3.5 Cleaning and Maintenance
Note
Before cleaning the LCD display, be sure to unplug the power cord. Do not attempt to maintain it
yourself. Opening the casing will expose you to high voltage or other hazardous materials. The LCD
display must be maintained by professionals.
Clean the screen panel of the LCD display
● When wiping the screen, use a dry cloth that does not shrink, so as not to damage the surface
coating of the screen. Do not use chemical fiber cloth or detergent, whose composition may
cause the screen surface to fade or be damaged. Do not wipe the screen with a hard cloth or a
rough and hard object, as this may damage the screen surface.
● If the surface of the screen is stained with grease, such as fingerprints, wipe it with a
non-shrinking cloth diluted with neutral detergent, and then dry the screen with a soft, dry cloth.
Do not use a spray cleaner as this may remove the coating or cause the cleaner to enter the
device, which may cause malfunctions.
