The following screen displays:
Speed Test Dist

The Pro-Lite achieves a satisfactory calibration check if
the reported speed is within +/- 1 unit (simulated MPH) of
twice the actual target range difference. For example, if the
targets were placed at exactly 80 feet and 55 feet, with a
final separation of 25 feet, the final speed-reading on the
Pro-Lite must be 49, 50, or 51. This assumes the target
has moved this distance in 1/3 second. Other range
differences can work. The proper speed is 2 x differential
distance.
If the Pro-Lite does not pass the test, recheck the target
mounts, distances, aiming and repeat the test. If the unit
fails, contact Kustom Signals Customer Service.
After completion of the test press ESC to return to the
default-operating speed mode.
