Maintenance

Cabinet Cleaning

Wipe the front panel and other exterior surfaces of the
unit with a soft cloth immersed in lukewarm water and
wrung dry.
Never use a solvent or alcohol. Do not spray insecticide
liquid near the unit. Such chemicals may cause damage
and discoloration to the exposed surfaces.

Panel Cleaning

Wipe the panel of the unit with a soft cloth. Before
cleaning the panel, disconnect the AC power cord.

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.
To clean-off, use a soft cloth.
Do not use a hard cloth since this will mar the disc.
Wipe the disc in a straight line form center to edge.
Never wipe with a circular motion.

Do not use detergent or abrasive cleaning agents.




Servicing

Should your unit become inoperative, do not try to correct
the problem yourself. There are no user serviceable parts
inside. Turn off the unit, unplug the AC power cord and call
our toll free customer support line found on the cover of
this manual to locate an authorized service center.

If the Laser Optical Pickup Unit is Dirty

If the unit still does not perform properly when it is
operated, while referring to the relevant sections and to
"Troubleshooting Guide" 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.

IR Signal Check

If the remote control is not working properly, you can use
an AM radio or digital camera (including a cellular phone
with built-in camera) to see if it is sending out an infrared
signal.

With an AM radio:
Tune the AM radio station to a non-
broadcasting frequency. Point the
remote control towards it, press any
button and listen. If the sound from
the radio flutters, it is receiving the
remote control’s infrared signal.

With a digital camera
(including built-in cell phone cameras):
Point a digital camera towards the remote
control. Press any button on the remote
control and look through the digital
camera. If the infrared light appears
through the camera, the remote control is
working.
