Maintenance

Servicing
• Please refer to relevant topics on "Troubleshooting" on
page 46 before returning the product.
• If this unit becomes inoperative, do not try to correct the
problem by yourself. There are no user-serviceable parts
inside. Turn the unit to the standby mode, unplug the
power plug, and please call our toll free customer
support line found on the cover of this manual to locate
an authorized service center.
Cleaning the cabinet
• Wipe the front panel and other exterior surfaces of the
unit with a soft 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 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.
• Note that discs with special shapes (heart-shaped discs,
octagonal discs, etc.) cannot be played back on this unit.
Do not attempt to playback such discs, as they may
damage the 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 to a
nonbroadcasting frequency. Point the
remote control towards it, push 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. Push 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.
