HANDLING THE DISCS
Dirt, dust, scratches and warpage cause sound skips during playback and a
deterioration of sound quality. How to take care of your disc:
1. Use compact discs that have the mark shown on the right.
2. Fingerprints and dust should be carefully wiped off the disc’s signal surface (glossy
side) with a soft cloth. Unlike conventional records, the compact disc has no
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 irreparably 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.
