Servicing
Should your DVD player become inoperable, do not try to correct the problem by yourself. There
are no user-serviceable parts inside. Turn the power off, unplug the power cord, and please call our
help line at 1-800-332-2119 to locate an Authorized Service Center.
Cabinet Cleaning
• Wipe the front panel and other exterior surfaces of the DVD player with a soft cloth immersed in
lukewarm water and wrung dry.
• Never use a solvent or alcohol. Do not spray any type of liquid near the DVD player. Certain
chemicals may cause damage and discoloration to the exposed surfaces.
If the Laser Optical Pickup Unit is Dirty
• If the player still does not perform properly when it is operated and you have referred to the
NEVER ATTEMPT TO PLAYBACK A DISC THAT IS CRACKED OR BROKEN !
relevant sections and to the “Troubleshooting Guide” for help, 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.
Adhesive labels
• Discs that are irregularly shaped, contain a scratch protection film or have an adhesive paper label
or sticker should not be inserted into this player.
Over time, the label or sticker may cause the disc to be stuck in the player, possibly causing damage
to your player.
If you wish to play "homemade" discs in this player, it is recommended you use a permanent felt tip
marker to identify the disc.
