1. After installation and initial testing with tuning forks,
the FalconHR should be driven at a constant speed,
between 30 and 70 mph (48 and 112 km/h). Press the
PAT SEL switch on the remote control twice. “Snc”
will appear in the TARGET window and patrol speed
will appear in the PATROL window.
2. Verify the patrol speed displayed matches the
speedometer reading, and press the LOCK/REL switch.
This tells the DSP processor that the current
speedometer reading and the Doppler patrol reading
agree, within speedometer tolerance limits.
3. Within two (2) seconds, a synchronization number will
appear in the LOCK window. Typically this number
will be around 50 for Ford products. This indicates the
FalconHR is reading and comparing the speedometer
speed input and the true Doppler patrol speed.
NOTE: Only the actual Doppler signal is used for
the Patrol Speed. The speedometer input is
used only to steer or guide the DSP to search
for the Patrol Doppler signal in a specific
area, ignoring signals in other areas.
4. During normal operation, at patrol speeds below the
minimum limit of 10 mph, 16 km/h, or when a
“groundspeed” Doppler signal cannot be found, the
PATROL window will display two dashes (--),
indicating that the speedometer speed is being received
but a patrol speed cannot be found or displayed. As an
example, when a patrol vehicle is slowing down and the
speed drops below the minimum speed, dashes will be
displayed.
