When the battery charge is getting low, the “Battery low. Please
recharge” message is displayed on your screen, and the phone
sounds a warning tone. When the battery has become too weak
to operate your phone, the message “Switching off. Please
recharge” is displayed on your screen.

Note:

Long backlight settings, searching for service, and vibrate mode

affect the battery’s talk and standby times.

Tip:

Be sure to watch your phone’s battery level indicator and charge the

battery before it runs out of power.

Installing the Battery

To install the battery, replace the battery, or to access your
phone’s ESN (electronic serial number), you must first remove
the phone’s back cover.

Note:

Turn the phone off before removing the phone cover.

To remove the back cover, press the release button, press your
thumb against the thumb grip, and slide the entire back cover
up and over the whip antenna.

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.

Removing

the Battery

To remove your battery, follow these easy steps:

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, pressing your thumb against the thumb grip, and
sliding the entire back cover up and over the whip antenna.

3. Pull upward on the lower end of the battery with your

finger tip and remove the battery from the phone at a
45-degree angle.

Charging the Battery

Your PCS Phone comes with a rechargeable battery. You should
charge the battery as soon as possible so you can begin using
your phone.

Keeping track of your battery’s charge is important. If
your battery level becomes too low, your phone
automatically turns off and you will lose all the
information on which you were just working. For a
quick check of your phone’s battery level, glance at the
battery charge indicator located in the right side of your
phone’s display screen.

Always use a Sprint-approved desktop charger, travel charger, or
vehicle power adapter to charge your battery.

Warning!

Only use batteries approved by Sprint. Using the wrong battery

charger could cause damage to your phone and void the warranty.

Using the Charger

To use the charger provided with your phone:

1. Install the phone battery in the phone.

2. Plug the prongs of the adapter into an electrical outlet.

3. Plug the round end of the AC adapter into the desktop

charger and insert the phone into the charger slot.

– or –

Plug the adapter directly into the charger jack on the phone,
if the charger stand is not used. (If the phone is on, the
screen briefly displays a “Charging” notification followed
immediately by a scrolling battery strength indicator. If the
phone is off, the screen displays “Phone off. Battery
charging”.)

4. When the battery is fully charged, unplug the phone from

the charger. (If the phone is on, the battery strength
indicator stops scrolling. If the phone is off, the screen
displays “Phone off. Charge completed”.)

It takes approximately 4 hours to fully recharge a completely
rundown battery. With the Sprint-approved LiIon battery, you can
recharge the battery before it becomes completely run down.

Warning!

Unplug the charger when not in use. Do not leave the battery

connected to a charger for longer than a week, since overcharging may
shorten its lifetime. If left unused a fully charged battery will discharge
itself over time.
