Handling discs
Dirty, scratched or warped discs may cause skip ping or noise.
Handle the disc only by the edges. To keep clean do not touch its surface.
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
summertime).
Do not stick or write anything on either side of disc. Sharp writing instruments, or the inks 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
1. Cleaning the cabinet
Wipe with a soft cloth. If the cabinet is very dampen (not dropping wet) the cloth with a weak solution of soapy
water, and then wipe clean.
2. 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 must panicles. Wipe in a straight motion from the center to the edge.
Never use thinner benzine, record cleaner or anti static spray on a compact
disc. Such chemicals can damage its plastic surface.
