Maintenance
Notes on Discs
Handling Discs
Never 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
and never leave it in a parked car exposed to direct
sunlight.
Cleaning Discs
Fingerprints and dust on the disc can cause poor
picture quality and sound distortion. Before playing,
clean the disc with a clean cloth. Wipe the disc from
the center to out.
Do not use strong solvents such as alcohol,
benzine, thinner, commercially available cleaners,
or anti-static spray intended for old vinyl records.
Handling the Unit
When shipping the unit
Please save the original shipping carton and
packing materials. If you need to ship the unit, for
maximum protection, re-pack the unit as it was
originally packed at the factory.
Keeping the exterior surfaces clean
Do not use volatile liquids such as insecticide spray
near the unit. Wiping with strong pressure may
damage the surface. Do not leave rubber or plastic
products in contact with the unit for a long period
of time.
Cleaning the unit
To clean the player, 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.
Maintaining the Unit
The unit is a high-tech, precision device. If the
optical pick-up lens and disc drive parts are dirty
or worn, the picture quality could be diminished.
For details, please contact your nearest authorized
service center.
