Notes:
1. The speech module, as
well as the rear-mount-
ing loudspeaker and
microphone require suf-
ficiently large sound
inlet and outlet holes
(see also page 2).
2. Rear-mounting compo-
nents must be mounted
flush with the rear side
of the car operating
panel using a gasket
(important for good
sound quality). See also
note on page 2.
3. Keep the distance
between the micro-
phone and loudspeaker
as large as possible. See
also note on page 2.
4. For notes on mounting
BNOS MCT (machine-
room/car telephone),
BNOS UPS, BNOS hubs,
etc., refer to the corre-
sponding products.
