CLEANING THE CABINET
¡Use a soft cloth slightly moistened with a mild detergent solution. Do not use a solution containing alcohol, spir-
its, ammonia or abrasive.
CLEANING DISCS
¡When a disc becomes dirty, clean it with a cleaning cloth. Wipe the disc from the center 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.
RECOMMENDED MEASURES FOR OPTIMUM PICTURE EXCELLENCE
This Unit is a precision device constructed using extremely accurate technology.
¡The disc cannot be played if the disc drive component is worn out or if the internal pick up lens is dirty.
¡If this unit still does not perform properly although you refer to the relevant sections and to Troubleshooting
Guide on page 29, the laser optical pickup unit may be dirty. Consult a Sharp 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 your VCR/DVD 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 page 28 to locate
a Sharp Authorized Service Center.
Maintenance
Hint Hint
• Remember to read the instructions along with the video head cleaner before use.
