Preliminary Check 23
■ Precautions for charging
Q The included AC adapter plug shape is designed for AC100V (national
specification). To charge the device abroad, a corresponding plug
adapter is required. Do not use an adapter transformer for overseas
trip.
Q If you charging the FOMA terminal while using it, full charge may take
more time or charging may not be completed. Continuous use of
functions consuming large current - data communication and voice
call, etc. - may decrease battery level, leading to battery shortage
even during charging.
Q If you start charging when the battery is empty, the device may not be
started promptly after power ON operation. In this case, start charging
with the FOMA shut off and turn it on after a while.
Q When the temperature failure icon appears in the status bar, functions
presented in the notification panel are disabled.
Q When the charging failure icon appears in the status bar, open the
notification panel and take appropriate actions.
Q If you leave the FOMA terminal being charged for long time, the
FOMA terminal consumes power from the battery pack after
completion of charging, so uptime may be shortened and battery
shortage alarm may be generated soon. In such case, recharge the
device in appropriate manners. For recharging, disconnect the AC
adapter cable from the FOMA terminal and then reconnect them.
■ Battery pack operating file
Q Battery pack is consumable. Uptime is gradually decreased with
repeated charging.
Q When its uptime from fully-charged state is decreased to about a half
of that in the factory state, the battery pack is dying so you should
replace with new one. Depending on how the battery pack is used, it
might swell as its operating life becomes short, but this is not a
problem.
Q Long-time 1Seg watching during charging may shorten the battery
pack operating time.
