INSTALLATION IS THE KEY TO PERFORMANCE
S DSR 2X consists of a dash-mounted display unit; a counting unit that can be mounted with the display unit, or separately
using the optional Remote Cabling Kit (P.N. 200-0247-00); one or two antenna units; and a wireless or wired remote control unit.
S
component should be installed in a location that provides good operator visibility and convenience, but does not obscure the road or
interfere with air bag operation. The Ka-band antenna units are fully waterproof and can be installed outside the vehicle, if desired.
The display and counting units are not
available from the factory for specific installations, if needed.
Display/Counting Unit - To mount the combined display/counting units, connect the Power Cable to the 9-pin connector on the
back of the counting unit. Plug the front and rear antenna cables into their respective connectors on the back of the counting unit.
After attaching the mounting bracket to the selected mounting surface with Velcro or screws, insert the combined display/counting
unit into the mount and secure with thumbscrews (provided) into the threaded holes located on each side of the counting
Display Unit - To mount the display unit only, separate the counting unit from the display unit by unscrewing the two screws on the
back panel. Connect the 15-pin cable, supplied in the Remote Cabling Kit, to the connector on the back of the display unit. Attach the
display unit to the mounting bracket using one thumbscrew on each side or attach directly to the dash. After mounting, make sure the
display will not dislodge during high-speed maneuvers.
Counting Unit - To mount the counting unit separately from the display unit, select an out-of-the-way mounting location, such as
under the dash or under the front seat. Connect the Power Cable to the power jack located on the back of the counting unit. Plug the
front and rear antenna cables into the back of the counting unit. Connect the 15-pin cable, supplied in the Remote Cabling Kit, to the
connector on the front of the counting unit. Secure the mounting bracket on the counting unit to a suitable mounting surface with
Velcro or screws. Install the counting unit into the bracket using a star knob on each side.
Antenna Unit - Before proceeding with the final installation, check the intended mounting locations for fan interference on both
antennas. See the section on fan interference, page 3. Find a suitable location and attach the antenna mounting bracket to the selected
mounting surface. Attach the antenna unit to the bracket. Connect the antenna cable to the antenna. Repeat these steps for the second
antenna.
Ergonomic Remote Control - The only installation required for the ergonomic remote control (P.N. 200-0579-00 Fast-Lock
model; 200-0579-01 Instant-On model) is to install the 3V 123 battery. Remove the battery compartment cover by pressing down on
the battery cover latch and rotating the battery cover away from the case. Install the battery, paying attention to the polarity markings.
Replace the battery cover until it snaps in place. Velcro may be applied to the back of the remote control unit to attach it to the dash or
other locations. Also, a microphone lug (supplied) can be attached to the back of the ergonomic remote control to allow installation
into a microphone holder. An optional lanyard is also available.
Wired Remote Control Cable - The Remote Control can be operated in wired mode by connecting a standard RJ-11 modular
telephone handset cord (P.N. 155-2213-00 or Radio Shack #279-312). The cord is connected to the remote and radar unit, and battery
removed for wired operation.
DSR 2X is powered from the 12-volt, vehicle power system using a Power Cable from the counting unit. Each system

