Front Antenna
It is very important that the front antenna is mounted properly.
Determine the best location for the front antenna. The optimal
location for mounting the front antenna depends on the
vehicle’s type. In most vehicles the best mounting location is
directly behind the grill through the slot openings. It should
have a clear view of the road ahead. Other locations that
provide concealment and/or protection of the antenna may be
acceptable.
Using the supplied mounting bracket, mark location and drill
pilot holes in the vehicle if necessary.
Fit the mounting bracket using the washer screws.
Verify the lens of the front antenna has a clear view of the road
ahead.
You can use the included Dual Lock tape to attach the mounting
bracket. Thoroughly clean any surface before the tape is
applied.
Front Scrambler
It is very important that the scrambler is mounted properly. The
scrambler scrambles the radar and laser signals received from
the front and detect laser signals.
Determine the best location for the scrambler. For optimum
performance, install the scrambler on either side of the front
license plate on the bumper or in the front grill area.
Using the built in mounting bracket, mark location and drill
pilot holes in the vehicle if necessary. 3
NOTE:
DO NOT drill holes in the front antenna or scrambler modules.

Thoroughly investigate the location before drilling any holes.
Keep all cables away from moving parts and hot surfaces
(Radiator, hoses, engine, etc.)
Make certain that the modules are level and have a clear view of
the road ahead.
Rear Scrambler
The rear scrambler detects and scrambles the laser signals
received from the rear and scrambles all radar.
Determine the best location for the rear scrambler. For optimum
performance, install the rear scrambler on either side of the rear
license plate or above third brake light on the rear deck.
Control Module
Determine the best location for the control module in the
vehicles interior.

CARE AND MAINTENANCE
Your RMR-8RDS remote is an example of superior design and
craftsmanship. The following suggestions will help you care for
your remote so you can enjoy it for years.
Never leave your Control Module on the dashboard when your
vehicle is left parked for an extended period of time. The
temperature in the vehicle during the summer can reach levels
above what is considered safe for the Control Module.
To make you less susceptible to break ins and theft, do not leave
the Control Module in a visible location when leaving your
vehicle unattended.

Try to avoid road splash or other liquids that can damage the
internal components and reduce the performance of the detector.
Periodically check and wipe off any dirt from the front antenna
and scrambler modules. Use a soft cloth to avoid scratching the
lens.
TROUBLESHOOTING
If the Control Module does not turn on:
Check the power cord. Be sure all power connectors are
properly installed and pushed in all the way.
Check the fuse in the power cord that goes to the cigarette
lighter socket.
The cigarette lighter socket may be dirty. Clean it with a soft
cloth to ensure a good clean connection.
There may be a problem with the vehicles electrical system.
Be sure to fully press the Power button.
CAUTION: Do not place any metal objects other than the
cigarette lighter or a cigarette lighter plug in the cigarette lighter
socket. Doing so could blow a fuse in your vehicle or cause the
metal object to become very hot.
If the remote gives false alerts when the vehicle hits bumps:
Check the vehicle’s electrical system including main battery
cable and alternator connections.
Install a filter capacitor (470uf, 35 volts) on the back of the
cigarette lighter socket across the power connection.
Verify that the front antenna and scrambler modules are not
obstructed.
Relocate the front antenna and both scrambler modules to a
clear view of the road.
Verify the cables are correctly connected to the Control Module.
FUSE REPLACEMENT
The lighter socket adapter of the power cord has a replacement
2 amp SAG fuse located below the silver tip. To check or
replace the fuse, slowly and carefully unscrew the tip of the
plug. Make sure the spring and silver tip located inside the plug
do not fly out when you remove the cap. Check fuse and replace
if necessary. 9

How does it work?
The Rocky Mountain Radar scramblers are full-featured radar
and laser scramblers combining active laser and passive radar
scrambling capabilities.

The radar scrambling circuit mixes a Doppler FM chirp 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 FM chirp confuse the
computer in the radar gun so it does not display any speed. This
effect duplicates the normal operation that the officer usually
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 four to eight 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.
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.
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.
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. 11
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.

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.
12
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.
