2 INITIAL OPERATION
Initial operation
Before delivery, every high-frequency surgical unit is tested by the manufacturer in regard to its
function and safety. To ensure that the unit also functions safely after shipping and installation at
the operator’s site, the following points should be observed:
The operator should only operate the high-frequency surgical unit if the manufacturer or supplier
2. has instructed the parties responsible for operation of the unit in handling of the unit by
means of the instruction manual.
2-1

3 RISKS AND SAFETY OF HIGH-FREQUENCY SURGERY
WARNING
The patient must be insulated against electrically conductive objects during high-frequency
surgery. The black elastic table covers on operating tables demonstrate a certain electrical
conductivity for diverting electrical charges. Therefore they are never suitable for ensuring the
required insulation of the patient against metal parts of the operating table. For this reason, an
electrically insulating intermediate layer, for example dry cover cloths, must be laid between the
patient and this black operating table cover during the application of high-frequency surgery.
If it is possible for this intermediate layer to become wet during the operation, for example due
to perspiration, irrigation liquid, urine etc., wetting of these intermediate layers must be prevented
by a watertight sheet of plastic. Urine should be carried away via catheter.
Extremities lying against the trunk or skin-to-skin contact points should be insulated from
one another by laying dry cover cloths between them.
Do not apply ECG electrodes closer than 15 cm next to the operating field.
Needle electrodes or injection cannulae should not be used as ECG electrodes during
high-frequency surgery.
3-1
3.1.2 Unintentional activation of an HF generator
Unintentional activation of an HF generator can lead to burns on the patient if the active electrode
hereby touches the patient directly or indirectly through electrically conductive objects or wet
cloths.
WARNING
The lines to the active electrodes should be positioned in such a way that they touch
neither the patient nor other lines.
Always set the acoustic signal, which indicates the active status of the high-frequency
generator, so that it can be easily heard.
For operations in which the cutting or coagulation electrode unavoidably remains in contact
with the patient even in a nonactive condition, e.g. for endoscopic operations, particular
care is required. If such an electrode is unintentionally activated due to an error, this activated
electrode should then not be removed from the body without special supervision. When
removing the activated electrode from the patient’s body, burns can result on all areas
within the body which come into contact with the activated electrode. For this reason, in
case such errors occur, the power switch for the high-frequency surgical unit should be
switched off immediately before an attempt is made to remove the activated electrode
from the body.
3-2
3.1.3 Unintentional thermal tissue damage due to inappropriate application
Generally speaking, the bipolar coagulation technique should be applied in preference to the
monopolar coagulation technique. This particularly applies to coagulations on straight organs,
on which the high-frequency current flows over longer areas through diameters which are
approximately equal or become even smaller.
WARNING
Always make certain that the HF current does not flow through thin tissue structures or vessels
with a small diameter.
The neutral electrode must be applied with its entire surface as closely and reliably as possible to
the operating field on the patient’s body.
3-3
WARNING
The effective contact surface, i.e. the electrical conductive value between the neutral electrode
and the patient must correspond to the HF capacity used, meaning the intensity of the HF current.
Here the effective contact surface means the surface of the neutral electrode which has electrically
conductive contact to the skin of the patient during high-frequency surgery.
a) b)
Fig.: The neutral electrode must be applied at an appropriate location on the patient’s skin using the
entire contact surface available (a). If the neutral electrode has only partial contact to the patient’s skin (b),
there is a risk that burning will occur at this location
When using an instrument with electric insulation, it is necessary to be certain that these insulations
are not overloaded and destroyed by overly high electric voltages. The electric output voltages
for the high-frequency surgical unit are indicated for the various cutting and coagulation modes
relative to the possible settings in this instruction manual. The electric strength of the instrument
insulation can be found in the technical data for the instruments or, in case of doubt, can be
requested from the manufacturer of the respective instrument.
WARNING
All insulation on electrodes, electrode holders, cables, plugs etc. must be in perfect condition.
3-4
3.1.6 Unintentional thermal tissue damage due to inattentiveness
Like a scalpel, high-frequency surgery is always a potential source of danger if handled without
care.
