Note: For uneven walls we recommend using the adapter for the anti-removal wall contact.
Remove the front cover of the sensor by unscrewing the Allen screw using the Allen key
provided. [Fig. 3.1] The cover can then be swung down out of its groove and lifted off. [Abb.
3.3] If this is not possible, use the special plastic tool provided in the scope of delivery [Fig.
3.4] to loosen the cover by carefully levering sideways to the left and right without
damaging it. [Fig. 3.2]
