Operation
When the mask test is activated, the higher pressure set is
output for 30 seconds (8 hPa in the example).
1. Check that the mask is leaktight and adapt the head
strap if necessary.
2. To cancel the mask test before the 30 seconds have
expired, press the On/Off key.
The therapy device is now operational.
You can have current leakage displayed during therapy.
No leakage/low leakage: mask is perfectly positioned,
ensuring effective therapy.
Moderate leakage: mask is not perfectly positioned,
quality of therapy may be restricted.
High leakage: effective therapy is no longer possible. Re-fit
the mask.
If Softstart is pre-set, the Softstart indicator then lights up
and the start time appears in the display.
Current pressure is also shown in the display.
