Occasional care and maintenance of the unit and the software
are needed to optimize the performance of your unit.

dirty, use a soft cloth lightly moistened with mild detergent
solution. Do not use strong solvents such as alcohol, benzine
or thinner.

Erroneous display.

and cords.

The disc plays poorly (DVDs).
•Check that the disc's rating level does not exceed your
setting.
•Check that the disc is a NTSC color system disc.
• Check that the unit is not connected to a video deck, through
a selector switch, or to a TV set with a built-in video deck.
Picture noise may appear due to the DVD copy protection
scheme. Turn off the power or disconnect these equipment.
•The picture quality may be poorer compared to normal
playback during pause, frame advance, fast forward or fast
reverse.
•Many DVD features, such as menu, subtitles, multi-audio,
multi-angle, and rating are dependent on the DVD software
itself. Check the instructions of your disc.

the full surround effect, check the type of your source (page

mode (page 23 and 24).
