3.3. Activation and alarm signals in monopolar and
bipolar mode
The activation and alarm signals are output at volume level 1. The
minimum volume is level 1. The volume of the activation signal should be
increased as necessary for use in relativey noisy surrouondings. The
maximum volume is level 10. The alarm tone is not adjustable.

3.5. Monitoring functions
3.5.1. Self-test
When the HF device is switched on, it runs a self-test that checks the
operating elements, acoustic signal, microprocessor and hardware for
proper operation. If errors occur, see section Detecting and correcting
faults, page 51.
3.5.2. Cyclical test during operation
During operation, safety-relevant functions and signals are tested
cyclically. If errors are detected, the HF generator will shut itself off. An
error message appears on the display. For further information, see
section Detecting and correcting faults, page 51.
