shock or re. Periodically examine the cord of your
appliance, and if its appearance indicates damage
or deterioration, unplug it, discontinue use of the
appliance, and have the cord replaced with an
exact replacement part by an authorized service
center. Protect the power cord from physical or
mechanical abuse, such as being twisted, kinked,
pinched, closed in a door, or walked upon. Pay
particular attention to plugs, wall outlets, and
the point where the cord exits the appliance. The
Power Plug is the disconnecting device. In case of
an emergency, the Power Plug must remain readily
accessible.

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.
