Cleaning the Cabinet
• Wipe the front panel and other exterior surfaces of the
unit with a soft, slightly damp cloth.
• Never use a solvent, thinner, benzene or alcohol to
clean the unit. Do not spray insecticide liquid near the
unit. Such chemicals may discolor the surface or
damage the unit.
Cleaning Discs
• When a disc becomes dirty, clean it with a cleaning
cloth. Wipe the disc from the center to out. Do not
wipe in a circular motion.
• Do not use solvents such as benzine, thinner,
commercially available cleaners, detergent, abrasive
cleaning agents or antistatic spray intended for analog
records.
Cleaning the Disc Lens
• If this unit still does not perform properly although you
refer to the relevant sections and to
"TROUBLESHOOTING" in this owner's manual, the laser
optical pickup unit may be dirty. Consult your dealer or
an Authorized Service Center for inspection and
cleaning of the laser optical pickup unit.
Disc Handling
• Handle the discs so that fingerprints and dust do not
adhere to the surfaces of the discs.
• Always store the disc in its protective case when it is
not used.

PRECAUTIONS
IR Signal Check
If the remote control does not work properly, you can test if
the remote control sends out the infrared signal with AM
radio or a digital camera (including built-in camera of cellular
phone). It will help to define the cause of malfunction.
• With an AM radio:
Tune an AM radio to a station with no
broadcasting. Press a button on remote
control toward the radio. Sound will be
fluttering when you press any key and the
radio receives the signal. This means the
remote control is working.
• With a digital camera (including built-in camera of
cellular phone):
Direct a digital camera to remote control,
press and hold a button on remote control. If
infrared light appears through digital camera,
the remote control is working.
Dolby Digital Recording
"Dolby® Digital Recording enables consumers to record
high-quality video with stereo sound on recordable DVD
discs. The technology, when utilized instead of PCM
recording, also saves recordable disc space, allowing for
higher video resolution or extended recording time on
each DVD. DVDs created using Dolby Digital Recording
will play back on all DVD-video players."
Note: This is true when the players are compatible with
actual recordable DVD discs.
