CHARGE THE BATTERY
1. Plug the charger into a wall outlet.
2. Connect the charger to the phone. When done, unplug the charger from the
phone, then from the wall outlet.
If the battery is completely discharged, it may take several minutes before the
charging indicator is displayed.
Tip: You can use USB charging when a wall outlet is not available. Data can be transferred
while charging the device. The efficiency of USB charging power varies significantly, and it
may take a long time for charging to start and the device to start functioning. Make sure
your computer is switched on.
SAVE POWER
To save power:
1. Charge wisely: always charge the battery fully.
2. Select only the sounds that you need: mute unnecessary sounds, such as keypad
sounds.
3. Use wired headphones, rather than the loudspeaker.
4. Change the phone screen settings: set the phone screen to switch off after a
short time.
5. Lower the screen brightness.
6. When applicable, use network connections, such as Bluetooth, selectively: switch
the connections on only when you are using them.
