Before Using the FOMA Terminal
Battery Pack
To make full use of the FOMA terminal, make sure to use the Battery Pack SO02.
■ Life of the battery pack
The battery pack is a consumable part. The life of any rechargeable battery decreases each time
it is recharged.
When the duration of operation becomes less than half in comparison with a new battery pack,
the life of the battery pack can be considered over.
(The average life of a battery pack is about one year. However, depending on the frequency of
use, the life may become shorter.)
Return all spent battery packs to NTT DoCoMo or a dealer, or a recycling
shop to protect the environment.

Charging the FOMA Terminal
At the time of purchase, the battery pack is not fully charged. Make sure to fully charge
the battery pack before using the FOMA terminal for the first time.
About Charging the FOMA Terminal

Make sure to attach the battery pack in the FOMA terminal before connecting it to the optional AC Adapter,
Desktop Holder, or DC Adapter. If the battery pack is not attached, the FOMA terminal cannot be charged.

If you use a function such as the videophone, data communication, and i- α ppli while charging the battery, the
charging may stop because of high temperature of the FOMA terminal. The charging may not even start if the
FOMA terminal is in high temperature. Wait until the temperature of the FOMA terminal falls and restart charging.

If the charge indicator of the FOMA terminal flashes in red, wait until the temperature of the FOMA terminal falls
or remove the battery pack and attach it back again.
If it continues to flash in red, the battery pack may be defective. Stop charging immediately and contact our
service counter (DoCoMo shop, etc.).

Do not charge the battery pack for a long period of time (more than 24 hours) with the FOMA terminal powered
on. If the FOMA terminal is powered on when charging is completed, the battery level decreases. This causes
the FOMA terminal to restart charging. If you remove the FOMA terminal while it is recharging, the following
conditions may occur.
- The battery level is low. - The battery alarm sounds. - The operation time is short.
■ Estimated charging time/Battery time
Charging time (AC adapter) Continuous call (communication) time Continuous stand-by time
About 140 minutes Voice call : About 160 minutes
Videophone call : About 90 minutes
Stationary state : About 600 hours
Moving state
: About 450 hours

The charging time is an estimated time for charging when the battery pack is empty and the FOMA terminal
is powered off. When charging with the FOMA terminal powered on, the charging time becomes longer.

The continuous call time is an estimated time for a call when the FOMA terminal can send/receive radio
waves properly.

The continuous stand-by time is an estimated battery time available on the FOMA terminal when it is folded
and can receive radio waves properly. The continuous stand-by time during the stationary state indicates the
average battery time available on the FOMA terminal that is placed stationary when it is folded and can receive
radio waves properly. The continuous stand-by time during the moving state indicates the average battery time
available on the FOMA terminal that is placed in mixture of the following states: “stationary”, “moving”, and
“outside of the service area” when it is folded and within an area where it can receive radio waves properly.

Note that the call (communication) time and stand-by time may be reduced to about half of the time indicated
above depending on the battery charge condition, function settings, operating environment such as
temperature, and radio wave condition in the area where a call is placed (outside of the service area or area
with weak radio wave condition). Similarly, the call (communication) time and stand-by time become shorter
than the above when you use i-mode communication. Besides calls and i-mode communication, the battery
time is also reduced when you are composing i-mode mail, starting a downloaded i-
α
ppli or i-
α
ppli stand-by
display, performing data communication, executing multiaccess, and using the camera or MUSIC Player.
