•FINGERPRINTS ON LENS

Use a cotton swab starting in the middle and working to the outside edge, pay attention in doing this operation or the pick up lens could be damaged.

CLEANING THE CABINET

Wipe with a soft cloth. If the cabinet is very dirty, dampen (not dripping wet) the cloth with a weak solution of soap water, and then wipe clean.

HANDLING COMPACT DISCS

1. This unit is designed to play compact discs bearing the identification logo to the right. Discs that do not carry this logo may not conform to the CD standard and may not play properly.

2.Dirty, scratched or warped discs may cause skipping or noise. Pay attention to the following: Handle the disc only by the edges. To keep the disc clean, do not touch the surface of the disc.

3.Discs should be returned to their cases after use to avoid serious scratches that could cause the laser pickup to skip.

4.Do not expose discs to direct sunlight, high humidity, or high temperatures for ex- tended periods. Prolonged exposure to high temperatures can warp the disc.

5.Do not stick or write anything on either side of the compact disc. Sharp writing instru- ments, or the inks used in some felt-tip pens, may damage the surfaces of the disc.

6.Always place the compact disc to be played in the CD compartment with the label facing upward. CD can be played on only one side.

CLEANING DISCS

1.Fingerprints should be wiped from the surface of the disc with a soft cloth. Unlike conventional records, compact discs have

no grooves to collect dust and microscopic debris, so gently wiping them with cloth should remove most of the particles. Wipe in a straight motion from the inside to the outside of the disc.

2.Never use such chemicals as record cleaning sprays, anti-static sprays, benzene or thinner to clean compact disc. Such chemi-

cals can damage the plastic of the disc.

•The unit will not play a disc that has been inserted upside down, or discs that do not conform to the Compact Disc standard. Also, the unit might not play discs that are scratched, soiled or carry fingerprints.

•Both 8cm and 12cm discs can be played in this unit.
