9. Remote Control Function & Operation
9.1. Introduction
Currently, mAs, kV and Pre-set memory techniques (PROM memory) can be selected by the operator
by depressing push switches on the operation panel. Each technique or mode selection depends on
an anatomic region or view for radiographic examination. The collimator lamp is turned on by the lamp
push-button and turned off by a 30 second collimator timer run off.
Many portable operators and field users have suggested we find a better way to select an exposure
technique and parameters along with mAs, kV and pre-set PROM memory values. Most field
operators hold portable X-Ray units with one hand, while holding the exposure hand switch with the
other hand. This makes selecting technique factors on the control panel awkward without dropping the
portable unit or hand switch. We have modified our X-ray portable software and functions of the PREP
and Exposure hand switch to allow selection of all exposure parameters (mAs & kV) and control of the
collimator lamp.
The exposure hand switch consists of a two step hand switch. The 1 step of the hand switch is called
st
the Preparation (PREP or Ready) step. The 2 step of the hand switch is called the Exposure (Exp. or
nd
X-Ray out) step.
All functions of the remote control described above are executed by clicking the first stage on the hand
switch which is the PREP mode of operation. Each remote control function and technique value
selection is described below.
Stand-by Ready (1 step, PREP mode) Exposure (2 step)

st nd
19
9.2. Remote Control Mode

The kV and mAs setting, memory selection and collimator lamp is controlled remotely by the hand
switch by pressing the PREP step push-button as follows:
ATTENTION
Click the PREP hand switch three times consecutively. This will allow you to
enter in the remote hand control menu mode for operation.
<Triple Click>
9.2.1. Memory Selection

When you click the PREP step hand switch quickly three times, the Pre-set Memory station LED
(PXP-60HF: 1-8) will blink sequentially as well as the kV and mAs LED readouts. Make a single click
with the hand switch when the desired pre-set memory station lamp begins to blink. This will cause
the pre-set memory data to be selected and displayed in the control LCD window.
NOTE
All pre-set memory data should be entered and stored at each memory station (PXP-60HF: 1-8),
prior to performing the above mode of operation.
9.2.2. kV Selection
One click of the PREP step switch will cause the kV LED readout to blink. You will now be in the kV
selection menu mode. The kV values increase by one kV unit per click of the PREP step switch. If you
depress and hold the PREP step switch for a few seconds, the kV readout will increases rapidly up to
the maximum value (PXP-60HF: 100 kV). The kV readout will circulate from lowest to highest values
as long as you hold and press the button. When the desired kV readout appears on the control display
panel, release the PREP step hand switch and wait for a few seconds. The kV value will set up
automatically.
20
9.2.3. mAs Selection

mAs selection is similar to the kV selection mode. Click the PREP step hand switch once to make the
mAs LED readout blink. You will be in the mAs selection menu mode. The mAs value will increase with
each click of the PREP step switch (0.4 mAs to the maximum mAs of each portable x-ray unit). If you
wish to increase the mAs value quickly, simply hold the PREP step switch down one stage. (PXP-
60HF: 100 mAs). The mAs readout will circulate as long as you hold the PREP step switch. When the
desired mAs readout appears on the control display panel, release the prep hand switch and wait for a
few seconds. Then mAs value will set automatically.
9.2.4. Collimator Turned ON
ATTENTION
Click the PREP step hand switch rapidly twice. The collimator lamp will
illuminate for X-ray exposure positioning.
<Double Click>
With the exposure technique (mAs & kV) set with your remote hand switch, you are ready to make a
radiographic exposure for examination. It is very important to position the right region of interest on a
patient’s anatomy. Therefore, the collimator beam must be turned on to confirm the size of region and
size of film covered. When the PREP step switch is rapidly clicked twice, the collimator lamp will turn
on simultaneously until the lamp timer (30 seconds) runs off.
However, it will turn off automatically when x-ray exposure sequence is completed.
9.3. X-RAY EXPOSURE
WARNING
When an X-ray exposure is made in a room or outdoors, lower radiation will scatter throughout the
surrounding area. An authorized operator is expected to take precautions and is highly recommended
to wear a lead apron and gloves if necessary for your patient’s and your own protection.
After the x-ray exposure technique is selected and collimator light beam size is adjusted with the
collimator blade knob, an x-ray exposure can be made by an authorized individual of the medical clinic
or hospital.
X-RAY EXPOSURE SEQUENCE:

A. Press the PREP step hand switch (1 step) and hold
