Using The Battery; Installing And Removing The Battery; Charging The Battery - Sanyo Sprint SCP-4000 User Manual

Using the battery.

Your Sprint PCS Phone comes with a rechargeable battery.
Remember to fully charge your battery as soon as the charge
becomes low in order to maximize your talk and standby times.

Installing and removing the battery.

The battery snaps easily onto the back of the phone (bottom end
first) for quick installation and removal. Make sure to turn the
power off before removing the battery. Otherwise, you could lose
stored numbers and messages.

Charging the battery.

You can tell whether or not your battery needs to be recharged by
checking the upper-right corner of your Sprint PCS Phone's
display. When the battery charge level gets low, the battery icon
will blink and the phone will sound a tone. If the battery
level gets too low, the phone will turn off automatically. A series of
alert tones will sound just before the phone turns itself off. If this
happens, unfortunately, you'll lose whatever you were just doing.
So watch that indicator and make sure your battery charge level is
okay.
