Before Using the Handset
■ Precautions
･ If you talk on the phone or use communication, i-mode or i- α ppli for a long time while charging the battery,
charging will take longer. The battery may not be charged temporarily by temperature rise. This may also
shorten the battery pack life.
･ Insert or remove the connector straight to/from the FOMA terminal.
･ Insert or remove the connector to/from the FOMA terminal slowly and firmly without forcing it. When
removing it, be sure to press the release buttons on both sides of the connector and pull it out. Forcibly
pulling the connector could cause equipment failure.
Do not charge for longer than 1 day with the power on
The FOMA terminal uses power after charging is completed until the terminal is unplugged from the adapter. In
such a case, the AC adapter or DC adapter charges again but if the FOMA terminal is removed in the middle of
charging, the following could occur:
･ Low battery level ･ Message appears indicating that the battery runs down
･ The FOMA terminal is operational for a short time
Charging time and operation time on full charge (estimates)
*1 Estimated call time of the FOMA terminal when it can send and receive signals normally.
*2 Estimated operation time of the FOMA terminal when it is closed and able to receive signals normally. The
call time and standby time may be reduced to about half, depending on the amount of charge in the battery,
the function settings, the ambient temperature and signal conditions (radio waves do not or hardly reach).
Using i-mode communication reduces the call (communication) time and standby time. Even if you do not
make a call or use i-mode, the call (communication) time and standby time will be reduced by composing
i-mode Mail or by starting downloaded i-
α ppli or the i- α ppli standby display.
*3 Average operation time of the FOMA terminal when it is standing still, closed and able to receive signals
normally.
*4 Average operation time of the FOMA terminal that is standing still, moving and outside the service area when
it is closed and able to receive signals normally.
■ Precautions
Alternatively, if you use data communication, Multiaccess, Still/Movie Camera or FM Radio, or play video/
i-motion or music, the call (communication) time and standby time will be reduced.
