5.2 System test
The system test starts automatically after power-on and takes about 5
seconds. During this period, the background colour changes from red to
yellow and eventually to green.
In addition, the device emits two consecutive audio signals: the first signal
at a volume level of 50%, the second signal at the last selected volume
level. For details, please refer to chapter 5.6.1 Alarm volume.
Note It is possible to switch off all audible alarms. If the audible alarms
were switched off the last time the device was in use, only a
single tone will be emitted during the system test.
The Alarm OFF LED is switched on and off once during the system test as a
functional check.

system are checked during the system test, as
described above:



audible alarm and alarm volume

Do not use the device if any of the elements does not
