Handling discs

This unit has been designed to reproduce CDs, CD-Rs (Recordable), CD-RWs (Rewritable), and CD Texts.

•This unit is also compatible with MP3 and WMA discs.

How to handle discs
When removing a disc	Center holder
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 be played correctly. If a disc does become dirty, wipe it with a soft cloth in a straight line from center to edge.

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.

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.

When playing a CD-R or CD-RW

Before playing back CD-Rs or CD-RWs, read their instructions or cautions carefully.

•Use only “finalized” CD-Rs or CD-RWs.

•Some CD-Rs or CD-RWs may not be played back on this unit because of their disc characteristics, and for the following reasons:

–Discs are dirty or scratched.

–Moisture condensation on the lens inside the unit.

–The pickup lens inside the unit is dirty.

•CD-RWs may require a longer readout time since the reflectance of CD-RWs is lower than that of regular CDs.

•CD-Rs or CD-RWs are susceptible to high temperatures or high humidity, so do not leave them inside your car.

•Do not use following CD-Rs or CD-RWs:

–Discs with stickers, labels, or protective seal stuck to the surface.

–Discs on which labels can be directly printed

by an ink jet printer.

Using these discs under high temperatures or high humidity may cause malfunctions or damage to discs. For example,

–Stickers or labels may shrink and warp a disc.

–Stickers or labels may peel off so discs cannot be ejected.

–Print on discs may get sticky.

Read instructions or cautions about labels and printable discs carefully.

CAUTIONS:

•Do not insert 8 cm discs (single CDs) into the loading slot. (Such discs cannot be ejected.)

•Do not insert any disc of unusual shape—like a heart or flower; otherwise, it will cause a malfunction.

•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 them in a car.

•Do not use any solvent (for example, conventional record cleaner, spray, thinner, benzine, etc.) to clean discs.
