Introduction

Precautions

Notes on handling
When shipping the DVD video player, the original
shipping carton and packing materials come in handy.
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 video player. Do not leave rubber or plastic
products to contact the DVD video player for prolonged
period. They will leave marks on the finish.
The top and rear panels of the DVD video player may
become warm after a long period of use. This is not a
malfunction.
When the DVD video player is not in use, be sure to
remove the disc and turn off the power.
If you do not use the DVD video player for a long
period, the unit may not function properly in the
future. Turn on and use the DVD video player
occasionally.
Notes on locating
Place the DVD video player on a level surface. Do not
use it on a shaky or unstable surface such as a
wobbling table or inclined stand. The loaded disc may
become dis-aligned and damage the DVD video
player.
When you place this DVD video player near a TV,
radio, or VCR, the playback picture may become poor
and the sound may be distorted. In this case, place
the DVD video 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
video player.
If you use a chemical saturated cloth to clean the unit,
follow that product's instructions.
To obtain a clear picture
The DVD video 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 will
deteriorate. 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.

Moisture condensation damages the DVD video
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 video player.

may damage discs and internal parts. Remove the
disc, connect the power cord of the DVD video player
to the wall outlet, turn on the DVD video player, and
leave it for two or three hours. After two or three
hours, the DVD video player will have warmed up and
evaporated any moisture. Keep the DVD video player
connected to the wall outlet and moisture
condensation will seldom occur.
