Looking after BeoSound 9000
Surfaces
Before you start cleaning BeoSound 9000, we
recommend that you open the glass door and
then switch off the mains. 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.
CD mechanism
The circuit controlling the movement of the
CD carriage has a built-in safety function
which protects your fi ngers, etc. from being
hit by the fast moving carriage. This circuit
depends on light/refl ections, and works via
opto-coupling devices built into the two small
'pegs' (A). When the glass door is opened, or
if something interrupts the light-circuit, the
carriage slows down in speed, and fi nally
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 refl ections
which may be interpreted by the safety function
in a wrong way.
So, in order to prevent malfunction 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 BeoSound 9000,
remember also to clean the inner surface of the
glass door.
