each antenna’s LED is illuminated.
b. If any antenna’s LED is not illuminated, make sure its power supply is
powered. Apply power to the antenna power supply if necessary.
c. Make sure all cables are properly connected.
d. Replace the power supply if necessary.
e. Replace the antenna if necessary.
2. If all antennas are okay, check the antenna amplifiers.
a. Check to see if each antenna amplifier’s LED is illuminated.
b. Make sure the amplifier is properly oriented regarding RF In and DC Out.
c. Make sure all cables are properly connected.
d. Replace any faulty unit(s).
NOTE
If an identical replacement part cannot be found, contact the ND&I
Team to ensure proper system balancing.

Troubleshooting
Antenna system troubleshooting

Complete Antenna Infrastructure Tests
To troubleshoot the antenna system, begin by performing the “Antenna
infrastructure tests” on page 4-3. In many cases this helps to isolate the issue. A
failure of the Unity Signal Gain Test may indicate an issue with one or more
components of the antenna run. In this case, complete the “Antenna run fault
isolation procedure” on page 5-8.
Antenna run fault isolation procedure

Before beginning the antenna run fault isolation procedure, obtain the following
site documentation:
 Floor plan with antenna placement
 Rack diagram
 Splitter Board Design Document
 Loss calc spreadsheet and/or Clinical Systems Design Tool for site (if
available)
1. Identify the antenna run, or runs, that failed the unity signal gain test.
2. Using the site design documents, verify that the installation matches the
design. If it does not match, contact ND&I for assistance.
3. If all the antennas associated with one receiver input failed the test, focus on
common components of the run to adjust or replace, for example, the
amplifier.
4. If a subset of the antennas associated with one input to the receiver fails,
focus on unique components of that run to adjust or replace. An example
would be the active antenna itself.
5. After adjustment or replacement of component(s), repeat the unity signal
gain test and perform any applicable check out procedures if components
were replaced.

ApexPro transmitter carrier impairment measurement

procedure
Rationale for test
The purpose of this test is to compare the transmitter’s carrier level to the
transmitter’s modulated output. The transmitter’s carrier level must be at least 30
dB below the transmitter’s modulated output, otherwise the signal will interfere
with the modulated output and cause drop-out. This test verifies that the carrier
level conforms to this requirement. This test is not required for ApexPro CH or
CARESCAPE telemetry T4 or T14 transmitters.
NOTE
The “ApexPro transmitter troubleshooting tree” on page 5-4 references this
test.
Equipment needed
 Spectrum Analyzer (Rohde & Schwarz FSH3 preferred)
 N-connector-to-BNC-connector adapter (attached)
 ApexPro transmitter (PN 418500-XXX)
 Rubber duck antenna

Event logs
Events can be stored in two locations, the receiver system and the ApexPro host
hard drive.
5-18 ApexPro 2001989-469A

Troubleshooting
Receiver system event logs

Events logged to the receiver system are stored in flash memory and can be
retrieved via the diagnostic service port. The system stores the events in two flash
memory sectors. When the event storage maximum is reached, and a new event
occurs, the flash sector with the oldest events is erased. New events are stored to
that sector.
Access the receiver system event logs as follows.
1. Using the 9-pin, serial cable supplied with the transmitter programming kit,
connect a PC to Async Comm (asynchronous serial communication).
the ComPort connection.
5. Press Enter.
There is no command to view how many events are stored, but typically the
most recent event will be examined first. Event 1 is the first (oldest) stored
event.
Use the del (display error log) command with a parameter of 999 to
determine the number of events stored. Since 999 is greater than the number
of events that can be stored, the command errors and reports the number of
events in the system.
6. At the @> prompt type del 999 and press Enter. The following displays.
@> del 999

Record not present, XXX records stored in system.
NOTE
“XXX” is representative of the number of events stored in the error log. It
will appear on screen as an actual number.
7. At the @> prompt type del XXX (where XXX equals the number of events as
indicated in the error message) and press Enter to display the most recent
event.
Other commands include:

