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.
• If you do not use the DVD player for a long period, the unit may not function properly in the future.
Turn on and use the DVD player occasionally.
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.
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 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.
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 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 opti-cal 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. Remove the disc, 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. 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.
