Care and maintenance
Handle your discs carefully, and they will last a long time.
Compact discs
• This system can play back the following discs:
–Audio CD
–Finalized CD-R/CD-RW recorded in audio
CD format or MP3 format
However, continued use of irregular shape
discs (heart-shape, octagonal, etc.) can damage
the system.
• Remove the disc from its case by holding it at
the edges while pressing the case’s center hole
lightly.
• Do not touch the shiny surface of the disc, or
bend the disc.
• Put the disc back in its case after use to prevent
warping.
• Be careful not to scratch the surface of the disc
when placing it back in the case.
• Avoid exposure to direct sunlight, temperature
extremes, and moisture.
• A dirty disc may not play correctly. If a disc
does become dirty, wipe it with a soft cloth in a
straight line from center to edge.
CAUTION:
Do not use any solvent (for example,
conventional record cleaner, spray thinner,
benzine, etc.) to clean a disc.

discs and the mechanism clean.

shelves.
• Keep the disc compartment door closed when not in use.
Cleaning the lens

Open the disc compartment door and clean the lens as shown.

cotton swab.
