Connecting the power supply
Risk of death by electric shock!
►
Connect the product only to a grounded power
supply.
DANGER
►
Set up the device in such a way that disconnect-
ing the power cord is straightforwardly possible.
Note
Before putting the device into operation, ensure that the voltage stated on
the device connector corresponds with the mains voltage. To change the
setting, see Presetting the correct voltage.
The HF device GN300 may only be operated with an alternating current of
50-60 Hz. The mains voltage must be between 100 V and 120 V or
between 220 V and 240 V. The voltage is preselected on the device con-
nector on the rear side of the device. Insert the power cord only in a prop-
erly mounted schuko power socket (for this see VDE 0107).
To prepare the device for operation, proceed as follows:
►
Connect the HF device to the mains voltage using a power cord (LED 5
illuminates).
►
Connect instrument cables to the corresponding outputs.
►
Connect foot switch to socket 36.
►
Press key 7 (LED 5 and LED 6 illuminate).
The HF device is ready for operation.
Note
The isolation of the power cable from the device must also be treated as
secure isolation from the mains in the sense of the IEC norm. When aligning
the device, ensure that an isolation of the mains plug is possible without
any problems.

Function checks
■
After connecting the device to the mains voltage, the green LED 5
should illuminate.
■
After pressing the "Device on/off" switch 7, LED 6 illuminates. All LEDs
and segments of the dosage displays illuminate for a short period of
time and the acoustic power indicator (buzzer) is activated.
■
After a short waiting time of approx. 5 seconds, during which the inter-
nal checks are carried out, the selection menu appears for entering the
desired neutral electrode type; (also see "Preselection of the neutral
electrode type").
■
If, during the switch-on process, a neutral electrode is connected, the
error message "Er 01" appears. If this error status is removed by sepa-
rating the neutral electrode from the device, the neutral electrode type
can be changed.
■
The neutral electrode selection pane will close after a further 3 sec-
onds; the device will then use the most recent settings and can be
operated and activated from that point onwards.
■
By pressing the "+" key, the dosage displays must be increased until
reaching the defined maximum values.
■
By pressing the "-" key, the dosage displays must be decreased until
reaching the defined minimum values.
■
The storage functions are also described in other sections, see Saving
the device settings and see Viewing the stored device settings.
►
Connect foot switch to socket 37 and press it; upon doing so, the
acoustic and visual power indicators should respond.
Dosage setting
By pressing the "+" or "-" keys, the dosage values are set to the desired
value. The operating mode-dependent minimum and maximum values
should be taken from the following table:
Operating mode
Bipolar CUT
Bipolar COAG
Monopolar CUT M 1
Monopolar CUT M 2
Monopolar CUT M 3
Monopolar CUT M 4
Monopolar COAG normal
Monopolar COAG spray
Storage function
►
As a test, save a preselected device setting and open it again, see Sav-
ing the device settings and see Viewing the stored device settings. The
values should remain set, even after a long period of separation from
the mains.
Control function
As described in more detail below, see Protection against faulty operation,
the operation and device-internal functions are continuously monitored
for possible errors. Detected errors are shown on the display as specific
error codes (Er XX). Pressing two or more keys at the same time therefore
displays the error code "Er 06".
