CLEANING AND MAINTENANCE
Precautions
Be sure to remove the power plug from the receptacle before cleaning the display.
Be sure not to clean the display using a cloth dampened with volatile solvents, such as benzene or thinner.  Such solvents can harm the 
display’s cabinet, the filter at the screen front, and the remote control.  They can also cause paint to come off these sections.
Cleaning the Screen
Clean the screen gently with a soft cloth.
The screen surface is fragile.  Never attempt to clean it with a hard material, press on it forcefully, or tap it.
Cleaning the Cabinet and Remote Control
Use a soft cloth for cleaning.
If the cabinet or remote control is heavily stained, soak a soft cloth in a mixture of water  and detergent and squeeze it dry before wiping off the 
stains.  Use a soft, dry cloth for final cleaning.
Cleaning the ventilation grille
Remove dust from the ventilation grille in the rear of the main unit periodically with a vacuum cleaner as the accumulated dust can increase 
the internal temperature of the main unit causing machine failure or fire hazard.
In the event of problems with the display, check the following explanations before contacting your dealer for servicing.
