5) The RMR-C450 will hang from the bottom of the bracket and must have an
unobstructed view of the road ahead.
6) Insert the small end of the power cord gently into the power jack on the right
side of the unit and the large end into the cigarette lighter receptacle.
Remote mounting is not recommended.
Hard wire: Remove cigarette lighter plug. Connect the red wire to +12 Volts,
and then connect the white wire to ground. If your power cord has a dashed
white stripe then connect this white stripe wire to ground and solid black wire
to +12 Volts.
CONTROLS: There are 3 buttons on top of the RMR-C450: Dim, Mute and
City.
Dim: Press the Dim button for a split second (momentary contact) to dim the
alarm lights. There are 3 levels of illumination. To brighten the alarm lights
press the dim button again. The unit will have two beeps for “dim”, “dimmer”
and “dark”, and one beep for “bright”.
Mute: Press the Mute button for a split second (momentary contact) to disable
the alarm speaker for quiet operation. To reactivate the alarm speaker press
the Mute button again. The unit will have two beeps for “mute on” and one
beep for “mute off”.
Auto-Mute: Press the Mute button for a split second (momentary contact) to
disable the alarm speaker for quiet operation. In Auto-Mute operation it will
beep the signal 3 times then switch to mute automatically.
City: Engage the City function to reduce false alarms in high RF noise areas.
City function has 3 levels of sensitivity, City 1, City 2, and Highway mode.
Press the City button for a split second (momentary contact). With City 1 mode
“X” Band will be turned off and K – Ka sensitivity will remain 100% active. City
2 mode “X” Band will remain off and K – Ka sensitivity will reduce to 50%
sensitivity. Highway mode has all bands at 100% sensitivity. The unit will have
two beeps for “city 1”, three beeps for “city 2” and one beep for “highway”.
Selectable Tone: The RMR-C450 has selectable tones. To change the tone of
the unit, press and hold the Mute button down for an extended period of time
(approximately 3 to 5 seconds). A flat tone buzz changes the tone. Three
beeps returns the setting to normal.
Selectable VG2 alarm: To activate VG-2 detection, press and hold the City
button down for an extended period of time (approximately 3 to 5 seconds)
until unit beeps 3 times, VG2 is now on. VG-2 detection is now activated. To
deactivate press and hold the City button for an extended period of time
(approximately 3 to 5 seconds) until unit beeps a flat tone buzz. VG-2 is now
off. The unit will have three beeps for “VG2 on” and a flat tone buzz for “VG2
off”.
Voice On/Off: To turn the voice on and off press and hold the Dim button
down for an extended period of time (approximately 3 to 5 seconds) until the
unit responds, “voice on” or “voice off”.
Bi-lingual: To select bi-lingual mode from English to Spanish or Spanish to
English, power off the unit, press and hold the Dim button down while turning
power back on the unit.
Reminder! The C450 will memorize the settings of the features above
when the unit is powered off. Be sure to re-adjust the settings to your
normal preferences.
Test Function: To run the system diagnostics check on the unit press and
hold down both the Dim and City buttons simultaneously for an extended
period of time (approximately 3 to 5 seconds). The unit will perform a test
sequence to verify all systems are operating properly. Once the diagnostics
test is completed, the unit will remain with all LEDs lit. To reset the unit press
any button: Dim, Mute, or City. This test is also performed automatically when
the unit is powered on.
Power and Volume: Power is provided through the thumb wheel switch on the
left side of the unit. Rotate the wheel forward to turn on and increase the
volume for the alarm.
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 vehicle.
Alarms: A separate alert tone will sound for each band of Radar encountered
with a different colored light illuminated, (K/Ka-Green), (X-Red), (2, 3, 4-Red).
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 C450 is automatically undetectable by VG-
2/VG3.
Diagnostics: The RMR-C450 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.
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 ACTIVATION:
All scramblers are factory set to the OFF position.
Scrambler: To turn the scrambler on/off, power off 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.
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.
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 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 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 NOT legal in?
The Rocky Mountain Radar scramblers are not legal in Colorado, Utah,
California, Nebraska, Oklahoma, Minnesota, Illinois, Tennessee, South
Carolina (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. 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 –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.
