• Do not leave things near the computer that are sensitive
to heat. During operation, the computer may become
warm.
Handling
Do not drop or hit your computer against solid objects.
Do not stand the computer on its side 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.
It is a good idea to make backup copies on floppy disks and
carry them with you.
Do not leave a floppy disk in the drive while transporting your
computer.
Do not carry your computer when it is ON.
Remove all cables before transporting your computer.
Wc recommend preparing a fully charged battery (and op­
tional charger, if possible).
When transporting spare batteries inside a package, brief­
case, etc., it is recommended that the batteries be stored
in a plastic bag.
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
with luggage. For use of the computer inside an aircraft,
we recommend asking the airlines regarding their policy
on this issue.
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 it.
Display:
Use a soft dry cloth like gauze
to lightly wipe the display.
Do not use benzene or thinner, or disinfectant-type alcohol.
Do not directly use water, liquid detergents or spray-type
cleaners. If liquid enters the computer, this may cause the
computer to malfunction or become defective.
CD-ROM
Do not allow CDs to become dirty or scratched.
Do not place or store CD in locations exposed to heat, direct
sunlight, humidity or dust.
Do not write on the surface of the CD with a ball-point pen or
other writing instrument, or apply label on the CD.
Do not drop, bend, or place heavy objects on top of CDs.
If the CD is brought from a cold into a warm environment,
moisture may form on the disc. Wipe this moisture off with a
soft, dry, lint-free cloth before using the CD.
Cleaning the CD using a CD disc cleaner is recommended
once every 2 or 3 months.
After wiping the CD with a moist, soft cloth, wipe it
with a dry cloth. Always wipe from the center toward
the edge.
