35 mph neighborhood speed limit
Set the "MS" (the radar detected Minimum Speed limit) at 5 mph, the
"SLOW DOWN" message at 35, "Flashing Speed" at 40mph, the "Red and Blues"
at 50 and the Blanking Speed at 60. This is what will happen: Oncoming vehicles
speeds will be shown on the sign traveling from 5 to 34 MPH. If the vehicle is
traveling 35 to 39, the SLOW DOWN message will flash. Between 41 and 49, their
speed will be displayed while flashing. Over 50MPH, the display will show the
Red + Blue flashing lights pattern. At 60 and above, the display is blank. As the
vehicle slows, the appropriate "Violator Alert" will show for their speed until they
reach 34 MPH where their speed is displayed normally.
School Zones
Set the "MS" (the radar detected Minimum Speed limit) at 15 mph (so drivers in a
school zone obeying the speed limit are not distracted), the "Flashing Speed" at
16mph and the "Blanking Speed" for 40mph. This is what will happen: For speeds
under 15 MPH, no speed will be displayed. The display will flash the speed for
vehicles traveling between 16 and 39 MPH. No speed will be displayed above 40
MPH.
Open Road
Set the "MS" (the radar detected Minimum Speed limit) for 45mph, the
"Slow Down for 70mph, "Red and Blues" flashing pattern for 75mph,
"Flashing Speed" for 65, and the "Blanking Speed for 85 (to prevent vehicles
speeding by the sign to see how fast they can go). This is what will happen:
Normal vehicles will just see their speeds from 45 to 65 MPH. Vehicles moving at
66 to 69mph will see their over-speed flash. If they travel over 70 mph, the red
"Slow Down" message will flash. Vehicles speeding over 75mph will see the "Red
and Blues" flashing lights pattern. No speed will be displayed at 85mph or above.
9. RESULTS
The readings from the radar unit are filtered. The radar unit is very sensitive, so for
continuity of the oncoming driver, not every reading may be displayed. If there is a
difference between vehicle speeds of more than 3 miles per hour per second (extreme
acceleration or deceleration), the display will simply hold the last recorded speed for a
few seconds rather than jumping back and forth between speeds. A couple of examples:

Traffic Set-Up Examples
If a vehicle is traveling at 35mph and the car behind him is traveling at
40mph, the sign will display the first vehicle at 35 until it passes. The
first vehicle's speed will show for 1-1/2 seconds after it passes, so the
radar can establish and display vehicle two's speed at 40mph.
If a vehicle accelerates towards the sign from a stop at greater than 3
miles per hour per second, no speed will be displayed. If a vehicle
accelerates at 3 miles per hour per second or less, the sign will display
the speed as it increases.
