Handling & Cleaning DISC
Handling
-Dirty, scratched or warped discs may cause skipping or noise.
-To keep the disc clean, only handle the disc by its edges.
-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 warp the
disc (such as leaving the discs in your car in summer heat).
-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 unlabelled side. Do not attach any seal, label or data protection sheet to
either side of a disc.
Cleaning DISC
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 or dirt, so gently wiping them
with a soft cloth should remove most dust or stains. Wipe in a
straight motion from the centre to the edge.
CAUTION: Never use thinner benzene, record cleaner or anti-static spray on a compact disc.
Such chemicals can damage its plastic surface.
