Use the Battery pack N16 specified for the FOMA
terminal.
■
Battery pack life
• The battery pack is consumable. The amount of
usable time decreases every time the battery pack
is recharged.
• When a fully charged battery pack only lasts half as
long as it did at the time of purchase, the battery
pack life is almost over, so it is recommended to
replace it with a new one. When the life of the
battery pack is near end, the battery pack may
expand a little according to the usage condition, but
this is not a malfunction.
• The battery pack life may be shortened if i-
α
ppli,
videophone or 1Seg is used for a long time while
charging.
■ Battery pack charging
• For details, refer to the manuals for the FOMA AC
Adapter 01/02 (optional), FOMA AC Adapter for
Global use 01 (optional) and FOMA DC Adapter
01/02 (optional).
• FOMA AC Adapter 01 supports voltage of 100V AC
only. FOMA AC Adapter 02 and FOMA AC Adapter
01 for Global use support voltage from 100V AC to
240V AC.
• The plug shape of the AC adapter is for 100V AC
(domestic). For overseas use with the AC adapter
supporting voltage from 100V AC to 240V AC, the
compatible conversion plug adapter is required. Do
not charge the battery using the transformer for
travel.
• When charging the battery pack, the battery pack
must be attached to the FOMA terminal.
• You can receive calls during charging if the FOMA
terminal is turned on. However, the battery level will
fall during the call and the time required for
charging will increase. Charging time also
increases when “Charging” of “Backlight” setting is
set to “All time ON”.
• When plugging in or out the connector, do it slowly
and securely not to apply an excessive force.
• When the illumination lamp and “ ” flash,
charging is not available due to temperature
monitoring until the terminal temperature cools
down enough for charging.
• When you make a call or perform packet
communication during charging in a high-
temperature environment, the FOMA terminal’s
temperature may rise and the charging may be
stopped. If this occurs, stop a running function and
wait for the temperature or the FOMA terminal 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
• 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 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, then set
it again for recharging.
■ Battery pack charging time
The charging time is the time required to charge a
completely empty battery pack, with the FOMA
terminal power OFF.
■ Battery usage time (The duration varies
depending on the charging time and the
deterioration of the battery pack.)
• The continuous standby time in stationary is the
average usage time when the FOMA terminal is
folded and standing still while radio waves can be
normally received.
• The continuous standby time in moving is the
average usage time when the FOMA terminal is
folded under condition of “stationary”, “moving”,
and “out of service area” within the area where
radio waves can be normally received.
To protect the environment,
take used battery packs to NTT
DOCOMO, the agency, the
recycle shop, etc.
