CLEANING THE DISC LENS
¡ If the DVD/VCR 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.
AUTO HEAD CLEANING
• Automatically cleans video heads as you insert or remove a cas-
sette, 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 long periods 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 your DVD/VCR 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 at 1-800-448-2244 to locate an Authorized Service
Center.
NOTES:
• Remember to read the instructions included with the video head
cleaner before use.
• Clean video heads only when problems occur.
¡ 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 from center to edge.
¡ Never wipe with a circular motion.
¡
Do not use detergent or abrasive cleaning agents.
