Before Using the Handset
Use the FOMA phone’s dedicated Battery Pack P15.
Life of battery pack
p Battery packs are consumables. The usable time shortens slightly each time they are charged.
p When the usable time of the battery pack becomes half the time it was purchased, replacing is recommended because the
battery pack is nearing the end of its life. Depending on the use conditions, the battery pack may swell as it nears the end of its
life, but this is not a problem.
p The life of the battery pack may shorten if you use i- α ppli programs, talk on the videophone, watch One Seg programs and so on
for a long time during charging.
Charging
p For details, refer to the instruction manuals for the FOMA AC Adapter 01/02 (option), FOMA AC Adapter 01 for Global use
(option), and FOMA DC Adapter 01/02 (option).
p The FOMA AC Adapter 01 supports 100 V AC only. The FOMA AC Adapter 02 and FOMA AC Adapter 01 for Global use support
from 100 V AC through 240 V AC.
p The shape of the plug for the AC adapter is for 100 V AC (for domestic use). To use the AC adapter that supports from 100 V AC
through 240 V AC overseas, you need to have a conversion plug adapter that is compatible with the voltage of the country you
stay. Do not use a transformer for overseas travel to charge the battery pack.
p Even during charging, you can still answer calls if the FOMA phone is turned on. This will consume the charged amount so that charging
will take longer. Also, the standby time or talk time might be shorter if you charge the battery pack with your FOMA phone open.
p If you have a long time videophone call during charging, the temperature in the FOMA phone may rise and charging may be
suspended. In such a case, wait for a while and try charging again.
p Do not watch One Seg programs for a lengthy time during charging as the operating life of the battery might be shortened.
p Remove and insert the connector slowly and carefully, without using unnecessary force.
p Do not remove the battery pack during charging.
Do not charge for long periods of time (several days) with the FOMA phone turned on.
p If you leave the FOMA phone powered on for long periods of time during charging, you may not be able to use the FOMA phone
for long duration as expected and the low battery alarm may sound soon, because the FOMA phone receives the power from
the battery pack after charging is completed. If this happens, charge the battery pack correctly. When charging the battery pack
again, first remove the FOMA phone from the AC adapter (or desktop holder) or DC adapter and then set it again.
Estimated usable time for battery pack
(The usable time for the battery pack varies with the charging time and the remaining life of the battery pack.)
※ The continuous talk time is the estimated time that the FOMA phone can be used for calls when radio waves can be sent and
received normally.
※ The continuous standby time is the estimated time when radio waves can be received normally. The standby time could be about half of this
estimate depending on the charge level of the battery pack, function settings, other ambient conditions such as temperature, and the status
of radio waves in the area (weak or no radio waves, for instance). When you use i-mode communication, the talk/communication time and
standby time will be shorter. Further, even if you do not make calls or not execute i-mode communication, the talk/communication time and
standby time will be shorter if you watch One Seg programs, compose i-mode mail, start up a downloaded i- α ppli program or the i- α ppli
Stand-by display, execute data communication or Multiaccess, use a camera, play back music, or use Bluetooth connections.
※ The continuous talk time and the continuous standby time may be shortened depending on the network environment in the
country you stay.
※ The continuous standby time for standstill is the average number of hours you can use the FOMA phone in standstill status
when it is closed and can receive radio waves normally.
※ The continuous standby time for in motion is the average number of hours you can use the FOMA phone in the combined status
of “standstill” “moving” and “out of the service area” when it is closed, in an area where it can receive radio waves normally.
※ The One Seg watching time is the estimated time for when radio waves can be received normally with the Flat-plug Stereo Earphone
Set P01 (option) connected. The watching time might be shortened depending on the
charge level of the battery pack, function settings,
other ambient conditions such as temperature, and the status of radio waves in the area (weak or no radio waves, for instance).
Estimated time for charging battery pack
※ The charging time is an estimate of time for when empty battery pack is charged with the FOMA phone turned off. The charging
time will be longer if you charge the battery pack with the power of the FOMA phone turned on.
Charging FOMA Phone
For environmental protection, bring the exhausted battery pack to an NTT DoCoMo, dealer, or recycle shop.