AVOIDING FAN NOISE
As you will discover, the S DSR 2X that you have purchased is extremely sensitive resulting in longer range. If care is not
taken when installing the radar in the vehicle, this extra sensitivity may allow you to pick up Fan Noise when operating the radar from
inside the patrol vehicle. Fan Noise can result in erroneous high-speed readings when operating in Same Lane mode – particularly
with Same Lane Faster mode enabled.
Fan Noise Is Common
Fan Noise is a common Doppler radar problem when aiming the antenna through a window from inside the patrol vehicle. Doppler
radar is designed to detect moving or vibrating objects. A small amount of the radar beam is reflected from the glass back into the
vehicle. This beam reflection may allow the radar to “see” the vibrating defroster vents or the vehicle dash that is vibrating as a result
of the fan blower motor. If the antenna is mounted close to the top surface of the vehicle dash, the radar beam can “see” a portion of
the vehicle dash that is vibrating. We recommend mounting the front antenna as high on the glass windshield as is feasible. Higher
mounting will also result in better patrol speed tracking and longer operational range. Fan Noise can be verified by turning off or
changing the speed of the fan.
Most fans generate speeds of 30 mph or less. As a result, Fan Noise is normally a problem when operating in Stationary mode or
when operating in Moving mode with patrol speeds less than 30 mph or operating in Same Lane mode (particularly Same Lane Faster
mode).
Opposite Lane operation: since opposite lane radar only sees Doppler signals above the patrol speed, Fan Noise will not affect an
opposite lane radar operating at patrol speeds above about 15 mph.
Stationary operation: a radar operating in Stationary mode will see Doppler signals from 5 mph to 200 mph. Clearly, a Fan Noise
signal between 5 mph and 30 mph will be seen and result in false readings.
Same Lane operation: a same lane radar adds or subtracts the difference speed (patrol vehicle - target vehicle) to obtain the absolute
target speed. This difference speed is commonly between 5 mph and 30 mph. Clearly, a Fan Noise signal between 5 mph and 30 mph
will be seen and result in false readings.
ALERT: It is critical that you eliminate Fan Noise false readings for the S DSR 2X if you
use the factory defaults with Same Lane Faster mode enabled.
How to check for Fan noise:
1. Operate the S DSR 2X in XMIT mode, Opposite/Same Stationary, and SEn 4.
2. Turn your vehicle fan motor to the “highest” speed.
3. Locate your stationary vehicle so that the radar beam is clear of moving objects or large reflective objects.
4. Fan Noise can be verified by turning off or changing the speed of the fan.
5. Verify that no speed readings are observed – realize that moving trees or grass can result in speed readings corresponding to
the speed of the wind.
6. Move the antenna (as required) until a location is found that results in no Fan Noise readings above about 4 mph – a high
corner of the windshield is usually best.
7. As a last resort, mount the antenna completely outside the vehicle.
8. If a rear antenna is used, repeat the testing for this antenna.
To Eliminate Fan Noise, try the following steps in numerical order:
1. Find a location (by moving the antenna) inside the vehicle that is free of Fan Noise; such as the upper left corner of the
windshield.
2. Ensure that the antenna beam is not deflected back into the vehicle by anything in its path such as wipers, window trim, or
anything mounted on the dash. Do not mount the counting/display unit or antenna/power cables in front of the antenna on the
dash.
3. Locate the antenna as close to the glass surface as possible (preferably less than 1/2 inch).
4. Turn the fan off
mode – especially with Same Lane Faster mode enabled.
5. As a last resort, turn Same Lane sensitivity from 4 down to 3 ( SEn 3) or mount the antenna completely outside the vehicle.

