Playback side
Cleaning Discs
• Fingerprints and dust on the disc cause picture and sound deterioration. Wipe the disc
from the centre outwards with a soft cloth. Always keep the disc clean.
• If you cannot wipe off the dust with a soft cloth, wipe the disc lightly with a slightly
moistened soft cloth and finish with a dry cloth.
• Do not use any type of solvent such as thinner, benzine, commercially available
cleaners or antistatic spray. They may damage the disc.
Storing Discs
• Do not store discs in places subjected to direct sunlight or near heat sources.
• Do not store discs in places subjected to moisture and dust such as a bathroom or near
a humidifier.
• Storing discs vertically in a case, stacking discs or placing objects on discs outside of
their cases may cause warping.