WARNING
The cutting or coagulation electrodes should always be handled with care and laid aside in the
intervals between use so that neither the patient nor other persons can come in contact with the
electrodes.
Laying unused electrode handles or coagulation forceps on the patient, next to the patient or
within folds on the cover cloths is dangerous. Cases of burns on patients are known which were
caused by laying the coagulation forceps within folds on the cover cloths which penetrated
through the cloths into the patient’s skin and resulted in burns without being noticed.
WARNING
The intensity for cutting or coagulation should only be set and only activated for as long as
necessary for the intended purpose.
An insufficient effect at a standard setting can, for example, be caused by poor attachment of the
neutral electrode, poor contact in the connectors, defective cables or electrically insulating tissue
remnants on the active electrode. This must be checked before setting at a higher power.
3-5
WARNING
Make certain during high-frequency surgical operations that anesthetics, skin cleaning agents
and disinfectants are nonflammable. If their use is unavoidable, they must have completely
evaporated and the vapor must be removed from the area of spark formation before switching on
the high-frequency surgical unit.
WARNING
Tissue can be unintentionally burnt immediately after cutting and/or coagulation procedures if
electrodes that are still hot touch the tissue. Attention must be especially paid to this during
endoscopic operations, such as during pelviscopic fallopian tube coagulation or during endoscopic
polypectomy.
Electric alternating current with a frequency above 300 kHz is unable to stimulate nerves and
muscles.
3-6
During cutting procedures, forced coagulation and spray coagulation, the unavoidable electric
arcs between an active electrode and the tissue nevertheless have the effect that a portion of the
high-frequency alternating current is rectified, from which more or less strongly modulated,
low-frequency current components result which stimulate electrically stimulable structures such
as nerves and muscles.
WARNING
When installing or arranging sensitive electronic equipment in the operating room, this problem
should be taken into consideration. In principle, sensitive electronic equipment should be set up
as far as possible from the high-frequency surgical unit and particularly from the cables providing
HF current. In addition, the cables providing HF current, which act like broadcast antennas,
should not be unnecessarily long and should never be positioned parallel or too close to cables
from sensitive electronic equipment.
The unit has been fitted with a special generator in consideration of the disturbance of sensitive
electronic equipment, which generates a relatively low interference level as compared to
conventional high-frequency surgical units.

4 DESCRIPTION OF THE HIGH-FREQUENCY SURGICAL UNIT
4-1
Soft coagulation
Soft coagulation can be activated by key or pedal.
Forced coagulation
Forced coagulation is advantageous if an efficient hemostasis is to be achieved with relatively
small-surface electrodes, such as TUR resection loops.
Spray coagulation
The Spray coagulation mode on the ICC is also suitable for Argon Gas coagulation.
Bipolar coagulation
In this coagulation mode, the HF voltage is, similar to Soft coagulation, automatically and
constantly controlled, and its peak value always remains lower than 200 Vp, so that the current
density and thus the coagulation effect is, for the most part, independent of the effective contact
surface between the coagulation electrode and the tissue, provided the effective contact surface
is not too large relative to the currently set power limitation.
The adjustable power limitation serves the purpose of protecting fine bipolar coagulation
instruments, such as pointed bipolar coagulation forceps, from being thermally destroyed in
case of a short between the two forcep tips.
In the Auto Start mode, the HF generator is automatically activated if both poles of the bipolar
coagulation instruments used contact electrically conductive tissue simultaneously. Auto Start
can occur either immediately at the moment of contact with the tissue or more or less temporally
delayed. With immediate activation, it is possible to work very quickly, especially if several
coagulations must be performed one after another. Delayed activation offers the operator the
advantage that he/she can prepare and securely grasp the tissue to be coagulated with the bipolar
coagulation forceps before the HF generator is automatically activated. Automatic activation of
the HF generator only occurs if both poles of the bipolar coagulation instruments contact the
tissue uninterruptedly for at least as long as the respectively selected delay lasts. If the contact is
interrupted before the respectively selected period of delay is over, the respective period of
delay restarts as of the next contact.
4-2
4.2 Description of the controls
The figures set in cursive relate to the ICC illustration for this chapter, or to the function
fields in the text.
1 Power switch
Using this power switch, the unit is switched on and off.
