Suggestions About Cleaning the LCD Surface
To improve the outdoor visibility of the display, a low refl ection coating has been added. In order to avoid scratches
and peeling of this coating, an approved soft cloth has been included to wipe the LCD surface of the computer.
Before using the computer, be sure to read the instructions provided below.
• Be sure to wipe the LCD display to remove fi ngerprints, etc., with the soft cloth.
• Do not wipe areas other than the LCD display with the soft cloth.
<How to use the soft cloth>
• Use the soft cloth when it is dry. Do not apply water or solvents to the soft cloth.
• First, lightly wipe foreign particles and dust adhering to the LCD display on one side of the soft cloth. Do not use
force, since the LCD surface may be damaged with the foreign particles or dust.
Next, wipe off fi ngerprint, etc., with the other side of the soft cloth.
After wiping off foreign particles and dust, wash the soft cloth (refer to the following) to remove the foreign par-
ticles and dust from the soft cloth.
• When the soft cloth becomes dirty, wash it with neutral detergent. Do not use bleach or a fabric conditioner (soft-
ener), or carry out sterilization by boiling.
• If the LCD gets wet, wipe the surface lightly with the soft cloth.
• While wiping the LCD display, the computer must be turned off.
<Only for model without touchscreen>
Wipe with a soft dry cloth such as gauze.
To clean areas other than the LCD panel
Wipe with a soft dry cloth such as gauze. When using detergent, dip a soft cloth in water-diluted detergent and wring it
thoroughly.
CAUTION
Do not use benzene, thinner, or rubbing alcohol since it may adversely affect the surface causing discoloration, etc.
Do not use commercially-available household cleaners and cosmetics, as they may contain components harmful to
the surface.
Do not apply water or detergent directly to the computer, since liquid may enter inside of the computer and cause
malfunction or damage.
