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 DVD/VCR. 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 DVD/VCR’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.
