The compact disc digital audio system offers the best possible sound reproduction–on a small, convenient disc.
Its remarkable performance is the result of a unique combination of digital storage and laser optics.

For best results, you should apply the same care in storing and handling the compact disc as you would with conventional records. No cleaning is necessary if the compact disc is always held by its edges and is replaced in its case directly after playing. If the compact disc becomes soiled by fingerprints, dust or dirt, it can be wiped (always in a straight line, from center to edge) with a clean and lint-free, soft, dry cloth. Never use a solvent or abrasive cleaner to clean the disc.

If you follow these suggestions, the compact disc will provide a lifetime of listening enjoyment.
