6. If you use a roof module, fix its upper and
side edges to the wall using silicone glue as
shown in the figure to the right.
Keep the following outdoor mounting
principles:
 Always connect the backlight – it
serves to equipment heating.
 Water must not flow in along or around
the cables.
 Before closing the cover, carefully
check all wires inside the cover for
perfect closing.
 Make sure that all of the three
loudspeaker holder feet fit into the
board holes. A correct loudspeaker
position is necessary for a proper
function of the seal.
 Make sure that the silicone seal (tube on the upper face) is in place after
installation.
 Remember to tighten all of the four corner screws after electrical
installation to make the loudspeaker seal fit perfectly. Otherwise, water
might get into the electronic part! Recommended tool: cross-head screw
driver PH2.
Caution
 When the above mentioned precautions are not met, water might get in
and destroy the electronics. It is because the communicator 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!
