Disc Care and Maintenance
Optical discs (DVDs, CDs) contain high-density compressed data and need proper handling.
Handling a Disc
Hold a DVD/CD by its edges. Avoid touching the recorded side of the disc. To remove a DVD/CD
from its storage case, press down on the center retention mechanism of the case and lift the disc
out.
Do not subject discs to prolonged exposure to direct sunlight, high humidity, or high tempera-
tures.
Do not bend or press discs.
To reduce the risk of scratches, always put discs back in their case after use. Store discs
vertically in a cabinet.
Do not place stickers or labels on either side of a disc.
Cleaning a Disc
Use a dry, soft cloth to wipe off any fingerprints and dusts from the playing surface of the disc.
Wipe in a straight line radially from the center to the outside edge of the disc. Small dust particles
and light stains will not affect playback quality.
Never use chemicals such as record sprays, anti-static sprays, benzene, or thinners to clean
a disc. Doing so will damage the surface of the disc permanently.
