CABINET CLEANING

Never use a solvent or alcohol. Do not spray insec- ticide liquid near the unit. Such chemicals may cause damage and discoloration to the exposed sur- faces.

SERVICING

Should your unit become inoperative, do not try to correct the problem by yourself. There are no user- serviceable parts inside. Turn off, unplug the power cord and please call our help line at 1-800-242- 7158, to locate an Authorized Service Center.

IF THE LASER OPTICAL PICKUP UNIT IS DIRTY

If the unit still does not perform properly when it is operated, while referring to the relevant sections and to "TROUBLESHOOTING GUIDE" in this Owner's Manual, the laser optical pickup unit may be dirty. Consult your dealer or an Authorized Service Center for inspection and cleaning of the laser optical pickup unit.

DISC HANDLING

Use discs which have the following logos on them. (Optical audio digital discs.)

Recordable ReWritable

Handle the discs so that fingerprints and dust do not adhere to the surfaces of the discs.

To clean-off, use a soft cloth.

Do not use a hard cloth since this will mar the disc. Wipe the disc in a straight line from center to edge. Never wipe with a circular motion.

Do not use detergent or abrasive cleaning agents.

Always store the disc in its protective case when it is not used.
