1.
Lay the probes on top of the ground perpendicular to the driveway 4 feet (1.2m) apart. Then
drive a car by the probes to test the position. You should hear a chime from the receiver.
NOTE:
The tune selected for the “A” button corresponds with the car passing Probe A then
Probe B. The tune selected for the “B” button corresponds with the car passing Probe B then
Probe A.
(See diagram on Page 8)
2. After you have tested the location of the probes to make sure they detect properly, you can
commit to burying the probes and wire.
3. The probes need to be buried perpendicular to the flow of traffic and should be separated by
4 ft. (1.2m). As a general rule, the vehicle should pass Probe “A” first then Probe “B” as it is
entering the driveway.
4. Bury the wire to a nearby tree or post and mount the transmitter box about 4 to 5 feet
(1.2 to 1.5m) off the ground.
Note:
Although the maximum wireless range is about one mile, obstructions such as hills, trees, metal siding,
and stucco can all reduce the range. Metal posts may interfere with the transmitter’s radio signal.

ADJUSTING THE SENSITIVITY
The small dial above the terminal block for Probe A and Probe B is the sen-
sitivity adjustment. If you are having difficulty detecting vehicles, rotate
the dial clockwise (CW) to increase the sensitivity. If you are experiencing
false signals, rotate the dial counter clockwise (CCW) to decrease the
sensitivity.
SPEED CONTROL
SLOW-will detect vehicles travelling from approximately 2 to 35 mph. Use the slow
setting if the main road has high speed truck traffic.
FAST-will detect vehicles travelling from approximately 2 to 45 mph.
