Maintenance
To clean the LCD panel
<Only for model without touchscreen>
Do not use water to clean the panel. Ingredients included in water may leave scratches and reduce readability of the
screen.
To remove dust or dirt, do not use a cloth to rub it off since it may leave scratch on the screen.
Use a fine brush to sweep dust or dirt, then wipe with a dry soft glass-cleaning cloth.
To clean the oily surface, use a soft gauze dipped in camera lens cleaner, and then wipe with a dry soft glass-clean-
ing cloth.
<Only for model with touchscreen>
Use the soft cloth included with the computer. (For further information, refer to "Suggestions About Cleaning the LCD
Surface" that comes with the soft cloth.)
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.
