ALARM FUNCTIONS OF THE DEVICE
POWER FAILURE
If a power failure at night would go unnoticed as a result the patient would
breathe used air from the therapy tube all night. To avoid this the device is
equipped with an alarm mechanism that warns you if power or a fuse fail
at night. You will be woken up with an acoustic signal so you can take the
mask off your face and breathe fresh air. The alarm is turned off by push-
ing the on/off key. After power supply is re-established the motor starts
automatically and the display will show the following message:
!0/./1.%*!
+3!.%(1.!
Checking the power failure function
To check the power failure alarm, the device must have been con-
nected to the power cord and turned on for at least half an hour.
Use the device with running blower and then pull the power plug out of
the wall socket. Now the acoustic warning signal should sound. Check
once a month if the signal sounds long enough (reference value: at least
3 minutes). After pushing the on/off key or turning on the power supply
again the signal will stop.
MASK ALARM
This alarm function is activated only if the automatic function is turned to “OFF”
or “Start”. If the mask has slipped off your face or if the tube is pulled off the
device, the device is not turned off automatically, but emits a visual and audible
alarm. The alarm is silenced after pressing the on/off key or eliminating the leak.
Check Mask Alarm
Use the device with running turbine in the manual mode (automatic func-
tion “OFF” or “Start”). The mask is open but not applied to your face. After
a short time, an audible signal is emitted.
