8 SAFETY GUIDELINES
Correct Handling
Do not drop the disc while handling. Hold the disc so
you will not leave fingerprints on the surface. Do not
affix tape, paper, or gummed labels to the disc. Do not
write on the disc.
Disc Cleaning
Fingerprints, dust, or soil on the surface of the disc could
cause the CD player to skip. For routine cleaning, wipe
the playing surface with a clean, soft cloth from the center
of the disc to the outer edge. If the surface is heavily
soiled, dampen a clean, soft cloth in a solution of mild
neutral detergent before cleaning the disc.
