All device alarms are evaluated during ventilation, in standby
mode and when the automatic patient detection function does
not detect a patient. An alarm is triggered when applicable.

Patient alarms are only evaluated during ventilation and when
the automatic patient detection function detects a patient. An
alarm is triggered when applicable.
System test
As a matter of principle, a system test must be carried out before the ventilator
is used.
Warning
Never carry out a system test if a patient is connected to the
device.
The system test ensures that all safety-related functions and components are
tested before the ventilator is used. The system test can be bypassed in the event
of an emergency.
If the system test was bypassed, the system cannot determine the correct values
of the currently used breathing circuit which are necessary for optimal compli-
ance and resistance compensation. In this case, the measurement values of the last
