Precautions (cont’d)
Before you start
SERVICING
• Please refer to relevant topics on Troubleshooting on pages 78-81 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 off, unplug the power plug and please call our help line mentioned
on the front page to locate an Authorized Service Center.
CLEANING THE CABINET
• Use a soft cloth slightly moistened with a mild detergent solution. Do not use a solution containing
alcohol, spirits, ammonia or abrasive.
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 analogue 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.
AUTO HEAD CLEANING
• Automatically cleans video heads as you insert or remove a cassette, so you can see a clear picture.
• Playback picture may become blurred or interrupted while the TV program reception is clear. Dirt
accumulated on the video heads after a long period of use, or the usage of rental or worn tapes
can cause this problem. If a streaky or snowy picture appears during playback, the video heads in
the unit may need to be cleaned.
1. Please visit your local Audio/Video store and purchase a good quality VHS Video Head Cleaner.
2. If a Video Head Cleaner does not solve the problem, please call our help line mentioned on the
front page to locate an Authorized Service Center.
NOTES:
• Remember to read the instructions along with the video head cleaner before use.
• Clean video heads only when problems occur.
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 a AM radio to a band 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 unit 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 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 record-
able 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.
