Maintenance

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 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
A), SD memory cards, and MultiMedia Cards before transporting the computer.
Close the display, and ensure that the latch is positioned correctly in the slot.
Do not carry the computer by gripping the display or the cabinet around the display (see figure B).
Lay the carrying cloth that comes with the computer across the keyboard (see figure C), and
close the display gently. When closing the display, take care to ensure that the carrying cloth
does not get caught in the panel switch, and check that the latch on the computer body (
page 12) is properly aligned.
Do not drop or hit the computer against solid objects.
If the computer is being carried in a soft bag when the battery pack has been removed, be careful
to avoid undue pressure on the body of the computer in a crowded place, etc., as this may result
in damage to the LCD.
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.
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.
