Before Using the Handset
Getting the best out of your battery pack
Use the approved Battery Pack N16 for the FOMA terminal.
If you use the FOMA terminal overseas, take the FOMA AC Adapter 01 for Global use/FOMA AC
Adapter 02 with you. Before using the FOMA AC Adapter 01 for Global use/FOMA AC Adapter 02,
check the voltage available in a country or area you will stay.

Battery life
a
Batteries have a limited service life. Like all rechargeable batteries, the amount of usable time
decreases every time the battery is recharged.
a
When a fully charged battery pack only lasts half as long as when it was new, it is time to replace
it with a new one. Depending on the conditions under which it is used, the battery pack may
swell as the life comes close to the end, but this causes no problem.
a
Using i-
α
ppli or videophone for a long period of time with the FOMA terminal being charged may
shorten the life of the battery pack.
■
Charging
a
For details, refer to the manuals for FOMA AC Adapter 01/02 (optional) and FOMA DC
Adapter 01/02 (optional).
a
Attach the battery pack to a FOMA terminal to charge the battery.
a
You can receive calls while charging if a FOMA terminal is turned on. However, the battery level
will fall during calls and the time required for charging will increase. Charging time will also
increase if "Charging" in "Backlight" is set to "All time ON".
a
When plugging in or out the connector, do it slowly and securely not to apply excessive force.
a
When you make a call or perform packet communication in a high temperature environment, the
FOMA terminal's temperature may rise and the charging may be stopped. In this case, stop any
running functions and wait for the temperature to fall before you retry charging.
■
Do not charge the battery pack for a long period of time (several days) with the FOMA terminal turned on
a
If you charge the battery pack for a long period of time with the FOMA terminal turned on, power
to the FOMA terminal will be supplied from the battery pack once charging ends. As a result,
you will only be able to use the FOMA terminal for a short period of time and the low voltage
alarm may sound immediately. In this case, recharge the battery pack correctly. Disconnect the
FOMA terminal from the AC adapter (or desktop holder) or DC adapter and then attach it again
for recharging.
■
Battery duration (The battery duration varies depending on the charging time or deterioration of the battery)
a
Continuous talk time is an estimate of the talk time at maximum power when radio reception is
normal.
a
Continuous standby time is an estimate of the standby time when the FOMA terminal is folded
and remains within an area where radio reception is normal. In certain circumstances, talk (or
communications) and standby times may drop to as low as half the times shown due to the
battery charge, function settings, temperature, or radio reception in the area (weak or no
reception). Talk (or communications) and standby times will be less when you use i-mode.
These times will also be less when you compose an i-mode message, run downloaded i-
α
ppli,
launch the i-
α
ppli standby display or play music even without making calls or using i-mode.
a
Talk (or communications) and standby times will also be less when using i-mode or data
communication, performing Multi access, using the camera, playing movies, i-motion or music.
a
Continuous standby time for stationary is an average estimate of the standby time when the
FOMA terminal is folded and remains within an area where radio reception is normal.
a
Continuous standby time in transit is an average estimate of the standby time in "stationary", "in
transit" and "out of the service area" states when the FOMA terminal is folded and remains
within an area where radio reception is normal.
a
Talk (or communications) and standby times will also be less when you insert a microSD
memory card, run data communication or multi access, or use the camera or light.
To protect the environment, take used battery packs to NTT DoCoMo, the
agency, the recycle shop, etc.
