Do not use alcohol or other
solvents to clean any part of
the BeoSound 9000!
Surfaces
Before you start cleaning the
BeoSound 9000, we
recommend that you open the
glass door and then switch off
the mains (just push the red
power switch button). In this
way all surfaces are accessible
for cleaning. Use a soft, dry cloth
to wipe dust off the BeoSound
9000. To clean the surfaces, we
recommend that you use a mild
window cleaner.
When you have finished
cleaning the BeoSound 9000,
remember to switch the red
power switch on again.
NOTE! Treat the glass door
with great care! If it cracks or
chips, or if it is damaged in any
other way, it must be replaced
immediately as it could other-
wise cause great bodily harm.
If the glass door should need
to be replaced, please contact
your Bang & Olufsen dealer.
CD mechanism
The circuit controlling the
movement of the CD carriage
has a built-in safety function
which protects your fingers,
etc. from being hit by the fast
moving carriage. This circuit
depends on light/reflections,
and works via opto-coupling
devices built into the two small
‘pegs’ (
A
). When the glass door
is opened, or if something inter-
rupts the light-circuit, the
carriage slows down in speed,
and finally comes to a halt.
Over time dust may build up
and thus reduce the light
emitted to and from the opto-
coupling devices. Dust particles
on the inside of the glass door
may also cause extraordinary
reflections which may be inter-
preted by the safety function
in a wrong way.
So, in order to prevent mal-
function of the safety circuit,
we recommend that you wipe
dust off the two pegs (
A
) on a
regular basis. Likewise, when
cleaning the surfaces of the
BeoSound 9000, remember also
to clean the inner surface of
the glass door.
