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
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.
