Adhesive strip mounting
For mounting the window / door contact with the sup-
plied adhesive strip, please proceed as follows:
•
Attach the double-sided adhesive strip to the
back of the electronic unit (B) and press the elec-
tronic unit onto the desired position of the win-

Make sure that the mounting surface is smooth,
solid, non-disturbed, free of dust, grease and sol-
vents and not too cold to ensure long-time ad-
herence.
