Ensure each time you switch on that two different acoustic signals sound one after the
other and that the yellow and red LEDs come on at the same time.

alarm (power supply failure alarm):
Start up the therapy device. Now take the power cord out of the socket. The internal
battery assumes power supply, the two buzzers sound and the yellow LED comes on.

Oxygen supply
Caution!
If a compressed gas system is used instead of an oxygen concentrator, an
overpressure valve must be fitted.
Note:
A function check can only be performed on the oxygen supply if the oxygen supply
has been activated by the doctor beforehand (flow meter or oxygen concentrator).
In order to carry out a function check on the oxygen supply, proceed as follows:
1. Start up the therapy device.
2. Connect the oxygen source to the therapy device and start it up.
3. At the oxygen source, set the oxygen flow to the value prescribed by the doctor.
4. Select one of the following procedures depending on whether or not you are using an
oxygen sensor.
With an oxygen sensor
Ensure that the oxygen sensor is connected correctly and has been calibrated beforehand.
The oxygen supply is functioning properly if an oxygen concentration of > 21 % is
shown on the display and the oxygen flow rate prescribed can be set on the oxygen
source.
Without oxygen sensor
The oxygen supply is functioning properly if the oxygen flow rate prescribed can be set
on the oxygen source.
