Care and Maintenance
Cleaning the DVD/VCR
• Wipe the front panel and other exterior surfaces of the DVD/VCR with a soft,
slightly damp cloth.
• Never use a solvent, thinner, benzene, or alcohol to clean the DVDNCR. Do not
spray insecticide liquid near the DVD/VCR. Such chemicals may discolor the surface
or damage the DVD/VCR.
Cleaning a Disc
• Use a soft, dry cloth to wipe the Disc.
• Wipe the Disc in a straight line from the center to the edge. Never wipe the Disc
in a circular motion.
• Do not use detergent or abrasive cleaning agents.
• Handle the Discs so fingerprints and dust do not adhere to the Discs.
• Always store the Disc in its protective case when it is not in use.
Checking the Laser
• If the DVD/VCR does not operate as described in this manual, the DVD Player's
laser may be dirty. Consult an Authorized Service Center for inspection and clean-
ing of the laser.
Caring for Video Cassettes
• Use only cassettes with the [_ mark.
• Remove any light adhesive stick-on notes from the video cassette before putting the
cassette in the VCR. Removable labels can jam the VCR.
Caring for the VCR's Video Heads
• Periodic maintenance is required to maintain your DVDNCR's excellent perfor-
mance. The VCR has an Automatic Head Cleaner. However, the video heads will
require replacement eventually. Only an authorized service center should perform
this service.
