Page 19: Speed Monitoring
SPEED MONITORING Radar Facts A radar gun operates by transmitting radio waves at certain frequencies which reflect off objects and are then picked up by the radar gun’s receiving section. When a radar beam reflects off a moving target, a measurable frequency shift occurs. - Page 20 Laser Facts (Continued) • Because the vehicle’s license plate or headlights are the laser gun’s primary targets, mounting the Whistler detector on the dashboard can improve laser detection at short range. • Do not follow closely behind any vehicle. If you can’t see past a vehicle ahead of you, chances...

Questions and answers
Recently my CR73 works fine but it's default display is N 0 C I know what C is (City), but what is N? Is this "North," and is there some sort of initial set-up by which I "tune" the detector with the position of my car (N,S,E,W)? If so, how do I do this?
My CR73 has a letter N on the left side of the display. What does this mean; the unit works well in all other respects. Is the N supposed to mean NORTH, and is this some sort of set-up mode with N S E W directions? If so, what are the instructions?
