Operating precautions
• The signal recorded on a compact 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 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.
