HANDY TIPS
In the event of problems with the display, check the following explanations before contacting your dealer for servicing.
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.
