Operations and precautions for charging
When charging starts, a charge start alert sounds, the light turns on and the battery
icon on the display blinks. When charging is over, a charge completion alert sounds,
the light turns off and the battery icon stops blinking.
Also, deterioration of the battery pack is measured at the completion of the battery
charge. For the deteriorated battery, "Time to exchange battery" appears on the
stand-by display after you disconnect the terminal from the AC adapter, desktop
holder or DC adapter. You can also check the deterioration by menu operations.

When starting the battery charging, the light turns on in red. In some
environments, the light may not light immediately when charging starts; this is
normal and not a malfunction. However, if the light does not turn on after a while,

then connect it again to start charging. Contact the sales outlet such as docomo
Shop if the light does not turn on for a while after charging starts.

If you receive mail or shoot an image while charging, the light turns on
temporarily in a different color, but it is not a failure. It turns on in red after a while.

When installing the fully charged battery pack to FOMA terminal and connecting
it to the AC adapter, desktop holder or DC adapter, the light may turn on for a

remaining battery level.
(Battery level 5) : Ample charge (81-100%).
(Battery level 4) : Slightly low charge (61-80%).
(Battery level 3) : Low charge (41-60%).
(Battery level 2) : Very low charge (21-40%).

INFORMATION
･
Battery level information is corrected to improve the battery level accuracy. Corrected
information is reset when battery pack is replaced because it is the information unique
to the battery pack. Therefore, error may temporarily become larger immediately after
the battery pack is installed.
･
When the battery level is displayed in a percent figure, it may be increased or decreased
approximately by 10% in the process of correction, however, it is not a failure. Note
that, when the correction is made with the battery level approximately 10%, it may
suddenly become 0% and battery alarm may sound.
･
The error of the battery level may temporarily become larger in the following cases.
- An old battery pack (heavily used battery pack) is used.
- A new battery pack and an old battery pack are alternately used.
- Difference in temperature between a battery pack and FOMA terminal is considerable when used.
- A battery pack left for a long time is used.
