PRELIMINARY

5.1

Cleaning

Regular cleaning will extend the life and performance of the CinemaWall. 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
CinemaWall. 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 the case of excessive dirt
buildup, dampen a soft cloth with a diluted neutral cleaning detergent and after wringing
the cloth thoroughly, wipe the component and then dry it with a dry soft cloth.
Cleaning the ScreenAfter dusting, wipe the screen gently using the supplied cleaning cloth or another soft
cloth (cotton, flannel etc.). Do not use tissue or a rough cloth. 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, water droplets on the surface may
enter into the product and cause a malfunction.
Cleaning the VentsAs 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.
