Precaution
Be sure to remove the power plug from the receptacle before cleaning the display.
And 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 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 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.
Check the following explanation again before asking for services. If the trouble cannot be recovered,
consult your dealer.
