In use:
Temperature: 5 °C to 35 °C {41 °F to 95 °F}
Humidity:
30 % to 80 % RH (No condensation)
Not in use: Temperature: -20 °C to 60 °C {-4 °F to 140 °F}

Usage Environment
Such areas may result in damage to the computer.
Areas with electronic equipment
These areas may interfere with your display or cause
your computer to produce strange sounds.
Areas with extremely high/low temperatures
Places not to use your computer
Do not leave things near the computer that are sensitive to heat. During operation, the
computer may become warm.
Maintenance
Handling
Do not use benzene or thinner, or rubbing alcohol.
Doing so may be adversely affect the surface, e.g.,
discoloration. In addition, do not use commercially-
available cleaners and cosmetics, as they may con-
tain components harmful to the surface.
Do not directly add or spray water or detergent. If
liquid enters the computer, this may cause the com-
puter to work improperly or be damaged.
Areas excluding the
display
Firmly squeeze a soft wet
cloth containing water or
detergent (for kitchen use)
diluted with water and gen-
tly wipe the computer. If a
detergent other than a de-
tergent for kitchen use is
used (e.g., low-alkaline de-
tergent), it may adversely
affect the surface (e.g., dis-
coloration).
Display
Use a soft dry cloth like gauze to lightly wipe the display.
This computer has been designed so as to minimize shock to the LCD and hard disk drive,
the leakage of liquid (e.g., water) from the keyboard, etc., but no warranty is provided against
such trouble. Therefore, as a precision instrument, please be extremely careful in the han-
dling.
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. Having the optional port replicator is
very convenient.
We recommend preparing a fully charged battery (and optional 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 place the computer upright. 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
computer inside an aircraft, we recommend asking the airlines regarding their policy on this
issue.
