Use the Travel Charger
The travel charger operates from a 120/220 VAC wall
outlet.
1. Plug the AC plug from the desktop charger into a
standard 120 VAC or 220 VAC wall outlet.
Note: You can use your phone while charging, however, the battery
charges faster if the phone is turned off.
Battery Indicator
The battery indicator in the upper-right corner of the
display indicates battery power level. Four bars indicate
a full charge, while an empty icon
indicates an almost
empty battery. Two to three minutes before the battery
becomes too low to operate, a blinking empty battery icon
appears and a tone sounds. If you continue to operate
the phone without charging, it shuts down.
