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
CD player in the following cases:
• After starting the heater in the car.
• If it becomes very humid inside the car.
Should this occur, the CD player may
malfunction. In this case, eject the disc and
leave the unit turned on for a few hours until
the moisture evaporates.
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 into its case, gently insert
the disc around the center holder (with the
printed surface facing up).
• Make sure to store discs into the cases after
use.
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 solvent (for example,
conventional record cleaner, spray, thinner,
benzine, etc.) to clean discs.
