Usage Environment
Such areas may result in damage to the computer.

Places not to use your computer
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 drop or hit your computer against solid objects.
Do not carry your computer when it is on.
Remove all cables before transporting your computer.
We recommend preparing a fully charged battery.
When transporting spare batteries inside a package, briefcase, etc., it is recommended that
the batteries be stored in a plastic bag.
Do not place the computer upright or allow it to tip over. When the computer receives
extremely strong shock after falling, the hard disk or floppy disk drive, etc., may become
inoperable.
Do not carry the computer while the display is open, or carry it by gripping the display.
Do not put anything (e.g., a piece of paper) between the display and keyboard.
Always carry your computer with you. Never check it in with luggage. For use of the
computer 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.
Do not leave a disk in the drive while transporting your computer.
Maintenance
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.
Display
Avoid using water when cleaning the panel. Ingredients included in water may leave residue
and reduce readability of the screen.
<When cleaning dust/dirt>
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 “dry” soft cloth used for cleaning glasses.
<When cleaning oily surface>
Apply camera lens cleaner on a soft gauze and clean it with gentle force. Then, wipe with
dry soft cloth used for cleaning glasses.

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 compo-
nents 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.
