6.2.1 Adjustable sound
It is possible to adjust the sound level in the speech unit with a trim pot. The trim pot is hidden
behind the small plastic protection part covering and protecting the key pad tail. Remove
carefully the plastic part and use a small screw driver to increase or decrease the sound. The
sound is increased by turning the trim pot counter clockwise and the sound is decreased by
turning it clockwise. Normally the factory setting is enough for most types of lift cars.
6.2.2 Frame mounting
Mark and pre-bore the holes for the speech unit frame at suitable position according to en-
closed drill template. Drill the holes for the modular cable to reach modular contact on speech
unit. The modular cable cannot be led between the keyboard and the lift wall because the dis-
tance between the keyboard and the wall is too small when the speech unit is screwed into
the frame. This requires the hole for the modular cable to be drilled next to those of the edges
of the frame, see the enclosed drill template.
Mounting of speech unit in the enclosed frame
6.2.3 Recessed mounting
There is also a possibility to mount the speech unit without frame, so called recessed mount-
ing. Drill a hole in the centre of the selected place and then make a hole with a 86 mm rotary
hole saw or drill. See the enclosed drill template. Mark the holes for the mounting screws and
pre-bore.
6.2.4 Mounting behind Car Operating Panel (COP)
There is a special version of the speech unit which is specially designed for mounting behind
a button and display plate. This alternative is only possible if there is already a prepared
space for a lift phone behind the button & display plate. Since the design of the display may
vary, we are not able to give exact mounting instructions here. Keep in mind that the micro-
phone hole must be aligned with a hole in the display plate. It might become necessary to drill
a new hole. For the best sound quality, the distance between the speech unit front plate and
the display plate should not exceed 1 mm.
Make sure that you do not saw or drill in existing cabling when you make holes!
