Handling

This computer has been designed so as to minimize shock to the LCD and hard disk drive, etc.,

but no warranty is provided against such trouble. Therefore, as a precision instrument, be

extremely careful in the handling.

Do not carry the computer while the display is open, or carry it by gripping the display or the

cabinet around the display (see figure A). When closing the display, ensure that the latch is

positioned correctly in the slot .

Do not carry your computer when the power is on.

Do not drop or hit your computer against solid objects.

Remove all external devices, cables, PC Cards sticking out of the computer (see figure B),

SD memory cards, and MultiMedia Cards before transporting the computer.

We recommend preparing a fully charged battery pack.

When transporting a spare battery pack inside a package, briefcase, etc., it is recommended

that it be placed in a plastic bag so that its contacts are protected.

Always carry your computer with you. Never check it in with luggage. For use of the com-

puter inside an aircraft, we recommend asking the airlines regarding their policy on this issue.

It is a good idea to make backup copies on disks and carry them with you.

Touch Pad

Display

Avoid using water when cleaning the panel. Ingredients included in water may leave scratches

and reduce readability of the screen.

Avoid rubbing off dust/dirt with cloth since it may leave scratch on the screen.

Sweep dust/dirt with fine brush, then wipe it with a dry soft cloth used for cleaning glasses.

Apply camera lens cleaner on a soft gauze and clean it with gentle force. Then, wipe with a

dry soft cloth used for cleaning glasses.

Areas excluding the display

Wipe these areas with a soft cloth, after applying water or detergent diluted with water to the

soft cloth and firmly wringing out excess water.

Maintenance

Do not use benzene, thinner, or rubbing alcohol. Doing so may adversely affect the

surface, e.g., discoloration. In addition, do not use commercially-available household

cleaners and cosmetics, as they may contain components harmful to the surface.

Do not directly add or spray water or detergent. If liquid enters the inside of the

computer, it may cause it to work improperly or be damaged.
