band of Radar encountered with a different colored
light illuminated, (K/Ka-Green), (X-Red), (2, 3, 4­Red). The signal strength indicators are the numbers
2, 3 and 4, the stronger the signal the more numbers
indicated will light up. Tone frequency will increase
as signal strength becomes stronger. All alarm lights
(X, K/Ka, 2, 3, 4) will flash when Laser is detected.

Signal Strength: Signal Strength will be first
indicated by the illumination of the LED of the band
detected, then the three numbers 2, 3, and 4 red
LED’s. When all three are illuminated the signal is
strongest.

VG-2: VG-2 detection is indicated with a separate
alarm along with the yellow power light (P)
blinking.

The C435 is always undetectable by VG-2/VG3.
Diagnostics: The RMR-C435 has a full internal

automatic diagnostic system. If the power light goes
off and remains off, check the 2-amp fuse in the

power cord by unscrewing the silver tip and
removing the fuse. If the fuse is good (wire inside
the fuse unbroken), return the unit for service.

SPECIFICATIONS:
Radar Scrambler:

Frequencies: 8.0-38.2 GHz

Antenna: Dual ridge cast waveguide

Mixer: Custom MM wave Schottky

Doppler: Pseudo Random Digital Noise Generator

Lidar Scrambler:

Full laser coverage using asynchronous pulse
position modulation to confuse the lidar computer.

How does it work?

The Rocky Mountain Radar scramblers are full­featured radar and laser scramblers combining active
laser and passive radar scrambling capabilities.
The radar scrambling circuit mixes Pseudo Random
Digital Noise Generator (PRDNS) with the
incoming police radar signal and reflects it back to
the radar gun. The computer in the radar gun must
receive eight identical, consecutive readings before
it will display your speed. All the different speeds

contained in the White Noise confuse the computer
in the radar gun so it does not display any speed.
This effect duplicates the normal operation that the
officer often sees.
Since it is normal to occasionally lose the target
speed, the officer is not suspicious. Reasonable care
should be used as flagrant violators could still be
caught with an estimated speed.
The laser scrambling circuit transmits a series of
pulses at the same wavelength used by the police
laser guns (Lidar), which are electronically timed at
about 100 feet apart. When the pulses pass through
the windshield they will lose up to 50% of their
power. The power output is 6 to 10 times that
needed to trigger the detector in the laser gun. Lidar
sends out laser pulses and measures how long it
takes to hit your car and come back. From the speed
of light it can determine your range. It sends out
several more pulses and calculates your speed from
the change in distance over time. The Rocky
Mountain Radar scramblers only allow the Lidar to
see up to 100 feet so it is unable to calculate your
speed.

the unit, press and hold the City button down while
turning power back on the unit.

If the scrambler is on, the “T” LED light will be

included in the start up sequence. If the scrambler is

off, the “T” LED light will not be included in the
start up sequence. The “T” LED light is the test

diagnostics for the scrambler.

SCRAMBLER OPERATION:

Drive normally. When the detector sounds an alert,
take your foot off the gas, check your speed, adjust
if necessary, and resume driving. Do not apply
brakes unless you are grossly exceeding the speed
limit. The scrambler will disable the radar long
enough for you to adjust speed safely, if necessary.

Important information:
When driving in states that ban scramblers –
turn off the scrambler function. Detectors are
legal in all states except Virginia and Washington
D.C. With the scrambler off, this unit is only a
detector.

IS IT LEGAL?

The Rocky Mountain Radar scramblers conform to
all FCC rules and regulations. Part 15 of the FCC
code regulates consumer products that may leak or
transmit radio frequency energy into the atmosphere.
Since the scramblers are not transmitters, these
sections do not apply.
The radar scrambler is a reflective receiver and has
no emissions. It does not transmit, but uses the

police radar gun’s own signal as a carrier of its

information. The laser scrambler transmits a series
of light pulses. There are no laws regarding the
transmission of invisible light.

Rocky Mountain Radar does not condone the use
of excessive speed on the highways, nor does it
endorse breaking the speed limit laws of the
United States of America. Please drive safely
when using this or any other electronic product
in your car.

FREQUENTLY ASKED QUESTIONS

The Rocky Mountain Radar scramblers are
designed to give you radar and laser scrambling
from the front half 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 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 NOT legal in?

The Rocky Mountain Radar scramblers are not legal
in Colorado, Utah, California, Nebraska, Oklahoma,
Minnesota, Illinois, Tennessee, South Carolina

8

(unless the switchable scrambler feature is set to
off) 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. Punch­through is when these signals are equal or within 50­200 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.

• Where is the best place to mount my unit?

The manufacturer recommends in the upper center
of the windshield (right below the rear-view mirror)
for the maximum coverage. There can be no metallic
interference with the unit.
