2. Touch the Tests... button.
3. Touch the System test button.
The checklist opens and the breathing system pressure is displayed in the lower
left-hand corner.
4. Press the O
2+ key and keep it pressed until the displayed breathing system
pressure no longer rises.
5. Release the O
2+ key.
6. Wait until the pressure stabilizes between 15 and 30 hPa. If the pressure drops
further, the hose is leaking.
7. Exit the system test again. To do this, touch the Cancel button.
For leaking hoses, the complete leakage test can be used to determine how large
the leakage value is and whether the hose can continue to be used.
