Handling Discs
• Never touch the underside of a disc. Always hold discs
by the edge, as shown.
• Never attach adhesive tape or sticky labels to discs.
Cleaning Discs
• For best results, keep your discs clean. Fingerprints
and dust can affect the sound quality and should be
removed as follows. Using a clean, soft cloth, wipe
from the center outwards, as shown. Never wipe in a
circular direction.
✔
• To remove stubborn dust or dirt, wipe the disc with a
damp, soft cloth, and then dry it with a dry cloth.
• Never use solvent-based cleaning fluids, such as thin-
ner or benzine, commercially available cleaners, or
antistatic sprays intended for vinyl records, as they
may damage the disc.
Storing Discs
• Don't store discs in places subject to direct sunlight or
near heat sources.
• Don't store discs in places subject to moisture or dust,
such as in a bathroom or near a humidifier.
• Always store discs in their cases and vertically. Stack-
ing, or putting objects on unprotected discs may cause
warping, scratches, or other damage.
