25 The Basics
Installing the Battery and microSD Card
NOTE It is important to fully charge the battery before initial use of the phone.
The phone comes with a rechargeable battery. Keep the battery charged
while not in use in order to maximize talk, use, and standby time. The
battery charge level is shown at the top of the screen.
Installing the battery
1 Press the bump on the
bottom part of the cover
and slide the battery
cover upward to remove
from the back of the
phone.
2 Align the battery with
the terminals near the
bottom of the phone,
then press the battery
into place.
3 Replace the battery
cover over the back
of the phone (as
demonstrated). Slide the
battery cover downward
while applying steady
downward pressure until
it clicks into place.
Removing the battery
Turn the power off. Remove the battery cover (as demonstrated in the
previous instructions). Then use the fingertip cutout at the top of the
battery compartment to lift the top edge of the battery out.
