Signal Strength
The call quality depends on the signal strength in
your area. The current signal strength is displayed on
the screen as the number of bars next to the signal

strength. If the signal quality is poor, move to an
open area. If you are in a building, the reception may
be better near a window. For maximum reception,
make sure that the antenna is fully extended.
