Additional Information

Taking care of your system

To clean this unit, 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 or thinner which may damage the
surfaces.

Disc lens cleaner

The disc 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 CD players are commercially available, we do not
recommend using them since some may damage the lens.

Taking care of your discs

When holding discs, take care not to leave fingerprints, dirt or
scratches on the disc surface. Hold the disc by its edge or by the
center hole and edge. Damaged or dirty discs can affect playback
performance. Take care also not to scratch the label side of the
disc. Although not as fragile as the recorded side, scratches can
still result in a disc becoming unusable. (A)
Should a disc become marked with fingerprints, dust, etc., clean
using a soft, dry cloth, wiping the disc lightly from the center to
the outside edge as shown left. If necessary, use a cloth soaked in
alcohol, or a commercially available CD cleaning kit to clean a
disc more thoroughly. Never use benzine, thinner or other
cleaning agents, including products designed for cleaning vinyl
records.
• Wipe lightly from the center of the disc using straight
strokes. (B)
• Don't wipe the disc surface using circular strokes. (C)

Storing discs

Although CDs are more durable than vinyl records, you should
still take care to handle and store discs correctly. When you're not
using a disc, return it to its case and store upright. Avoid leaving
discs in excessively cold, humid, or hot environments (including
under direct sunlight).
