High-frequency surgical device GN300
The foot switch is assigned to the corresponding generator using key 39.
If, for example, the foot switch is assigned to the bipolar part, the mono-
polar part can only be activated via the handpiece.
If the monopolar part then needs to be activated via the foot switch, the
pedal assignment must be changed via key 39. The current pedal assign-
ment is displayed via the signal lights 34 and 41.
The foot controls are Class AP devices. The foot control circuit is ignition-
safe and approved for operation in medical environments according to
IEC DIN/EN 60601-1.
The housing is constructed according to Protection Class IPX8.

Operating principle
The high-frequency surgical device GN300 is a microprocessor-controlled
device with the corresponding ease-of-use and extensive monitoring
functions.
It is operated using a cleaning-friendly membrane keyboard.
The device can be operated in the voltage ranges of 100 V~-120 V~
or 220 V~-240 V~ (+/-10 %). For selecting the voltage, see Presetting the
correct voltage.
The combination of bipolar and monopolar generators and the different
setting possibilities for cutting and coagulation mean that the device can
be used universally.
The precise dosage settings guarantee the optimal device setting in each
individual case.
Thanks to the in-built storage function, empirical values or individual
device settings can be viewed at the push of a button, see Saving the
device settings. The data saved remains in the device memory for a long
time, even when the device is switched off.
The device carries out a self-test every time it is switched on. Even during
operation and high-frequency output, all safety-relevant functions and
signals are tested at 10 millisecond intervals.
If disruptions or errors occur, the device immediately switches to safe
operating mode, i.e. the HF generator is deactivated and the correspond-
ing error code is displayed. This code makes it easy to distinguish whether
it is an operating error or a device error. Furthermore, a localized error
diagnosis is also possible see Troubleshooting list.

Power setting
For cutting work, the power setting primarily takes place via a variation of
the level of HF output voltage.
If the modulation index is set in a certain way, the duty cycle (t/T) will
remain constant for the entire dosage range.

When changing the modulation index, the resulting change to the duty
cycle is compensated by a change of the HF output voltage meaning that
the output voltage remains constant for the respective loads.
However, it should be noted that the respective maximum values of out-
put power are dependent on the set modulation index.
