Precautions
Handling the unit
When shipping the unit
Retain your original shipping carton and packing materi-
als. For maximum protection, re-pack the unit as it was
originally packaged at the factory.
When setting up the unit
The picture or sound of nearby electrical equipment
may cause distortion during playback. When this
occurs, position the unit away from the interfering
devices, or turn off the unit after removing the disc.
To keep the surface clean
Do not use volatile liquids, such as insecticide spray,
near the unit. Do not leave rubber or plastic products in
contact with the unit for a long period of time. They may
leave marks on the surface.
Cleaning the unit
To clean the cabinet
Use a soft, dry cloth. If the surfaces are extremely dirty,
use a soft cloth lightly moistened with a mild detergent
solution. Do not use strong solvents such as alcohol,
benzine, or thinner, as these might damage the surface
of the unit.
To obtain a clear picture
The DVD+VCR is a high-tech, precision device. If the
optical pick-up lens and disc drive parts are dirty or
worn, the picture quality will be poor.
Regular inspection and maintenance are recommended
after every 1,000 hours of use. (This depends on the
operating environment.)
For details, please contact your nearest dealer.
Notes on Discs
Handling discs
Do not touch the playback side of the disc.
Hold the disc by the edges so that fingerprints will not
get on the surface.
Do not stick paper or tape on the disc.
Storing discs
After playing, store the disc in its case.
Do not expose the disc to direct sunlight or sources of
heat, or leave it in a parked car exposed to direct sun-
light.
Cleaning discs
Fingerprints and dust on the disc can cause poor pic-
ture quality and sound distortion. Before playing, clean
the disc with a clean cloth. Wipe the disc from the cen-
ter out.
Do not use strong solvents such as alcohol, benzine,
thinner, commercially available cleaners, or anti-static
spray intended for older vinyl records.
Cleaning the Video Heads
Playing poor quality or damaged tapes can contaminate
the video heads. Use only high quality tapes in your
DVD+VCR. Dirt which accumulates on the video heads
may cause the picture to blur. If this happens, the video
heads need to be cleaned. Purchase a non-abrasive
head cleaning tape from your video dealer.
