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!
Check the plasterboard wall and room interior

ventilation). If the difference between the
values is too great, separate the intercom

and seal the cable passage to avoid loudspeaker
damage.
