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 receiver turned on for a few hours
until the moisture evaporates.
How to handle discs/SD cards
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.
SD cards are precision products. DO NOT
impact, bend, drop, or wet them.
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.

conventional record cleaner, spray, thinner,
benzine, etc.) to clean discs.

New discs may have some rough
spots around the inner and outer
edges. If such a disc is used, this
