Operating Procedure For Bee Iii Radar

Would anyone know the correct operating procedure for a MPH Bee III Radar ? Also is visual identification necessary before the radar is used and how long does the whole procedure take ? i.e from the time the officer first spots you (either visually or through the radar) until the time he gets an accurate speed reading on the radar ?

Just for clarity, all radar is "supposed" to be used for is to confirm what the officer has witnessed. In other words, the officer witnessed a vehicle travelling at a high rate of speed, estimates it, then pulls the radar trigger to confirm the visual..... BTW, radar does not have sighting scope.... as for testing, the self check of the internal circuitry is sufficient for the courts.... try googling if you want for the user manual........
