300 feet away - Answer 57
When adjusting radar range, you are shortening the length of the beam? - Answer False
Low setting - Answer Very close vehicles, strong signals
High setting - Answer Very far vehicles, weak signals
Can you mute the audio - Answer No
Brandis vs. Brown - Answer Everyone can testify to speed, common knowledge
Object brought closer to Radar - Answer Higher frequency than transmitted signal
Relative Motion - Answer Object stands still and RADAR moves
RADAR stands still and object moves
RADAR and object are moving in same direction at different speeds
When will RADAR show true speed? - Answer When the vehicle is going directly toward or
away from RADAR
Never set the RADAR any further than ____ degrees from direction of travel - Answer 20
