Cleaning external surfaces
To clean the compact disc recorder, wipe with a soft, dry cloth. For stubborn dirt, wet a
soft cloth with a mild detergent solution made by diluting one part detergent to 5 or 6
parts water, wring well, then wipe off the dirt. Use a dry cloth to wipe the surface dry.
Do not use volatile liquids such as benzene and thinner which may damage the
surfaces.
Moving the unit
If you need to move the unit, first switch it off and unplug from the wall outlet. Never
lift or move the unit during playback or recording—CDs rotate at a high speed and
may be damaged.
CD lens cleaner
The compact disc player's pickup lens should not become dirty in normal use, but if
for some reason it should malfunction due to dirt or dust, consult your nearest
Pioneer authorized service center. Although lens cleaners for compact disc recorders
are commercially available, we do not recommend using them since some may
damage the lens.
Tape head cleaner
To maintain the recording/playback quality of the tape deck, use a commercially
available wet-type cassette head cleaner. Avoid using dry-type cassette head cleaners.
Be careful: Some cassette head cleaners are not designed to work with auto-reverse
decks and may become jammed in the mechanism — ask your Pioneer authorized
service centre for details.
After using the head cleaner, leave the unit for 2–3 minutes before playing a tape. This
will give any excess cleaning fluid a chance to dry.
Demagnetizing the tape head
The recording/playback head in the tape deck gradually becomes magnetized after
long periods of use. Playback and recording quality will suffer as a result, with a lack
of treble and increased noise. To avoid the problem, we recommend using a head
demagnetizer at regular intervals. These are available from any good audio dealer.
When using a head demagnetizer, be sure to turn the volume right down and unplug
any headphones to avoid damaging the unit or the speakers. For further details, refer
to the instructions that came with the head demagnetizer.
