INTRODUCTION
Precautions
Notes on handling
When shipping the DVD player, 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 player. Do not leave rubber or
plastic products in contact with the DVD player for
a long time. They will leave marks on the finish.
The top and rear panels of the DVD player may
become warm after a long period of use. This is
normal and not a malfunction.
When the DVD player is not in use, be sure to
remove the disc and turn off the power.
Notes on Locating
When you place this DVD player near a TV, radio,
or VCR, the playback picture may become poor
and the sound may be distorted. In this case,
move the DVD player away from the TV, radio, or
VCR.
To Obtain a Clear Picture
The DVD player 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 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 benzene, as they
may damage the surface of the DVD player.
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.
Notes on Moisture Condensation
Moisture condensation damages the DVD player.
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
optical pick-up lens inside this unit, one of the
most crucial internal parts of the DVD player.
Moisture condensation occurs during the following
cases.
When you bring the DVD player directly from a
cold place to a warm place.
When you use the DVD player 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 player in a hot
and humid place just after you move the unit from
an air conditioned room.
When you use the DVD player in a humid place.
Do not use the DVD player when moisture
condensation may occur.
If you use the DVD player in such a situation, it
may damage discs and internal parts. Connect
the power cord of the DVD player to the wall
outlet, turn on the DVD player and leave it “ON”
for two or three hours. If a disc is present inside
the machine, remove it immediately. After two or
three hours, the DVD player will have warmed up
and evaporated any moisture. Keep the DVD
player connected to the wall outlet and moisture
condensation will seldom occur.
