Battery charging
Using any AC adapter, vehicle power adapter (option) or dual tap (option) not specified by NEC for use with this phone can be dangerous and may
invalidate any warranty and approval given to the cellphone. Do not leave the charger connected to the mains supply when it is not in use.
Do not try to charge the battery if the ambient temperature is below 5°C (41°F) or above 35°C (95°F).
If the phone does not respond, please wait for a few minutes. The charging will then start.
If you use the phone while charging, handle the phone carefully since the cable or adapter is connected.
If you make/receive a call while charging, the charging may temporarily be interrupted.
Charging takes approximately 3 hours with your phone turned off.
Even if the phone remains connected to the charger, battery residual capacity may decrease when the phone is used for video recording, playing or other battery
consuming operation.
IMPORTANT BATTERY CHARGING INFORMATION
Charging a very low battery
The battery's charge continues to drop after the low battery warning is displayed. In extreme cases where the battery is left uncharged for some considerable time
after this warning, a trickle charge is used to slowly top-up the battery to the safe level at which the fast charging can begin. The phone can be in trickle charge for
a few minutes before the fast charging starts.

Standby and talk times

Your phone works closely with the network you are using to provide the services you need, and the standby and talk times achieved will depend on how you use the
phone and choices made by the network operator.
In particular, factors such as your location within the network, the frequency at which this location is updated, the type of SIM card you have, your reception of area
messages or cell broadcast messages and the use of full rate or enhanced full rate speech, will affect both standby and talk times.
