USB cable to the charging accessory port on your phone and the
other end to a bus-powered USB port on your PC.
NOTE Low-power USB ports are not supported, such as the
USB ports on your keyboard or bus-powered USB hub.
Battery Temperature Protection
If the battery gets overheated, the phone will automatically turn
off. When you turn the phone back on, a message pops up
alerting you that the phone was powered off for your safety.
Battery Charge Level
You can find the battery charge level
at the top right of the
LCD screen. When the charge level becomes low, the battery
sensor sounds a warning tone, blinks the battery icon, and/or
displays a warning message. As the charge level approaches
empty, the phone automatically switches off without saving.
Signal Strength
Call quality depends on the signal strength in your area. You can
tell how much signal strength you have by the number of bars
next to the signal strength icon
: the more bars, the
stronger the signal. If you're having problems with signal quality,
move to an open area or, when inside a building, try moving near
a window.
