Function test
Carry out the function test once a month:
1. Press the test button for approx. 3-sec. If the signal sound is emitted, the
smoke detector operated correctly. If no signal sound is emitted, replace
the battery.
2. Carry out the function test again. If no signal sound is emitted again, the
smoke detector is defective and has to be replaced with a new one.
