Use only the specified AC adaptor (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 benzine and thinner, nor chemical

cloths.

However this computer is designed to prepare for shock, liquid and dust, please read the

above precautions carefully on how to handle your computer.

CAUTION

LCD Panel

The LCD panel should not be exposed to direct sunlight

or ultraviolet light.

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.

Carrying

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.

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.

Battery Power

This computer contains the following two types of batteries.

Main Battery: (Ni-MH rechargeable battery pack)

Removable battery that runs the computer without the AC adapter.

Clock Battery: Battery that is housed inside the computer and maintains the clock and set-

tings.

An incorrect display may result if the main battery is installed or removed while the power to

the computer is switched off or while the computer is in the suspend (hibernation) mode.

The four indicators blink when the RESET button is pressed or when a battery pack has been

replaced.

NOTE

The battery pack will become somewhat warm during normal use. This is not malfunction.

The operating time may differ from the display depending on the charging and discharging

temperatures and battery wear.

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 flame.

Do not throw the battery pack into a fire or water.

Use the battery pack only with the computer for which it was designed.

Do not directly connect the negative and positive terminal on the battery pack.

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. Repeti-

tion 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 com-

puter has been started up. In this case, the battery indicator blinks in green to indi-

cate 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 gen-

erally 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

( P.17). Please note that the

battery operating time may vary drastically depending on the types of installed op-

tions.

Battery Power

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.

NOTE

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), discharge the battery first by using the “refresh” method,

remove it from the computer and store it in a cool 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 ex-

tended 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.)

Turn the computer over.

Use a screwdriver to loosen the two screws located

toward the front of the computer.

Removal

Replacing

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

not restore its performance, the battery pack should be replaced with a new one (part

number: CF-VZS250 or CF-VZS251).

Remove the cover.

Turn the computer off by pressing and holding the power

switch in the 'ON' position simultaneously.

Slide the battery pack toward the outside edge to remove it.

Battery Power

NOTE

Always switch the computer off and disconnect the AC adapter before replacing a battery

pack.

The battery pack may malfunction if it is exposed to strong shocks. Caution should be exercised.

Mounting

Drop a new battery pack into the pocket.

Slide the battery pack inward until it is firmly in place.

Replace the cover and tighten the two screws.

NOTE

If the battery pack is subjected to temperatures outside of the specified 5°C to 35°C (41°F to

95°F) range, charging will not commence. Under this circumstance, the battery indicator will

blink for 5 seconds. Charging will commence automatically once the temperature falls within

the allowable range. The battery temperature may rise as high as 60°C (140°F) during charging.

Recharging

The battery automatically is charged when the AC adapter is plugged into a socket.

Rapid charging commences when the POWER switch is turned off. Normal charging

takes place when the POWER switch is turned on.

Charging will terminate (Battery indicator changes from orange to green) automati-

cally when the battery is fully charged. In this state, it will remain fully charged as

long as the AC adapter is connected.

The AC adapter will become warm during charging or while in use; this is perfectly

normal.

CAUTION

Always allow the battery to become completely discharged (low battery alarm sounds) before

recharging .

Since the battery is not pre-charged, be absolutely sure to charge these batteries before using

the computer for the first time. Charging commences automatically after the AC adapter is

connected.

A new battery or a battery that has not been used for a prolonged period of time will not be

fully charged after it has been charged/recharged only once.

It is recommended not to charge a battery that has not been completely discharged first (low

battery alarm sounds).

Do not charge a battery in any other computer or by using a recharger other than the one

specified.

When the duration of a battery’s operation has fallen by half or so, repeat the battery refresh
