Note: Backlighting, searching for service, and vibrate mode use reduce
the battery’s talk and standby times.
Tip: Be sure to charge your phone’s battery, and watch the battery
strength indicator to ensure that the levels are okay.
Installing the Battery
Your PCS Phone comes with a Li-Ion battery. To install or replace the
battery, or to access your phone’s ESN (electronic serial number), you
must first remove the phone’s back cover. To do so, press the release
button, press your thumb against the thumb grip, and slide the entire
back cover up and over the whip antenna.
Tip: Always make sure the power is off before removing the phone cover.
To install the battery:
1. Insert the battery at a 45-degree angle with the label side facing up
into the cavity on the back of the phone. The metal contacts must be
aligned with and connected to the metal prongs.
2. Press down on the battery until it snaps into place.
Removing the Battery
To remove the battery:
1. Make sure the power is off so that you don’t lose any stored numbers
or messages.
2. Remove the back cover by pressing and holding the release button
and sliding the entire back cover up and over the whip antenna.
