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.

in a mixture of water and detergent and squeeze it dry before
wiping off the stains. Use a soft, dry cloth for final cleaning.

increase the internal temperature of the main unit causing machine
failure or fire hazard.

temperature. This sound does not indicate that the display has a problem.
• The display has fans to maintain the temperature of internal components at a constant
level. This sound is produced by the fan as it rotates.

high-voltage transmission lines, neon signs or other potential sources of interference.