 Type , (comma) and press Enter to display the previous log entry.
 Type . (period) and press Enter to display the next log entry.
 Type dael and press Enter to dump all entries. This is useful in conjunction
with the “capture-to-file” feature of Hyperterminal, which is located in the

Troubleshooting
Before calling service

Before calling service on a transmitter that may appear to be operating
incorrectly or may have failed, check the following.
System dropout
If you suspect any system-related dropout or if you are not sure what the problem
is, consult the ApexPro System Troubleshooting Instructions or the Enterprise
Access Service Manual Troubleshooting section as applicable, available to GE
service personnel.
Transmitter
Frequent lead fail
 Swap the leadwire set with either a new set or a known good set. Leadwires
may have hidden internal damage that can cause signal failure.
 Leadwires may become brittle or damaged after frequent cleanings. Inspect
them before each use and replaced if damaged.
 Leadwires that have been wrapped around the transmitter are more likely to
be damaged. Use a transmitter holder when the transmitter is not in use.
Leadwires should be either laid out flat or hung up such that there are no
kinks or sharp bends in the wires.
 Check the electrodes on the patient. Improper preparation can cause Lead
Fail events.
 Should Lead Fail events continue to occur regularly, a call for service may be
necessary.
 If, after powering up the transmitter, only the RA LED flashes rapidly:
 The transmitter has lost its memory.
 The application code contained in the EEPROM has been erased or
corrupted.
 The transmitter needs to be reprogrammed.
 Return the transmitter to the factory for service.
 If, after powering up the transmitter, only the LA LED flashes rapidly:
 The transmitter has lost its memory.
 The manufacturing/service code contained in the EEPROM has been
erased or corrupted.
 The transmitter needs to be reprogrammed.
 Return the transmitter to the factory for service or contact Technical
Support.
Short battery life

 Install a new set of alkaline AA batteries into the transmitter and then verify
battery life.
2001989-469A ApexPro 5-21

Troubleshooting
 Once used in a transmitter for any length of time, dispose of (recycle) used
batteries immediately.
 Batteries must NOT be re-used for telemetry. Use batteries for only one
patient. DO NOT store used batteries for use with the next patient. A battery
contains a finite amount of stored energy. Each unit of time a battery is used
diminishes the amount of stored energy. Installing a used battery in a
transmitter results in a greatly reduced, and unpredictable, monitoring
period.
 NEVER use a battery beyond the recommended expiration date for the
battery. The amount of stored energy in the battery may not be sufficient for
proper monitoring.
 DO NOT use rechargeable batteries. The transmitter circuitry, Apex Oximeter,
and the Accutracker were designed for the power output characteristics of
alkaline batteries.
NOTE
Rechargeable batteries DO NOT store as much energy as alkaline
batteries and have very different output characteristics. The monitoring
period may be greatly shortened and the specified low-battery warnings
may be adversely affected or possibly not even displayed.
 If, after working through the above steps, your transmitter still has a short
battery life, a call for service may be necessary.
Waveform dropout
 To determine the type of dropout, enable flags as described in “RF signal
integrity” on page 7-16.
 If out of antenna range, position the transmitter within range of the antenna.
 Check the voltage levels of the batteries. If the voltage level is below the
acceptable value as listed in “Switches/LEDs” on page 2-14, replace the
batteries. Alternatively, you can replace the batteries and see if the waveform
is displayed properly.
 For external RF interference, use the spectrum analyzer to verify the external
noise and reprogram the transmitter if necessary.
 If you suspect a bad transmitter, perform checkout procedure. (See Checkout
on page 7-1.) Return to service if defective.
Synthesizer lock error

If the transmitter can not operate at its programmed frequency, a synthesizer
lock error occurs. For the CH, T4, and T14 transmitter, the Change Battery and Va
LEDs will be lit although the transmitter halts operation. Try resetting the
transmitter by sliding the battery compartment cover open and closed again. If
this does not resolve the problem, return the transmitter to the factory for service.
Additional problem resolution

If you are not sure which component in the telemetry system may be operating
incorrectly or may have failed or if the above information does not resolve the
problem, please contact GE technical support.

