5
Precautions
Cables
Use of an interface cable longer than 3m (118.11 inches)
is not recommended.
Against Computer Viruses
Anti-virus software is not supplied. However, you should
obtain such software if you plan to transfer files actively or
to use the Internet.
Handling the AC Adapter
Handling
Avoid Magnetic Fields
Keep the computer away from magnets.
Avoid Stacking
Do not place heavy objects on top of the
computer.
Keep Small Objects Away
Do not insert paper clips or other small objects
into the computer.
Do Not Disassemble the Computer
Do not attempt to disassemble your computer.
Prevent Shock
Avoid subjecting the computer to severe
vibrations or impact. Do not place the computer
inside a car trunk.
Avoid Radio Frequency Interference
Do not place the computer near a television or
radio receiver.
Avoid Humidity Liquids and Dust
Do not store or use the computer in locations
exposed to high humidity, liquids (including
rain) or dust.
Avoid Direct Sunlight on the LCD Panel
The LCD panel should not be exposed to direct
sunlight or ultraviolet light.
Do not twist or pull the AC power cord forcefully. Doing
so may damage the connections.
Use only the specified AC adapter (Factory Control Num-
ber: CF-AA1526) with your computer. Using an AC
adapter other than the one supplied might damage the bat-
tery and/or the computer.
When the DC plug is not connected to the computer, dis-
connect the AC cord from your AC wall outlet as well. If
the cord is kept connected, a very low level of power equiva-
lent to approximately 1.5 watts will be consumed.
Problems such as sudden voltage drops/surges may arise
during periods of thunder and lighting. Since this could
adversely affect your computer, the uninterruptible power
supply is highly recommended.
Areas other than the Display
Gently wipe other areas using a soft cloth pre-soaked in
water or a neutral cleaner and wrung out thoroughly. Do
not use solvents like benzene and thinner, nor chemical
cloths.
Surface of the LCD Panel
Soak a piece of gauze or soft cloth sufficiently in isopropyl
alcohol only, and wipe the panel gently. Using excessive
force may scratch the panel. Avoid wiping with a dry cloth,
since this can damage the surface of the polarizing plate.
Also, be sure not to use water and perfumes, as these liq-
uids can dissolve the coloration of the polarizing plate.
Maintenance
Carry the Computer Properly
Do not carry the computer without first turning off the
power.
Do not hold the computer by the LCD panel if the com-
puter is open.
Do not move the computer while a floppy disk is inserted.
Avoid Excessive Force to the LCD Panel
Do not apply excessive downward force on the display when
it is completely opened, especially when plugs and/or cables
are connected to the rear of the computer.
Avoid Extreme Heat and Cold
Do not store or use the computer in locations
exposed to heat, direct sunlight, or extreme
cold.
Avoid moving the computer between locations
with large temperature differences.

Usage
The CF-25 was developed based on thorough research into the real-world portable computing environ-
ments. Exhaustive pursuit of usability and reliability under harsh conditions led to innovations such has
the magnesium alloy exterior, MCM (multichip module) technology based cool-running Pentium
®
proces-
sor, vibration damped hard disk drive and floppy disk drive, flexible internal connections, sealed LCD and
keyboard, dust proof hinges and the revolutionary "Shirato" ruggedized LCD screen mounting system.
The CF-25's outstanding engineering has been tested using the stiff MIL-STD- 810E (for vibration and
shock) and IP (for dust and water) based procedures.
As with any portable computer device precautions should be taken to avoid any damage. The following
usage and handling procedures are recommended.
