●
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 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 adhere of paper or tape on, nor write on
or scratch either side of a disc.
●
Discs spin at a high speed inside the main unit.
Keep cracked or warped discs out of the player
to avoid damaging the main unit.
●
Avoid touching the recorded surface when
handling a disc; handle discs by their edges.
