■Handling compact discs

•Always handle a disc with care so that its surface is not scratched.

•Compact discs are rarely worn out during playback, but damage to the disc surface when the disc is being handled can adversely affect the disc playback.

•Be sure to use a felt-tip pen or similar writing tool when writing on the label side of a disc. Do not use a ball-point pen, pencil, or other hard-tipped writing tools as these may damage the disc and may adversely affect the disc playback.

•Do not warp discs.

•When a disc is not currently being used, remove it from this unit and store it in an appropriate case.

•When removing or storing a disc, be careful not to scratch the playing surface.

•Compact discs are not affected by small particles of dust or fingerprints on their playing surface, but even so they must be kept clean. Wipe the disc surface with a clean, cry cloth. Do not wipe the disc surface with a circular motion; wipe it straight outward from the center.

•Do not try to clean the disc surface with any type of disc cleaner, record spray, anti-static spray or liquid, or any other chemical-based liquid as such substances may irreparably damage the disc surface.

•Do not expose discs to direct sunlight, high temperature, or high humidity for a long period of time as these conditions may warp or otherwise damage the disc.

•To play back an 8-cm (3-inch) compact disc, place it in the inner recessed area of the disc tray. Do not put a normal 12-cm CD on top of an 8-cm CD.