Troubleshooting
Apex oximeter and Nonin Xpod oximeter

Refer to the appropriate ApexPro Telemetry System Operator’s Manual for
troubleshooting messages for the oximeters.
Apex oximeter short battery life

 A change battery condition is indicated by the Apex Oximeter display flashing
and displaying a message at the CIC Pro center. If the batteries are not
changed within 1 hour, the oximeter’s display flashes dashes, the sensor LED
turn off, and no data displays on the CIC Pro center.
 Install a new set of alkaline AA batteries into the oximeter and then verify
battery life.
 Once used in an oximeter for any length of time, dispose of (recycle) used
batteries immediately.
 Batteries must NOT be re-used. Use batteries for only one patient. DO NOT
store used batteries for use with the next patient. A battery contains a finite
amount of stored energy. Each unit of time a battery is used diminishes the
amount of stored energy. Installing a used battery in an oximeter results in a
greatly reduced, and unpredictable, monitoring period.
 NEVER use a battery beyond the recommended expiration date for the
battery. The amount of stored energy in the battery may not be sufficient for
proper monitoring.
 DO NOT use rechargeable batteries. The oximeter circuitry was designed for
the power output characteristics of alkaline batteries.
NOTE
Rechargeable batteries DO NOT store as much energy as alkaline
batteries and have very different output characteristics. The monitoring
period may be greatly shortened and the specified low-battery warnings
may be adversely affected or possibly not even displayed.
 If, after working through the above steps, your oximeter still has a short
battery life, a call for service may be necessary.
Power shutdown during leads fail

ApexPro transmitter
If all leads fail for more than about eight seconds, the digital signal processor
shuts off power supplied to the RF output amplifier. This reduces the battery
discharge rate when no data actually transmits.
Once the leads are reconnected, about one second is required for the digital
signal processor to power up the RF circuitry and resume transmitting patient
data.
2001989-469A ApexPro 5-23

Troubleshooting
ApexPro CH, T4 and T14 transmitters

If all leads fail for more than about eight seconds, the digital signal processor
shuts off the VCO regulator causing the RF output to be turned off.
Once the leads are reconnected or if a button is pressed, about one second is
required for the digital signal processor to power up the VCO regulator. If the
leads are still bad after a button is pressed the VCO regulator will turn off again
(the RF turns on for 70 seconds for Verify Leads button press, 15 seconds for the
other buttons).
If the transmitter is reporting a synthesizer lock error the VCO regulator will be
turned off.

Bandpass filters
When an antenna system is designed only with notch filters rather than with the
bandpass filter, the use of multiple notch filters can cause excessive signal loss. In
addition, whenever a new TV station is activated in the vicinity, the antenna
system must be redesigned and corresponding notch filters must be installed.
In general, bandpass filters eliminate the need for notch filters on every channel.
They pass only the channel of interest and reject other channels. The result is
fewer parts to install, significant reduction of signal loss in the desired channel,
and no redesign of the system to accommodate new TV stations.
ApexPro bandpass filter 608-614 MHz

The 608-614 MHz bandpass filter passes channel 37 and rejects all other
channels, except for portions of channels 36 and 38. Continue to use channels 36
and 38 in all systems and in older antenna systems where multiple notch filters
are used.

Electrical safety tests

Electrical safety tests provide a method of determining if potential electrical
health hazards to the patient or operator of the device exist.
Recommendations
Test conditions – Electrical safety tests may be performed under normal ambient
conditions of temperature, humidity, and pressure.
Test equipment – The recommended test equipment required to perform

electrical safety tests is listed below.
Item Specification
Leakage Current Tester Equivalent to the circuits

shown

Checkout
Ground Bond Tester 0 – 1 ohm
ECG Test Body All leads together
Power outlet test

Before starting the tests, the power outlet from which the monitoring device will
get electrical power must be checked. This test checks the condition of the power
outlet to ensure correct results from leakage tests.
For international power outlets, refer to the internal standards agencies of that
particular country. Use a digital multimeter to ensure the power outlet is wired
properly.
If other than normal polarity and ground is indicated, corrective action must be
taken before proceeding. The results of the following tests will be meaningless
unless a properly wired power outlet is used.
Ground (earth) integrity