Each time after being switched on, the unit automatically proceeds with various performance
checks. If an error in the unit or in the accessories is recognized here, a warning signal
sounds and the determined error is indicated by a corresponding error number. (See Chapter
8.1, Automatic performance checks after switching on the unit). If no error is determined,
the unit is ready to operate.
If the unit was switched off for less than approx. 15 seconds, all settings for the program
used before switching off appear after the automatic performance check on the front panel,
and the unit can be immediately reactivated. This is advantageous if, for example, the
power supply briefly fails.
If the unit was switched off for longer than approx. 15 seconds, the basic setting of the
program used before switching off appears after the automatic performance check on the
front panel, whereby all relevant visual displays continue to blink and the unit cannot be
activated until any key on the front panel is briefly pressed as confirmation that this program
should be used. Then the relevant displays are continously illuminated and the unit can be
activated using the available settings. These settings can be changed or adapted to the
current requirements at any time. However, other programs can be selected as well.
2 - 4 Function fields
The AUTO CUT, AUTO COAG and AUTO BIPOLAR function fields can be adjusted
separately from one another, although not activated simultaneously for reasons of safety.
WARNING
Function fields that are not used may be switched off completely to prevent unintentional
activation. To do this, the power limitation must be set down so far in the corresponding function
field until a beep is heard and “ —“ appears on the digital display. The corresponding function
field cannot be activated in this condition..
4-3
2 AUTO CUT function field
All parameters can be set in this function field that are relevant to
cutting:
The required Cut mode “AUTO CUT“ or “HIGH CUT“ can be set here. In “AUTO CUT“
mode, the HF voltage is constant. In the “HIGH CUT“ mode, the intensity of the arc
between the active electrode and the tissue is constant.
4-4
3 AUTO COAG function field
All parameters can be set in this function field that are
relevant to coagulation:
Activation
The coagulation modes for this AUTO COAG function field can be activated via the blue key on
an electrode handle or via the blue pedal on a footswitch. Activation is visually signaled by
continuous illumination of the triangle symbols in the upper part of the AUTO COAG function
field as well as acoustically signaled.
4-5
4 AUTO BIPOLAR function field
In this function field, all parameters can be set
that are relevant to bipolar coagulation:
The operator can use the start delay, for example, to prepare or safely grasp the tissue to
be coagulated with the coagulation forceps before starting.
WARNING
Only use Auto Start if unintentional contact of tissue with the coagulation instrument can be
safely avoided. For endoscopic interventions, such as laparoscopy, pelviscopy or thoracoscopy,
Auto Start should not be used because unintentional contact of the coagulation instrument with
tissue cannot be safely avoided here.
In some countries the ICC units are supplied with the AUTO START function deactivated. This
may also apply in your case. If you nevertheless wish to use the AUTO START function, please
consult your local ERBE branch office. You will find the address on the last page of the Instruction
Manual. Technical Service will activate the AUTO START function for you on request.
The AUTO START key has no function on the ICC 300 H No. 10128-075 and ICC 300 E
No. 10128-076.
4-6
4.4 Activation, changeover switch for the blue pedal of a dual-pedal footswitch
If the right signal 4.4.1 is illuminated in this key, the Auto Bipolar can be started via the
blue pedal on a dual-pedal footswitch. Auto Bipolar can also be activated via the white
pedal on a single-pedal footswitch or by Auto Start.
5 Connecting socket for neutral electrodes
For monopolar cutting and/or coagulation, a suitable neutral electrode must be used that must
both be connected to the unit as well as carefully applied to the patient.
The ICC is equipped with a Neutral Electrode Safety System (NESSY) which automatically
monitors the electrical connection between the neutral electrode and the unit as well as application
of the neutral electrode on the patient. The latter only then however if neutral electrodes with
two contact surfaces are used (See Chapter 4.3.3 NESSY).
WARNING
If single-surface neutral electrodes are used, NESSY only monitors the electrical connection
between the neutral electrode and the unit, but not the application of the neutral electrode on the
patient.
