Do not leave things near the computer that are sensitive to heat. During operation, the
computer may become warm.

Handling
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 in the handling.
Do not drop or hit your computer against solid objects.
Do not carry your computer when it is on.
Remove all external devices and cables, and PC Cards sticking out of the computer (see the
figure on the left) before transporting the computer.
We recommend preparing a fully charged battery.
When transporting spare batteries inside a package, briefcase, etc., it is recommended that it
be placed in a plastic bag so that its contacts are protected.
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 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.
