Once your phone is on, it may display “Searching...”
When your phone finds a signal, it enters standby
mode – the phone’s idle state. At this point, you are
ready to begin making and receiving calls.
If your phone is unable to find a signal after 15 minutes
of searching, a Power Save feature is automatically
activated. When a signal is found, your phone
automatically returns to standby mode.
In Power Save mode, your phone searches for a signal
periodically without your intervention. You can also
initiate a search for Boost service by pressing any key
(when your phone is turned on).

Removing the Battery
1. Make sure the power is off so that you don’t lose
any stored numbers or messages.
Tip: The Power Save feature conserves your battery power
when you are in an area where there is no signal.
WARNING: Use only Boost-approved or Samsung-approved
batteries and chargers with your phone. The
failure to use a Boost-approved or Samsung-
approved battery and charger may increase the
risk that your phone will overheat, catch fire, or
explode, resulting in serious bodily injury, death,
or property damage.