The pictograms beside the connecting socket for neutral electrodes have the following explanation:
6 Connecting socket for the AUTO CUT and AUTO COAG function fields
Electrode handle with fingerswitches can be operated from this connecting socket. This connecting
socket can only be activated via the fingerswitch.
7 Connecting socket for the AUTO CUT and AUTO COAG function fields
Electrode handles or other monopolar coagulation instruments with or without fingerswitches
can be operated from this connecting socket. Also other monopolar instruments with or without
switches, such as rigid or flexible endoscopes for endoscopic operations, can be connected to
this connecting socket. Make certain here that the plug type is suitable. This connecting socket
can either be activated via the fingerswitch or pedals of a footswitch.
4-7
WARNING
For simultaneous connection of two electrode handles to both monopolar connecting sockets 6
and 7, electrode handles (particularly if they look alike) must be laid down in such a way that
there can be no mix-up. In case of doubt, a trial activation of the unit should be performed
without contacting the patient with the active electrode.
CAUTION
When using pointed bipolar coagulation forceps, the tips can be thermally damaged due to electric
currents that are too high. To prevent this, it is recommended that the power limitation be set as
low as possible and/or make certain that the tips of the bipolar coagulation forceps do not touch
one another.
9 Safety field
High-frequency surgical units of the ERBOTOM ICC series are equipped with various safety
devices to protect the patients and users.
WARNING
If both a dual-pedal footswitch and a single-pedal footswitch are connected to the unit, the
AUTO CUT, AUTO COAG and AUTO BIPOLAR function fields can, for example, be activated
via the corresponding pedals without further changeovers on the unit.
4-8
13 Volume of the acoustic signal
The volume of the acoustic signals can be adjusted with this knob.
This does not apply to warning signals which must always be sufficiently loud.
WARNING
An important purpose of this acoustic signal is to protect the patients and personnel from burns
due to unintentional activation of the high-frequency generator (for more information, see Chapter
3.1.2, Unintentional activation of a high-frequency generator).
Always set up the unit in such a way that acoustic signals are easily heard from this speaker. The
volume of the acoustic signals is set at the factory.
15 Power connection
This high-frequency surgical unit must only be connected via the power cord supplied by the
unit manufacturer or one of these of equal quality, which bears the national test symbol, to
correctly installed hospital grade power sockets. Here, for reasons of safety, no multiple sockets
or extension cords must be used if possible. If their use is unavoidable, they must be equipped
with a correctly functioning grounded connector.
16 Power fuses
The unit is secured with two fuses. If these fuses fail, an authorized technician should inspect the
unit for possible errors before putting back into operation. When replacing a power fuse, be
aware of the fuse value indicated on the unit’s rating plate.
4-9
4.3. Description of the safety features
The ICC 300 is equipped with the following safety features:
4.3.1 OUTPUT ERROR = Automatic monitoring of unit-related output error
4.3.2 TIME LIMIT = Automatic monitoring of the time limit
4.3.3 NESSY = Neutral Electrode Safety System
4.3.4 Protection against operating error
Deviations in the HF output parameters from the currently set HF output parameters on the ICC
can only result from loads which have too low a resistance, e.g. coagulation electrodes that are
too large, a short circuit between the active and neutral electrode, or due to an error in the unit.
4-10
4.3.2 Time limit
With normal use, a high-frequency generator is only activated
briefly for performance of an incision or a coagulation by
fingerswitch, pedal or AUTO START. This generally lasts only
a few seconds.
WARNING
For reasons of safety, a change in the automatic limitation of the maximum time limit must only
be made if all users of this unit are informed properly and in good time about this change.
In addition, a change in the automatic limitation of the maximum time limit must be properly
documented, for example in the medical product logbook of the respective unit.
4-11
4.3.3 NESSY
The units in the ERBOTOM ICC model series are equipped
with a Neutral Electrode Safety System (NESSY), which
monitors both the electric connection between the unit and
neutral electrode as well as the correct application of the neutral
electrode on the patient.
When using neutral electrodes with only one contact surface, only
the electric connection between the unit and neutral electrode is
automatically monitored. If this connection is sound, the green
NESSY signal (LED) is illuminated and all operating modes can
be activated. If this connection is interrupted, the green NESSY
signal (LED) is not illuminated and the monopolar operating modes
cannot be activated. If an attempt is made in this condition to activate
a monopolar operating mode, the red NESSY signal (LED) is
illuminated and a warning signal is heard at the same time.