Listed below are two methods for checking the ground (earth) integrity, “Ground
Continuity Test” and “Impedance of Protective Earth Connection.” These tests
determine whether the device's exposed metal and power inlet's earth (ground)
connection has a power ground fault condition.
Ground
Pin
Perform the test method below that is required by your Country/Local governing
safety organization.
Ground continuity test

Completion of this test is checked by the following steps:
1. Disconnect the device under test from the power outlet.

2. Connect the negative (-) lead of the DMM to the protective earth terminal
(ground pin in power inlet connector) or the protective earth pin in the Mains
plug (ground pin in power cord). Refer to the US 120 VAC power cord figure
above.
3. Set the DMM to the milliohm (mW) range.
4. Connect the positive (+) lead of the DMM to all exposed metal surfaces on the
device under test. If the metal surfaces are anodized or painted, scrape off a
small area in a inconspicuous place for the probe to make contact with the
metal.
5. Resistance must read:
 0.1 ohm or less without power cord
 0.2 ohms or less with power cord
7-8 ApexPro 2001989-469A

Checkout
Impedance of protective earth connection

This test, unlike a ground continuity test, will also stress the ground system by
using special ground bond testers.
This test normally is only required as a manufacturing production test to receive

safety agency compliance (i.e., IEC 60601-1).
Some country agencies do require this test after field equipment repairs (i.e.
Germany's DIN VDE 0751 standards).
Consult your country/local safety agency if in question.
Compliance is checked by the following steps:
1. A current not less than 10 A and not exceeding 25 A from a current source
with a frequency of 50 or 60 Hz with a no-load voltage not exceeding 6 V is
passed for at least 5 s through the protective earth terminal or the protective
earth pin in the mains plug and each accessible metal part which could
become live in case of failure in basic insulation.
2. The voltage drop between the parts described is measured and the
impedance determined from the current and voltage drop. It shall not exceed
the values indicated.
For equipment without a power supply cord, the impedance between the
protective earth terminal and any accessible metal part which is protectively
earthed shall not exceed 0.1 ohms
For equipment with a power supply cord, the impedance between the protective
earth pin in the mains plug and any accessible metal part which is protectively
earthed shall not exceed 0.2 ohms.
When taking this measurement, move the unit's power cord around. There should
be no fluctuations in resistance.
Ground (earth) wire leakage current tests

Perform this test to measure current leakage through the ground (earth) wire of
the equipment during normal operation.
NOTE
The DMM plus leakage tester network shown is the circuitry defined by the UL
60601-1 standard for measuring leakage current.

Additional system tests

Power-up self-tests
Transmitter
The transmitter performs a limited amount of testing of the internal memory
components when it powers up. The results of these tests are indicated by the
LEDs on the transmitter case. Test results may also be viewed on a remote
terminal or personal computer if the ApexPro transmitter programming box is
connected and in use.
To start the tests, install new batteries into the transmitter. The internal digital
signal processor performs the self-tests automatically.
NOTE
Any test failures are stored and appear when you view TTX information

during programming of the transmitter. Stored errors can only be cleared by

reprogramming the transmitter.
The following functions are performed at power-up of the transmitter.
1. First, a memory test is performed. The memory in the transmitter’s digital

signal processor circuit either passes or fails this test.
 EEPROM memory is copied to RAM memory.
 The copy is verified with a checksum test.
 If the checksum test passes, testing continues.
 If the checksum test fails, a checksum error is logged and the memory
test is repeated. This test continues in a loop as long as the test fails and
power is applied to the transmitter, indicated by all LEDs flashing rapidly
then pausing repeatedly.
 The Checksum Error status is displayed in the power-up self-test results
of the Apex & ApexPro Tx Config program for programming the
transmitter.
2. Next, the transmitter’s frequency synthesizer is programmed with the

specified customer’s frequency. A test is performed to verify a successful lock
of the synthesizer circuits.
 If the synthesizer lock test passes, the transmitter starts normal
operation.
 If an error is detected, the transmitter creates a Synthesizer Lock log
which indicates if the transmitter was ever unable to operate at its
programmed frequency.
 The Synthesizer Lock status is displayed in the power-up self-test results
of the Apex & ApexPro Tx Config program for programming the
transmitter.
During normal operation, a ROM test is executed continuously. If an error is

detected, the transmitter resets itself.

