Improper mounting may deteriorate the intercom waterproofness and
water may damage the electronic part.
Make sure that all 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..
Make sure that the bases are levelled properly to avoid water leakage and
electronic damage.