When using neutral electrodes with two contact surfaces, not only
the electric connection between the unit and neutral electrode is
automatically monitored, but also the application of the neutral
electrode on the patient. Here the electric conductance between the
two contact surfaces on the neutral electrode and the skin of the
patient is constantly measured automatically and compared with
the intensity of the high-frequency current that flows through the
neutral electrode.
If the intensity of the high-frequency current is greater than is permissible at the respectively
measured conductance, NESSY then produces visual and acoustic warning signals and the operator
should only continue to use the high-frequency surgery if an incision or hemostasis has absolute
priority. If the measured conductance between the neutral electrode and the patient is too small,
monopolar operating modes cannot be activated.
The diversity of neutral electrodes models for high-frequency surgery is very large. The ideal
neutral electrode, optimal for all applications, does not yet exist. To ensure the user a large
degree of freedom in the selection of the best suited neutral electrodes for his/her purposes,
NESSY is a flexible Neutral Electrode Safety System that can be adapted optimally to the neutral
electrodes selected by the user. For appropriate advice and adaptation to suit requirements, please
contact your local Erbe office (see Chapter Addresses).
4-12
WARNING
For reasons of safety, a change to NESSY may only be made if it has been properly ensured that
all users of this unit are informed in good time about this change. In addition, a change to
NESSY must be properly documented.
When using dual-surface neutral electrodes, NESSY also monitors the application direction of
the contact surface relative to the direction of current flow. Since the high-freqeuency current is
generally not distributed evenly over the contact surface of the neutral electrode, but rather can
be greater at the proximal corners or edges to which the current flows than at the distal corners or
edges, attention should always be paid during application of neutral electrodes that the current
flows toward the long edge.
NESSY compares the intensity of the two partial currents I1 and I2 of the high-frequency current
IHF, which flow through the two partial surfaces of the neutral electrode. If the partial currents I1
and I2 deviate from one another, the red NESSY signal is illuminated. If the partial currents
deviate extremely from one another, the red NESSY signal is illuminated and at the same time
the NESSY warning signal is heard, and the HF generator is automatically switched off.
4-13
Correct application
The correct application must be observed not only for divided, but also for undivided neutral
electrodes.
WARNING
Before the neutral electrode is applied to the patient’s body, a check must be made as to whether
the green NESSY signal (LED) does not light when using a neutral electrode with two contact
surfaces.
The female connector beneath the front panel contains all the connecting sockets for the applied
part.
These connecting sockets are designed in such a way that only plugs from intended accessories
can be inserted (provided that only accessories recommended or supplied by the manufacturer
of the unit are used).
You may connect three instruments at the same time to the ICC. For reasons of safety, these can
however only be used alternately. Only one socket ever carries HF voltage.
Each time after switching on the power switch, an automatic test program is started within the
unit which recognizes and signals the following errors in the operating controls for the unit and
for accessories connected to the unit:
1. If a key on the front panel is shorted or pressed due to an error when the power switch is
switched on, this error is indicated acoustically and by an Error Number after the power
switch has been switched on.
4-14
2. If a key on the electrode handle is shorted or bypassed at low resistance due to an error
(e.g. by moisture in the electrode handle) or pressed while the power switch is switched
on, this error is signaled acoustically and indicated by an Error Number after switching on
the power switch.
3. If a footswitch contact is shorted due to an error, a pedal sticks or a pedal is pressed while
the power switch is switched on, this error is indicated acoustically and by an Error Number.
CAUTION
Every function field can only then be activated if it has been completely set. If an attempt is
made to activate a function field which has not or not completely been set, the unit produces an
intermittent acoustic warning signal and indicates this operating error by illumination of the
triangle symbols on the corresponding function field.

red warning signal and four warning tones are given after each activation of the HF generator.
In this condition, the unit must continue to be used only in case of emergency.
C = In this range, Rü is greater than 120 ohms. The HF generator cannot be activated. After
every activation attempt, a red warning signal and warning tones are given.
