Precautions

The CF-25 was developed based on thorough research into the real-world portable computing environ­ments. 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
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.

Usage

Avoid Extreme Heat and Cold

Do not store or use the computer in locations
exposed to heat, direct sunlight, or extreme
cold.
A void moving the computer between locations
with large temperature differences.
Operation: 5 oC to 35 oC (41 oF to 95 oF)
Storage: -20 oC to 60 oC (-4 oF to 140 oF)

Avoid Direct Sunlight on the LCD Panel

The LCD panel should not be exposed to direct
sunlight or ultraviolet light.

A void Humidity Liquids and Dust

Do not store or use the computer in locations
exposed to high humidity, liquids (including
rain) or dust.

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.

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.

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.

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.

Maintenance

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 liq­uids can dissolve the coloration of the polarizing plate.

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.

Handling the A C Adapter

Do not twist or pull the AC power cord forcefully. Doing

so may damage the connections.

Use only the specified AC adapter (Factory Control Num­ber: CF-AA1526) with your computer. Using an AC
adapter other than the one supplied might damage the bat­tery and/or the computer.

When the DC plug is not connected to the computer, dis­connect the AC cord from your AC wall outlet as well. If
the cord is kept connected, a very low level of power equiva­lent 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.

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.

Cables

Use of an interface cable longer than 3m (118.11 inches)
is not recommended.

tings.

NOTE

The battery pack will become somewhat warm during normal use. This is not a malfunction.
The operating time may differ from the display depending on the charging and discharging

temperatures and battery wear.

CAUTION

When transporting spare batteries inside a package, briefcase, etc., it is recommended that

the batteries be stored in a plastic bag.

Exposure to strong shock (such as being dropped on the floor) can cause the battery pack to

malfunction.

Do not touch the terminals on the battery pack. Damaged terminals may cause system perfor-

mance failure.

Do not expose the battery pack to open frame.
Do not throw the battery pack into a fire or water.
Use the battery pack only with the computer for which it was designed.

Battery Power

A Shorter Than Expected Battery Drive Time

Your computer may experience a shallow charge-discharge cycle characterized by
computer operation for a short period of time followed by battery charging. Repeti­tion of such cycles will decrease your battery’ s operating time temporarily . The above
should be kept in mind if you decide to run the computer off the battery after it has
been running off the AC adapter for an extended period of time.
The computer automatically determines the need for battery refreshing. In such cases,
the screen will display a message reminding you to refresh the battery , after the com­puter has been started up. In this case, the battery indicator blinks in green to indi­cate the need for battery refreshing. Refreshing is commenced after any key is pressed.
Also, if you leave a fully charged battery for 2 to 4 weeks in temperatures above 35°C
(95°F), the battery’s operating time may decrease temporarily.
These conditions are not due to a fault in the battery. Normal performance can gen­erally be restored by fully charging and then discharging the battery two or three
times in succession. In order to fully discharge the battery in a short period of time, a
battery refresh tool (BATTREF.COM) is provided

battery operating time may vary drastically depending on the types of installed op­tions.

NOTE

Replace the battery pack if the amount of time the computer can be operated on a full charge
drops to approximately one half of the normal duration.

( P.17). Please note that the

Hints on How to Use Battery Pack

If you plan to leave the computer idle for an extended period of time (approximately
two months or more), first discharge the battery using the “refresh” method, next,
charge the battery pack until the charge level reaches 50%, then remove it from the
computer and store it in a cool, dry place. (Refer to the Operating Instructions for
information on removing the battery.)
Excessive discharging of the battery can occur if it is left in the computer for ex­tended periods of disuse, possibly shortening its service life or causing damage to
the computer. (Note that the battery will not discharge if the AC adapter is left
connected, so it does not have to be taken out in such cases.)

14

Replacing

Removal

Battery Power

The battery pack is an item that at some point will require a replacement. If the
usage time of a battery pack becomes noticeably short, and repeated recharging does
