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.