5-22
6 INSTALLATION
The unit is used in rooms in which personnel can pick up electrostatic charges, for example in
rooms with electrically nonconductive floors, thus touching the front panel of the units can lead
to a brief illumination of light diodes or seven-segment displays due to discharge of an electrostatic
charge. However, this occurence does not change the settings on the front panel.
ICC model series units are equipped with a potential equalization connector on the unit back
panel according to DIN 42 801. In this way, the units can be connected via a potential equalization
line to a potential equalization terminal at the set-up location.
WARNING
Footswitches are used within the potentially explosive area nevertheless and must therefore be
designed as explosion-protected.
6-1
6.6 Protection against moisture
ICC model series high-frequency surgical units are protected against the penetration of moisture
in accordance with EN 60 601-2-2 . In spite of this, these units should not be set up in the
vicinity of hoses or containers which contain liquids. Liquids should not be placed above or
even on the unit. Only those footswitches may be used which are watertight in accordance with
EN 60 601-2-2 Sec. 44.6 aa. Only those electrode handles with key switches must be used which
conform to
EN 60 601-2-2, Sec. 44.6 bb.
6.7 Cooling
ICC model series units must be set up in such a way that free air circulation around their housing
is ensured. For that reason, set-up in confined corners, shelves etc. is not permissible.
6.8 HF interferences
High-frequency surgical units intentionally generate high-frequency voltages and currents. It
must therefore be taken into consideration during set-up and operation that other electromedical
equipment may be subjected to functional interference.
For combination of an ICC with an Argon Plasma Coagulation unit, the instruction manual for
the Argon Plasma Coagulation unit must also be precisely observed.
The unit’s original packaging should be retained during the guarantee period so that the unit can
be returned in the original packaging if this becomes necessary.

6.11 Custom adaptation of the maximum time limit
In consideration of the risk of thermal tissue damages due to unintentional switching on of an
HF high-frequency generator, an unintentionally switched on HF generator should be switched
off again as soon as possible automatically. Since the unit cannot automatically distinguish between
intentional and unintentional switching on of an HF generator, the automatic switching off of an
HF generator must not occur too quickly, because this would impair the operator during cutting
and/or coagulation. Since the risk of thermal tissue damage varies greatly among the various
operating modes, the units of the ICC model series can adapt and store the maximum time limit
for each operating mode and in each storable program via the test program No. 10 of at least 3
sec. to a maximum of 900 sec.
5. By pressing the Ý or ß key beneath the respective display, the maximum time limit for
each function field can be custom adjusted from 3 to 900 seconds.
6. By pressing key 2.1, Test program 10 can be deactivated and the set maximum time limits
are stored.
7. It is possible to end the Test mode by switching off the power switch.
WARNING
For reasons of safety, a change in the automatic limitation of the maximum time limit must only
be performed if all users of this unit are informed properly and in good time about this change.
In addition, a change in the automatic limitation of the maximum time limit must be properly
documented.

6.12 Versions of Forced Coagulation
For Forced coagulation, the ICC generates brief voltage pulses with a high peak voltage. In this
way, an effective hemostasis is achieved even with very small-surface electrodes, such as with
TUR resection loops or laparoscopic retractors. However, these voltage pulses can cause more
or less intensive disturbances in other electronic equipment, such as in video monitors. The
Forced coagulation of the ICC can therefore be adapted via Test program 12 in regard to the
maximum adjustable peak value of the voltage pulses according to the respective application
purpose. Four different versions of Forced coagulation are available for selection:
Version 2
In this version, the peak value of the voltage pulses continuously increases to 2,300 Vp as a
function of the power limitation in the range of 1 watt to 80 watts.
Version 3
In this version, the peak value of the voltage pulses increases continuously to 2,300 Vp as a
function of the power limitation in the range of 1 watt to 30 watts. Above 30 watts power limitation,
the peak value of the voltage pulses is limited to a maximum of approx. 2,300 Vp.
Version 4
In this version, the peak value of the voltage pulses increases continuously to 2,600 Vp as a
function of the power limitation in the range of 1 watt to 30 watts. Above 30 watts power limitation,
the peak value of the voltage pulses is limited to a maximum of approx. 2,600 Vp.
