Precautions

Notes on handling
When shipping the DVD receiver, always use the
original shipping carton and packing materials.
For maximum protection, repack the unit as it was
originally packed at the factory.
Do not use volatile liquids, such as insect spray, near
the DVD receiver. Do not leave rubber or plastic
products in contact with the DVD receiver for a long
time. They will leave marks on the finish.
The top and rear panels of the DVD receiver may
become warm after a long period of use. This is
normal and not a malfunction.
When the DVD receiver is not in use, be sure to
remove the disc and turn off the power.
If you do not use the DVD receiver for a long period,
the unit may not function properly in the future. Turn
on and use the DVD receiver occasionally.
Notes on Locating
When you place this DVD receiver near a TV, radio, or
VCR, the playback picture may become poor and the
sound may be distorted. In this case, move the DVD
receiver away from the TV, radio, or VCR.
Notes on Cleaning
Use a soft, dry cloth for cleaning.
For stubborn dirt, soak the cloth in a weak detergent
solution, wring well and wipe. Use a dry cloth to wipe
it dry. Do not use any type of solvent, such as thinner
and benzine, as they may damage the surface of the
DVD receiver.
If you use a chemical saturated cloth to clean the
unit, follow that product's instructions.
Warning: Cleaning and adjustment of lenses
and/or other components of playback mechanism
should be performed by a qualified service
technician.
To Obtain a Clear Picture
The DVD receiver is a high technology, precision device.
If the optical pick-up lens and disc drive parts are dirty or
worn down, the picture quality becomes poor. To obtain
a clear picture, we recommend regular inspection and
maintenance (cleaning or parts replacement) every
1,000 hours of use depending on the operating
environment. For details, contact your nearest dealer.
Notes on Moisture Condensation
Moisture condensation damages the DVD receiver.
Please read the following carefully.
Moisture condensation occurs, for example, when
you pour a cold drink into a glass on a warm day.
Drops of water form on the outside of the glass. In
the same way, moisture may condense on the opti-
cal pick-up lens inside this unit, one of the most cru-
cial internal parts of the DVD receiver.
Moisture condensation occurs during the following
cases.
When you bring the DVD receiver directly from a
cold place to a warm place.
When you use the DVD receiver in a room where you
just turned on the heater, or a place where the cold
wind from the air conditioner directly hits the unit.
In summer, when you use the DVD receiver in a hot
and humid place just after you move the unit from
an air conditioned room.
When you use the DVD receiver in a humid place.
Do not use the DVD receiver when moisture
condensation may occur.
If you use the DVD receiver in such a situation, it
may damage discs and internal parts. Remove the
disc, connect the power cord of the DVD receiver to
the wall outlet, turn on the DVD receiver and leave
it "ON" for two or three hours. After two or three
hours, the DVD receiver will have warmed up and
evaporated any moisture. Keep the DVD receiver
connected to the wall outlet and moisture conden-
sation will seldom occur.
