Maintenance
To get the best performance of the unit, keep your discs and mechanism clean.
General Notes
In general, you will have the best performance by keeping
your discs and the mechanism clean.
• Store discs in their cases, and keep them in cabinets or
on shelves.
• Keep the disc trays closed when not in use.
To handling 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.
• Be careful not to scratch the surface
of the disc when placing it back in
its case.
• Avoid exposure to direct sunlight,
temperature extremes, and moisture.
To clean the disc
Wipe the disc with a soft cloth in a straight line from center
to edge.
DO NOT use any solvent—such as conventional
record cleaner, spray, thinner, or benzine—to clean
the disc.
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
ballpoint pen, etc.

following cases:
• After starting the heater.

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 evaporates.
• DO NOT expose discs to direct sunlight or any
heat source or place them in a place subject to
high temperature and humidity.
• DO NOT leave discs in a car.
