deterioration of sound qualit
y. How to take care of your disc:
1. Use compact discs that have the mark shown on the right.

grooves to collect dust and microscopic debris, so gently wipe with a soft cloth
should
remove most particles. Wipe in a straight motion from the inside to the
outside
of the disc. Small dust particles or light stains will have absolutely no effect
on
reproduction quality.
3. Never use such chemicals as record sprays, antistatic sprays or fluid, benzene or
thinner to clean compact discs. Such chemicals would ir
reparably damage the
disc’s plastic surface.
4. Discs should be put back in their cases after to avoid serious scratches that could
cause sound skip.
5. Do not expose discs to direct sunlight, high humidity, or high temperatures for
extended
periods of time. Long exposure to high temperatures can warp the disc.
6. Do not stick paper or write anything with a ball point pen on the disc surface.
