To keep discs clean

A dirty disc may not play
correctly. If a disc does become
dirty, wipe it with a soft cloth
in a straight line from center to
edge.
• Do not use any solvents (for example,
conventional record cleaner, spray, thinner,
benzine, etc.) to clean discs.

To play new discs

New discs may have some
rough spots around the inner
and outer edges. If such a disc
is used, this unit may reject the
disc.
To remove these rough spots, rub the edges
with a pencil or ball-point pen, etc.
Do not use the following discs:
Single CD (8 cm disc) Warped disc
Sticker and sticker
residue Stick-on label
Unusual shape
C-thru Disc
(semitransparent

Maintenance

How to clean the connectors

Frequent detachment will deteriorate the
connectors.
To minimize this possibility, periodically wipe
the connectors with a cotton swab or cloth
moistened with alcohol, being careful not to
damage the connectors.

Moisture condensation

Moisture may condense on the lens inside the
unit in the following cases:
• After starting the heater in the car.
• If it becomes very humid inside the car.
Should this occur, the unit may malfunction.
In this case, eject the disc and leave the unit
turned on for a few hours until the moisture
has evaporated.

How to handle discs

When removing a disc
from its case, press down
the center holder of the case
and lift the disc out, holding
it by the edges.
• Always hold the disc by the edges. Do not
touch its recording surface.
When storing a disc in its case, gently insert
the disc around the center holder (with the
printed surface facing up).
• Make sure to store discs in cases after use.
