Signal Strength Display

When a radar signal is detected the audio alerts have
a Geiger counter-like pattern to help you determine
the strength of the radar source; the faster the
beeping the stronger the radar signal. At the same
time the audio is reporting, the display illuminates the
band identification Icon and relative signal strength
from 1 to 9.
1 = weak signal, 9 = strong signal
