10 Alarms and error messages
10.1 General instructions
The device's alarm system is based on the concept of self-
preserving alarms. The device emits an alarm for as long as the
cause continues to exist. Once the cause of the alarm no longer
exists, the device no longer emits the alarm.
The device emits physiological and technical alarms. Every alarm
has a certain priority.
If more than one alarm is active, the device handles this as follows:
• Multiple alarms of different priorities: The device displays the
alarm with the highest priority. Alarms with a lower priority do
not appear until the higher-priority alarm is no longer active.
• Multiple alarms of identical priorities: The device displays the
alarms alternately.
• Technical alarms dominate and cannot be muted. Technical
alarms occur if ventilation is not possible with the device (e.g.,
in the event of a device fault, a supply pressure < 2.7 bar).
