The empty battery icon
Two to three minutes before the battery charge level gets too low to operate the
phone, the battery sensor will let you know by blinking an empty battery icon
( ), and sounding a tone. If you continue to operate the phone without
charging the battery, the phone will automatically turn off. If this happens, your
wireless call will be terminated. However, if you plug into a charging device,
you can continue your call. Be sure to monitor the battery strength icon and
make certain your battery is adequately charged.
