Places not to use your computer
• Such areas may result in damage to the computer.
Areas exposed to direct sunlight
Areas with electronic equipment
These areas may interfere with your
display or cause your computer to
produce strange sounds.
Q
Areas with extremely high/low temperatures
• Do not leave things near the computer that are sensitive
to heat. During operation, the computer can become
quite hot.
Carrying
• 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.
• We recommend preparing a fully charged battery (and op¬
tional charger, if possible).
When transporting spare batteries inside a package, briefcase,
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.
• Do not drop or hit your computer against solid objects.
• If you have to ship your computer, make absolutely sure
that it is packed with adequate protection.
When flying
Always carry your computer with you. Never check it with
luggage.
Maintenance
Do not use solutions such as benzene or
thinner. A soft, dry cloth is recommended.
When oil accumulates on the sur¬
face of the touch pad, use a damp
cloth with dish washing liquid to
wipe the surface, or a compact
cassette head cleaner to remove
the oil. The cursor may not move
well when the surface is not
clean.
Do not use a dry/wet (with water) cloth
to wipe the display. We recommend
cleaning the display with a soft cloth
applied with isopropyl alcohol or ethyl
alcohol. Please do not use other types
of chemicals.
Cleaning the DVD drive
using a disc lens cleaner
(excluding liquid type
cleaner) is recommended.
CD-ROM
• Do not allow discs to become dirty or scratched.
• Do not place or store discs in locations exposed to heat, direct
sunlight, humidity or dust.
• Do not write on the surface of the disc with bail-point pen or
other writing instrument.
• Do not drop, bend, or place heavy objects on top of discs.
• If the disc is brought from 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 disc.
• Cleaning the disc using a disc cleaner (LF-K022DC) is
recommended once every 2 or 3 months.
If a disc gets dirty, after wiping the disc with
a moist, soft cloth, wipe it with a dry cloth.
Always wipe from the center toward the edge.
