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.

<When cleaning oily surface>
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.
