The yellow middle window performs two functions; an icon located directly below the
window indicates each. If the window is being used to display a locked target speed, a
T-lock (T ) icon is lit. Only the speed of the strongest target can be locked. If the middle
window is being used to display the speed of the fastest vehicle (fastest mode), a FAST icon
is lit. General error conditions (Err) are also indicated in this window. When “rFi” is
indicated in the leftmost window, this window will display the relative strength of the signal
causing the interference.
The green window on the right side of the display shows the PATROL vehicle’s speed in
moving mode and remains blank in stationary mode. The speed displayed in this window
should correspond with the patrol vehicle’s speedometer. If a low voltage condition occurs,
“Lo” will appear in this window.
Doppler audio
The BEE III features a speaker on the front panel for Doppler audio. The BEE III's audio is
derived directly from the received Doppler signal (not synthesized) and is useful as an aid in
target identification. The loudness is proportional to the strength of the received signal and
increases as the target vehicle approaches. The pitch of the audio signal increases with
higher closing speeds. The Doppler audio always corresponds to the strongest target, even
when the radar is in fastest mode.
In stationary strongest mode (no specific direction selected) the Doppler audio heard is that
of targets traveling in both same and opposite directions. In directional stationary mode
(only same or opposite direction targets selected) the Doppler audio heard will be from the
selected direction only.
Display dimming and infrared remote sensor
A photocell located on the display panel automatically adjusts display brightness to ambient
light conditions. An infrared sensor also located on the display panel receives commands
from the optional wireless remote.
Power button
This button controls power for the BEE III radar. When the BEE III is turned off, the radar
retains all previous settings (volume, mode, etc.) with the exception of range, which defaults
to maximum. When the unit is next powered on, speed displays are blank and the unit starts
in standby mode.
