4.Do not expose discs to direct sunlight, high humidity, or high temperatures for extended 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 instruments, 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 chemicals 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.
