Operation
Useful Information
Handling
Display (LCD)
Use the Soft Cloth included with the computer. (For more information, refer to “Suggestions
About Cleaning the LCD Surface” that comes with the Soft Cloth.)
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.
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 com-
puter, it may cause it to work improperly or be damaged.
CAUTION
Maintenance
This computer has been designed so as to minimize shock to the LCD and hard disk drive, the
leakage of liquid (e.g., water) on to the keyboard, etc., but no warranty is provided against such
trouble. Therefore, as a precision instrument, be extremely careful when handling.
When carrying the computer, be sure to keep to the following:
Turn off the computer.
Remove all external devices, cables, PC Cards protruding from the computer (see figure on
the left), and SD Memory Cards before transporting the computer.
Do not drop or hit your computer against solid objects.
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.
When taking an airplane, always carry your computer with you. Never check it in with
luggage. Before using the computer inside an airplane, we recommend asking the airlines
regarding their policy on this issue.
Do not leave a disk in the drive while transporting your computer.
When transporting a spare battery pack inside a package, briefcase, etc., it is recommended
that it be placed in a plastic bag in order to protect its contacts.
We recommend the following:
Preparing a fully charged battery pack (and optional charger, if possible).
Making backup copies on discs and carrying them with you.

periods of time in an environment with exceptionally low or high temperatures or high humid-
ity may result in deterioration of the product, which can lead to a reduction in product life.
