During the self-recognition it is important that nothing (objects, people, etc.) is at a
distance of less than 1 meter from the detector.
Once the self-recognition has finished, the detector enters the "Anti-masking test"
mode for 10 minutes. During these 10 minutes if you try to mask the detector for
more than 20 seconds, an hazard signal is issued.
The detector automatically exits the "Anti-masking test" mode when 10 minutes have
passed.
WARNING! If the anti-masking function is active, the self-recognition
procedure and anti-masking test are activated again each time you remove
the front cover of the detector and you lay it back.
