Version B
Hang the wall mounting frame on the hook in the upper part and then screw it tight in
the bottom part.
Most Frequent Mounting Errors
At first, mount the metal bolts, level the bases on an even surface and tighten the
screws.
The examples in the figures below show incorrectly assembled bases. This happens, in
particular, where the screws are tightened first.
Caution
Improper mounting may deteriorate the intercom waterproofness and
water may damage the electronic part.
Make sure that all the holes are filled with some waterproof material – the
top part, around the cables and the screws.
Use silicone or some other sealant to seal the box against the wall if
uneven to avoid water leakage and wall damping.
Caution
Make sure that the bases are levelled properly to avoid water leakage and
electronic damage.
