Handling discs
-
Dirty, scratched or warped discs may cause skip ping or noise.
-
Handle the disc only by the edges. Do not touch its surface to keep it clean.
-
Discs should be stored in their cases after use to avoid scratches.
-
Do not expose discs to direct sunlight, high humidity, high temperature or dust.
-
Prolonged exposure to extreme temperature can wrap the disc (such as leaving the discs in your car
during summer time).
-
Do not stick or write anything on either side of disc. Sharp writing instruments, or the ink used in
some felt-tip pens, may damage its surface.
-
Do not touch the unlabeled side. Do not attach any seal, label or data protection sheet to either side
of a disc.
Cleaning discs
Fingerprints should be carefully wiped from the surface of disc with a soft cloth. Unlike conventional
records, compact discs have no grooves to collect dust and macroscopic dirt, so gently wiping them with
a soft cloth should remove most dust or stains. Wipe in a straight motion from the center to the edge.
Caution: Never use a thinner benzine, record cleaner or anti static spray on a compact disc. Such
chemicals can damage its plastic surface.
