entering the alarm.
Start-up
1. Insert the supplied batteries into the battery compartment with the correct
polarity. The warning tone sounds, the display shows the numbers from 000 to 999
and all three LEDs flash alternately. At the end of the warm-up phase, the LEDs and
display go out.

3. Then enter the current date (date of installation) on the rear label of the alarm

Testing the device electronics
Check the function of the CO alarm by pressing the test button for 5 seconds. To
protect your hearing, keep away from the device!
The alarm sounds four times and the red LED (alarm light) flashes four times.
This does not signalise that CO is present in the room; it is a confirmation that the
alarm is functioning properly.
Test the alarm function after installation and after every battery change without fail
(wait about 30 seconds after establishing the battery contact). A regular weekly test
is also recommended.
For wall installation: set the alarm
on the screws with the rear side of
the device facing downwards and
lock it into place.
