5.1
Cleaning Regular cleaning will extend the life and performance of the Crystal Series LCD. Before
cleaning, be sure to unplug the power cord from the power outlet.
Cleaning the Display
Panel Body and Remote
Control Do not under any circumstances use solvents such as benzene or thinner to clean the
Crystal Series LCD. Doing so may cause deterioration or peeling of paint from the display
or remote control unit.
Wipe the display and remote control gently with a soft cloth. In case of excessive dirt
buildup, dampen a soft cloth with a diluted neutral cleaning detergent. Wring the cloth
thoroughly, then wipe the component and dry it with a dry soft cloth.
Cleaning the Screen After dusting, wipe the screen gently using a soft cloth (cotton, flannel etc.). Do not use
tissue or coarse fabric. The screen surface is easily scratched; do not rub it or hit it with a
hard object.
If you clean the surface of the screen with a wet cloth, do not allow water droplets on the
surface to enter into the product; this may cause a malfunction.
Cleaning the Vents As a general rule, use a vacuum cleaner about once a month to clean the vents on the
rear panel of the display of dust buildup (set the vacuum cleaner to its weakest setting
when doing this). If not removed, accumulated dust can cause the internal temperature to
increase, resulting in possible breakdown or fire.
