~ Charging the Battery
A flashing red light indicates that the battery level is very
low : the battery should be recharged because, if the level
is too low, it may shorten the life of the battery.
Connect the charger to a power outlet and the micro UsB
connector to the phone’s UsB port.
The phone’s status indicator changes to red, indicating that
the device is charging.
Once the phone has finished charging, the status indicator
changes to green and you should unplug the charger.

section.