NOTE
Make sure no external pressure is applied to the Accutracker when you
turn it on.
2. Press and hold the button and turn the Accutracker on. The unit is now in
Technical Calibrate mode and valve #1 is closed.
3. Apply pressures to the Accutracker between 0 mmHg and 250 mmHg in
increments of 50 mmHg. Make sure there is no more than a +/–2 mmHg
difference between the mercury column or PDM200 display and the
Accutracker display value.
4. Turn off the Accutracker.
5. After five seconds (to prevent the unit from “locking up”), press and hold the
button and turn the Accutracker on.
6. Press the button twice; then press the button to force the Accutracker
to activate the pump and valve circuitry. The unit goes through a diagnostic
self-test. If the unit passes the test, TEST PASSED displays briefly.
7. When OFFICE SELF TEST displays, immediately press the button to

discontinue the reading in progress. This step is necessary to identify that a
reading can be aborted, if necessary, during a test in case there is a problem
(i.e., the cuff slips down the arm, an electrode becomes detached, etc.).
8. Turn the Accutracker off to exit this mode.
Over-pressure release check

The Over-Pressure release occurs whenever a pressure of 285 mmHg (+/–20
mmHg) is applied to the Accutracker pressure transducer. The Over-Pressure
release forces the pump to stop and valve #1 to open.
7-22 ApexPro 2001989-469A

1. Press and hold the button and turn the Accutracker on.
NOTE
turn it on.
2. Apply a pressure of 285 mmHg (+/–20 mmHg) to the Accutracker. Valve #1

immediately opens and allows the applied pressure to release.
3. Once the Over-Pressure circuit is tripped, valve #1 and the pump are disabled
until “Analog Power” (+/–Vana) is removed from the circuit. Turn the
Accutracker off to reset the circuit.
Hardware time-out and system leak check

1. Press and hold the button and turn the Accutracker on.
NOTE
turn it on.
2. Apply 200 mmHg pressure to the Accutracker pressure circuit and start a
timer to clock the Hardware Time-Out circuit.
3. The Hardware Time-Out occurs in three minutes (+/–45 seconds). Valve #1
opens and dumps pressure once the time-out is finished. As you monitor the
Time-Out, monitor the pressure (in mmHg) displayed on the Accutracker LCD.
The Accutracker should leak no more than 2 mmHg per minute.
Communication test
This procedure verifies that the telemetry system transmits and receives the data
correctly from the Accutracker.
1. Attach the Accutracker to the ApexPro Telemetry system.

NOTE
You must have ECG leads with a shorting cable or simulator attached to
the ApexPro Telemetry system for this test to work.
CAUTION
Refer to the appropriate ApexPro operator’s manual for proper
operation guidelines and cuff/microphone placement.
2. Place blood pressure cuff on the arm.
3. Turn the Accutracker on and press the button.

4. When the display appears on the system screen, verify that the Accutracker
display numbers match the display numbers.
5. Turn Accutracker off.

Compliance
level
Interference may occur in the vicinity of

equipment marked with the following
symbol:
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by reflection from
structures, objects, and people.
aField strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the equipment is used exceeds the applicable RF compliance level
above, the equipment should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the equipment.
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 0.3 V/m.
c The low power design does not allow the use of high dynamic range operational amplifiers. To further reduce size,
the ECG section utilizes single supply topology, and unshielded Flex assemblies. The result of the above mentioned
design choices results in a design that provides acceptable performance in the clinical environment.
Recommended separation distances

The following table provides the recommended separation distances (in meters)
between portable and mobile RF communications equipment and the
