Precautions on the Battery Pack
Be sure to use the battery pack dedicated to the FOMA
phone.
a
Battery life
• Batteries are consumables. The usage time of all
chargeable batteries shortens slightly each time they
are charged. The battery’s life is considered to be
exhausted when the usage time of the battery after
charging is about half the time it was at purchase.
(The life of the battery is about 1 year. However, it
may be shorter if used very frequently.)
a
Do not charge for long periods of time (several days)
with the FOMA phone turned on.
• Do not leave the FOMA phone power on for long
periods of time while charging. Otherwise, when
charging finishes, the FOMA phone will attempt to
receive power from the battery so that when you
actually use the FOMA phone, you will be able to do
so for just a short amount of time before the battery
alarm sounds. If this happens, charge the battery
correctly. When charging the battery again, first
disconnect the FOMA phone from the AC adapter
and then set it again.
a
Estimated usage time for battery
The usable time of the battery varies depending on the
usage environment or its remaining life.
• Continuous talk time is the estimated time when radio
waves can be sent and received normally.
• Continuous stand-by time is the estimated time you
can use the FOMA phone in motion when it is closed
and can receive radio waves normally. The standby
time could be about half of this estimate depending
on the battery level, function settings, other ambient
conditions such as temperature, the status of radio
waves in the area (weak or no radio waves, for
instance) and the status of the network of the country
in which you stay. The continuous standby time will
be shorter if you don't insert the UIM. When you use
i-mode communications, the talk/transmission time
and standby time will be shorter. Further, even if you
do not make calls or perform i-mode communication,
the talk/communication time and standby time will be
shorter if you compose i-mode mail, start up a
downloaded i-appli.
