Caution
Make sure that the dowel holes have the required diameter. If the
diameter is too large, the dowels may get loose. Use some suitable
building adhesive to keep the dowels in place.
Make sure that the hole depth is sufficient too! The dowel length is 50
mm and the screw length is 90 mm.
Remember that dowels of poor quality may easily get loose and fall out
of the wall!
Stainless steel screws are used for the assembly. 2N Helios IP Force

Other screws than stainless steel ones corrode soon and may
aesthetically deteriorate the surrounding environment!
Having removed the front panel, make sure that no dirt gets inside the
product (especially onto the sealing surface and microphone sound
guides).
Caution
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 damages caused by theft within an
area that is accessible after the attached electric lock is switched. 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. It is because the intercom circuits are under
continuous voltage and water infiltration causes an electro-chemical
reaction. The manufacturer's warranty shall be void for products
damaged in this way!