WARNING
If Version 2, 3 or 4 is stored in memory, the unit briefly displays the current version every time
after the power switch is switched on. Standard version 1 is not displayed.
In addition, any change of the version of Forced Coagulation must be properly documented.

6.13 Basic setting and custom programming of the basic setting
If the unit is briefly (approx. 15 s) switched off and on again, the previous setting on the front
panel appears and the unit can be used again immediately. If the unit is switched off for longer
and switched on again, a freely programmable basic setting for the front panel appears, whereby
all displays 2.3, 3.6 and 4.3 blink and the unit cannot be activated until this basic setting is
confirmed by pressing any key. Then the displays are continuously illuminated and the unit can
be used immediately in this basic setting. If necessary, all settings on the front panel can now be
changed. After switching the unit off and on again after a longer period, the basic setting appears
again. If this basic setting proves to be inappropriate for the intended use of the unit, it can be
individually changed as follows.
On display 2.3 appears “ Pr“ and on display 3.6 appears “ 1“, i.e. Test program 1 for
changing the basic setting has been called up.
3. Press key 2.1. This activates Test program 1. The last stored basic setting appears. If however
no basic setting has been programmed by the user, “ —“ appears on displays 2.3, 3.6. and
4.3.
5. By switching off the unit, this front panel setting is automatically stored as the new basic
setting and appears automatically after every longer (approx. 15 s) period the unit is switched
off and on again.
6-5
The unit is equipped with a specific front panel basic setting. The specific basic setting is defined
at the factory and cannot be changed by the user. This specific basic setting only appears if the
basic setting freely programmable by the user is lost due to an error. For the ICC 300 unit, the
following specific basic setting is defined at the factory:

7 CLEANING AND DISINFECTION OF THE UNIT
We recommend a spray or wipe-down disinfection. However, the information from the disinfectant
manufacturer absolutely must be observed here.
WARNING
If cleaning or disinfection of the unit with flammable or explosive agents unavoidable, this must
be completely evaporated from the unit before switching on the unit.
Use no alcohol or disinfectant products with an alcohol base. The surface coating on the front
plate may become detached.

8 PERFORMANCE CHECKS
Before every application, the user should check the functional efficiency of the unit and the
accessories. The ICC is equipped for this with various automatic performance checks that, each
time the power switch is switched on, are performed briefly and then signal and display recognized
errors. However, not all possible errors are automatically detected and displayed.
1. If a key on the front panel is depressed or shorted out due to an error once the power switch
is switched on, this error is signaled acoustically after switching on the power switch and
indicated by an error number.
2. If a key on the electrode handle is shorted out or bypassed at low resistance (e.g. due to
moisture in the electrode handle) due to an error or depressed while the power switch is
switched on, this error is signaled acoustically after the power switch is switched on and
indicated by an error number.
3. If the contact of a footswitch is shorted out due to an error or if a pedal is stuck or a pedal
is depressed while the power switch is switched on, this error is signaled acoustically and
indicated by an error number.

8.3 Automatic error documentation
The ICC is a equipped with an automatic error recognition, error signaling and error documentation
device. Errors are detected which are present or occur during switching on of the power switch,
during the Self Check after switching on the power switch, during tests or during activation of
the unit and/or of accessories connected to the unit. The smaller errors recognized by the unit are
only signaled visually, larger errors are signaled visually and also acoustically. The various errors
recognized by the unit are assigned error numbers. If an error occurs, it is not only immediately
signaled visually and/or acoustically, but also the corresponding error number is stored in the
unit, where it then also remains stored if the unit is switched off. The last 10 error numbers can
be called up as follows via Test program number 2 at any time.
a) Press key 3 while the unit is switched off and switch on the power switch.
· Pr (Program) appears in the AUTO CUT display
· 1 appears in the AUTO COAG display
d) In the error list, the various errors for the error numbers are described.
e) By pressing keys 8 or 9, the 10 error memory locations available can be called up.
· The number of the respective error memory location appears in the AUTO COAG display.
· The respective error number appears in the AUTO BIPOLAR display.
f) By pressing key 7, the error numbers in all error memory locations can be deleted.
