Operating precautions
About CDs and DVDs
• The signal recorded on a disc is read by a laser beam, so nothing
touches the disc surface. A scratch on the recorded surface or a badly
warped disc may cause deteriorated sound quality or intermittent
playback. Observe the following precautions to ensure high quality
sound performance:

• Do not leave an ejected disc in the disc
slot for very long; the disc may warp.
Discs should be stored in their cases and
kept away from high temperature and
humidity.
• Do not stick a piece of paper or tape on,
nor write on or scratch either side of a
disc.
• Discs spin at a high speed inside the
deck. Keep cracked or warped discs out
of the player to avoid damaging it.
• Avoid touching the recorded surface when
handling a disc; handle discs by their
edges.
