How to operate the CD (MP3/WMA) player
About compact discs
• The information 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:
About brand new CDs
• 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 the disc. Do not 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 damage to the main unit.
• Avoid touching the recorded surface when handling a disc; handle
discs by their edges.
• You may notice that some brand new discs are rough around the
center hole or outside edge. Remove the rough edges with the side of
a ballpoint pen, etc. Rough edges may prevent proper loading in the
main unit. Flakes from the rough edges may also stick to the recorded
surface and interfere with playback.
