Retrieve stored device settings
Press the desired storage button "1-4" 12.
The LED 13 over the pressed storage button lights up when the selec-
tion has been made successfully.
The stored dosage level and the stored settings are displayed and taken
over.
The dosage level can be changed, see Adjust the dosage. LED 13 no longer
lights up as there is no agreement with the stored value.
Activate HF output
Activate the HF output with the foot switch over the "automatic start-
ing" option with the coagulation forceps.
Activation is signaled acoustically with a tone generator. The pitch is
different for each operating mode. "Micro" corresponds to 725 Hz,
"Macro" 850 Hz.
The LED 9 "HF output active" lights up.
When activating the HF output, the HF device does not react to operation
with the membrane keyboard apart from the "Device on/off" button 3. The
HF device can therefore be switched off at any time. Likewise, the activa-
tion of the HF output is not possible as long as a membrane key is pressed.
Taking the HF device out of service
Press the "Device on/off" button 3 in order to switch off the HF device.
"Device ready for operation" LED 2 goes out.
LED 1 lights up, HF device is still ready for switching on.
Withdraw mains cable.
HF device is completely isolated from the power supply.

Protection against faulty operation

Continuous actuation of a key
If a membrane key is pressed for longer than 15 s, this is interpreted as
permanent contact and therefore as an error. The error code "F2" appears
in the display. This prevents, for example, that an object the presses acci-
dentally against an operating button remains unnoticed. The same error
report appears if a membrane key is already pressed when the HF device
is switched on. While an error code is being displayed, the activation of
the HF output is not possible.
If the cause of the error is remedied, normal work can then continue.
Multiple keys pressed
If two or more buttons are pressed at the same time, the error "F1" appears
in the display.
Locking mechanism
In order to prevent unwanted manipulation, no change of the device
adjustment is possible while the HF output is active.
Conversely, an activation of the HF output is also not possible during the
change of device settings.
When switching from foot switch to automatic operation and the reverse,
the foot switch must be deactivated and the two arms of the forceps must
not touch. When switching on the HF device, all membrane keyboards and
the foot switch must be disengaged.
If these conditions are not observed, the error message "F2" is shown in
the display.
Normal working or operation of the HF device is only possible after the
removal of the conditions causing the error.
Permanent activation
If the foot switch is activated for more than 30 s, or if a sticky contact or
a short circuit in the foot switch or its cable occurs, this is interpreted as
an error. Subsequently, the HF output is deactivated and the error message
"F3" for permanent activation is shown in the display.
When using the automatic starting: If the device is activated for longer
than 30 s by the automatic starting, the error message for permanent acti-
vation "F3" is also displayed and the HF output is deactivated. The cause
of the error message can hereby also be sticky forceps or a defective bipo-
lar cable.
If the cause of the error is removed (for example through the disengaging
of the foot switch), normal work can continue.
Activating the "Preparing for storage" button
If the "Preparing for storage" button 20 is pressed accidentally, the HF
output can not be activated.
There are three ways of returning to the normal operating mode:
Storing device settings in a memory.
Pressing the "Preparing for storage" button again 20.
After approx. 10 s, the HF device automatically returns to the normal
operating mode.
