completion – after electric
installation!
Insert the intercom in the hole keeping it in the
vertical position.
Loosen the four clamp screws one after another
and then retighten them slowly. They will turn
aside automatically and start moving forwards in
their slots. You need about
to tighten 10 turns
the clamps completely. You can perfect the
vertical position before final tightening of the
screws.
We do not recommend you to insert the button
tags now.
Replace the stainless steel front panel fixing it with
the stainless steel screws you unscrewed in step 2.
Tip
If this is your first plasterboard installation,
check the function of the intercom side
clamps. Loosen and then re-tighten the
clamp screw to see how it turns
automatically and starts moving forwards in
its slot. Remember to return the clamp into
the original position after the check!
Caution
Check the plasterboard wall and room
interior pressure values (caused, e.g., by
overpressure ventilation). If the difference
between the values is too great, separate
the intercom using, for example, the
mounting box enclosed and seal the cable
passage to avoid loudspeaker damage.
