I have been seeing some LEO's here with their cars parked on "official use only" overpasses used to cross busy highways, out of their cars. only catching quick glimpses i couldnt see if they were using lidar guns. my question is, if i have a third transponder plugged into the control unit of my LE30 (it's labeled R1 i do beleive), and that transponder receives a signal, do all three heads begin to jam? or just the rear one? also, would the same hold true that if the front heads are activated, does the rear one activate also?
