Caution
Before starting the mechanical installation on a selected place, make
sure carefully that the preparations associated with it (drilling, wall
cutting) cannot damage the electrical, gas, water and other existing
wires and pipes.
The warranty does not apply to the product defects and failures arisen
as a result of improper mounting (in contradiction herewith). The
manufacturer is neither liable for damage caused by theft within an area
that is accessible after the attached electric lock is switched on. The
product is not designed as a burglar protection device except when
used in combination with a standard lock, which has the security
function.
When the proper mounting instructions are not met, water might get in
and destroy the electronics. The intercom circuits are constantly under
voltage and water infiltration causes an electro-chemical reaction. The
manufacturer's warranty shall be void for products damaged in this way!
Caution
Make sure that the diameters of the dowel holes are accurate. If the
diameters are too large, the dowels may get loose. Use the mounting
glue to secure the dowels if necessary.
Make sure that the depths of the dowel holes are accurate!
Do not use low-quality dowels to avoid their falling out of the wall!
Surface mounting always poses a problem where the installation is
exposed to potential vandalism (such as public garages, etc.). In this
case, use steel anchoring elements instead of the dowels and screws
included in the delivery.
Make sure that the mounting surface is flat with a maximum inequality of
0.5 mm. (e.g. prefabricated boards, glass, cut stone, etc.). If this is not
the case, level the wall surface.
Any intentional mechanical damage to the device (drilling, main unit
tampering, etc.) results in a loss of warranty.
