3.3. Activation and alarm signals in monopolar and
bipolar mode
The activation and alarm signals are emitted at volume level 19. The
mnimum volume is level 16. If required, the volume of the activation
signals can be adjusted for a louder environment. The alarm sound
cannot be changed.

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
function.
3.5.2. Cyclical test during operation
During operation, safety-relevant functions and signals will be tested
cyclically. If errors are detected, the HF generator will shut itself off. An
error message appears on the display. For further information, see
Detecting and correcting errors, Page 64.
