Care and maintenance
Occasional care and maintenance of the unit and the software
are needed to optimize the performance of your unit.
To clean the cabinet

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

cleaning cloth. After playing a disc, store it in its case. Do not
keep it in hot or humid places.

Troubleshooting
If your unit fails to perform properly, check the following guide
and the relevant sections of the Operating Instructions.
There is no sound.
•Check speakers and AC power connection.
The unit shuts off suddenly.
Possibly a short circuit in the speaker terminals. Disconnect
the AC power cord from the AC power outlet and re-connect
the speaker cords correctly.
The unit blacks out when the unit is turned off.
•Check your ECO mode setting.
Erroneous display.
•Reset the unit.
Poor radio reception.
Check antenna connection. Adjust the antenna to find the
best reception.
Move unit and antenna away from other electric appliances
and cords.
The disc plays poorly (general).
•Check if the disc is correctly loaded.
Check if the disc is not dirty.
Check if the pickup lens is not affected by condensation. If
so, wait approximately one hour and try again.
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.
If a multichannel source does not seem to be played with
the full surround effect, check the type of your source (page
22), selected audio track (page 21), and selected listening
mode (page 23 and 24).
