Frequently Asked Questions
The
Rocky
Mountain
Radar
model
RMR-8RDS
detector/scrambler is designed to give you radar and laser 
detecting and scrambling from the front and rear of the car. 
Can I test it with roadside trailer radars?
The trailers you see on the side of the road, that show your 
speed, are not legal to use to write tickets. They do not contain 
the sophisticated sampling computers that are in police radar 
guns. Since our units confuse the computer and there is none, 
they will not work reliably against the trailers. 
Can the police detect it?
The radar and laser scramblers do not have RF emissions and 
cannot be detected. 
What states are they legal in?
The Rocky Mountain Radar scramblers are not legal in 
Colorado, Utah, California, Nebraska, Oklahoma, Minnesota, 
Illinois (unless the scramblers are unplugged) and Virginia. 
The Rocky Mountain Radar detectors are not legal in 
commercial vehicles in most states. Use caution in these states.

What is Punch-Through?
The signal reflected by the car gets stronger the closer the target 
is to the radar gun. The Rocky Mountain Radar scrambler uses 
the radar signal as a carrier and reflects it through a high-gain 
antenna. It will work only as long as the scrambling signal is 
greater than the signal from the target. Punch-through is when 
these signals are equal or within 50-200 feet. 
What is the effective range?
The radar scrambler works at four to six times the range of the 
radar gun. The laser scrambler is effective at more than two 
times the Lidar range. 
 
Important information:
When driving in states that ban scramblers – unplug 
the front and rear scramblers. Detectors are legal in all 
states except Virginia and Washington D.C. With the 
scrambler off, this unit is only a detector.
