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.
• How do I know the scrambler is working?
When you turn the unit on and it goes through the
self-test (a series of tones), to confirm all the circuits
in the scrambler are working correctly.
• Why won’t my unit turn on?
Check the following:
1) The on/off thumbwheel on the side of the
unit
2) The fuse in the power cord. (To check
the fuse in the power cord, unscrew the
silver tip end that plugs into the cigarette
lighter. If the fuse is blown, replace with
a 2 amp fast burning fuse).
3) The fuse for your cigarette lighter
4) If it is none of these, return the unit to
the manufacturer for repair/replace at our
discretion.
