To mount the unit, you need 4 electrically spot-welded (from the inner panel side)
M3
or
screws, a sufficiently perforated speaker area and a microphone hole. If needed,
M4
a high-quality double-sided foam self-adhesive tape can be used for installation on a
perfectly degreased surface.
Warning
Leave no gap between the lift control panel and the audio unit surface
to avoid acoustic speaker fault and acoustic speaker-microphone
feedback.
this type of audio unit
Do not use
otherwise than mounted on a
sufficiently large board. The acoustic properties of an uninstalled audio
unit cannot be guaranteed.
Separate Microphone Mounting
If the microphone is supplied separately on a 25 x 25 mm large board with self-
adhesive foil and with a cable, you can mount it easily behind any hole in the panel
(keep the minimum hole diameter of 5 mm or a group of smaller holes of the same
total area). Just glue the microphone directly onto the required place from behind (be
sure to degrease and clean the surface carefully before mounting!).
Requirements
The minimum distance between the speaker and microphone centres is 90 mm.
A lower distance may lead to acoustic feedback. A greater distance (within the
available 1m cable) does not matter.
Make sure that the glued-on microphone does not pick up (even partially!) the
acoustic pressure from the space behind the panel. Such sensing might result in
acoustic feedback since the speaker strongly radiates sound into the cavity
Separate Speaker Mounting
The speaker is equipped with a cable and can be separated from the electronics by
simply being slid out within the reach of the cables delivered (1 m). This option is
useful where there is not enough space for the whole electronic equipment. Fit the
loudspeaker according to the instructions below:
While gluing choose such procedures or adhesives that prevent membrane
damage by adhesives and volatile substances, or heat.
We recommend you to keep the speaker sealed to eliminate vibrations and
ensure electric insulation.