HOW TRAFFIC RADAR WORKS
Stationary Mode - All traffic radar uses the Doppler frequency shift technique to measure the speed of moving vehicles. This
technique is based on the Doppler Principle, which states that a radar signal reflected from a moving target will experience a
frequency shift that is proportional to the speed of the target relative to the radar. Circuitry in the traffic radar then processes the
reflected signal to obtain the frequency shift and translate this frequency shift to speed.
In stationary mode, the transmitted signal strikes a moving target and is reflected back to the antenna. The traffic radar then measures
the frequency shift to obtain the target speed.
Prior to the introduction of the S
In conventional traffic radar, targets both closing and moving away generate the same Doppler frequency shift, and it is not possible to
distinguish their direction. Since the conventional radar cannot distinguish the direction of the targets in its beam (closing or away)
the operator had to rely on visual observation to determine target direction.
Now, the S
DSR 2X has the ability to filter out Doppler signals based on their direction. For example, while monitoring front
closing targets, the 2X can reject Doppler signals from all front away targets.
S
DSR line is the first practical radar to use a dual-channel antenna design. Each antenna actually has two sets of microwave
circuits and two sets of amplification/digitizing circuits. The two microwave circuits are designed to provide two simultaneous
Doppler signals with a 90° phase difference depending on direction.
Both channels of digitized Doppler information are sent to the DSP (Digital Signal Processor) circuit in the counting unit. The highspeed DSP circuit then performs a Complex Fast Fourier Transform
direction for each target.
Opposite Lane Moving Mode - In opposite lane moving mode, two (2) signals must be processed to determine target speed.
The first signal, patrol speed, results from the radar signal reflecting from the roadway ahead of the radar. Since the Doppler shift is
proportional to the relative velocity between the radar and the roadway, the Doppler shift of this signal will be proportional to the
speed of the patrol vehicle. The second signal, closing speed, results from the radar signal reflecting from an approaching or retreating
opposite lane moving target back to the patrol vehicle. The Doppler shift of this signal will be proportional to the sum of the patrol
speed and target speed, or closing speed. To determine the target speed, S

computation simultaneously on each channel to obtain relative
DSR 2X subtracts the patrol speed from the closing
Same Lane Moving Mode - In same lane moving mode, two (2) signals must be processed to determine target speed. The first
signal, patrol speed, results from the radar signal reflecting from the roadway ahead of the radar. Since the Doppler shift is
proportional to the relative velocity between the radar and the roadway, the Doppler shift of this signal will be proportional to the
speed of the patrol vehicle.
The second signal, the difference speed, results from the radar signal reflecting from an approaching or retreating same lane moving
target back to the patrol vehicle. The Doppler shift of this signal will be proportional to the difference speed between the patrol and
target vehicles. If the target vehicle is moving faster than the patrol vehicle, the difference speed will be added to patrol speed to
obtain target speed. If the target vehicle is moving slower than the patrol vehicle, the difference speed will be subtracted from the
patrol speed to obtain target speed. To reduce user confusion, front same-lane targets and rear same-lane target will be rendered by
the S
DSR 2X using two different Doppler tones. Front same-lane targets will use the same Doppler tones as used for
opposite-lane targets and stationary targets. Rear same-lane targets will use a lower tone that is proportional to the difference Doppler
shift between the patrol vehicle and the target.

The addition of the fast mode allows the ability to track small high speed targets that normally could not be tracked because a stronger
target shields the weaker target from normal speed measurement. The classic example is where a speeding sports car passes a slower

REAR TRAFFIC ALERT
Rear Traffic Alert, a proprietary new feature of the S DSR 2X, is designed to warn the patrol officer of rapidly overtaking rear
same-lane traffic. Rear Traffic Alert is active when the patrol vehicle is most vulnerable to rear-end collisions - pulling into traffic
from a standing start. If the S
approach speed, it prompts the officer with a distinctive “English Horn” audio sound and flashes ALE rt in the rear antenna speed
windows.
Rear Traffic Alert can be disabled in the OPTIONS MENU (See page 46). Please contact Applied Concepts, Inc. at 1-800-S
or your Factory Sales Representative. Rear Traffic Alert can also be disabled by setting the closing speed to a high speed such as 200.
Rear Traffic Alert is always active (unless disabled in the OPTIONS MENU – see page 46). Rear Traffic Alert is independent of the
rear target zone selection – either the Rear Opposite or Rear Same target zone can be selected. In a traffic alert condition, the 2X will
sound the alert tone and flash the alert display as long as the threat persists. Once the threat is gone, the 2X will automatically resume
tracking the rear targets. Rear Traffic Alert will be disabled if the rear antenna is placed in HLd (hold).
With Rear Traffic Alert enabled, go to the OPERATOR MENU (See page 6) to select the Rear Traffic Alert closing speed. In the
OPERATOR MENU, repeatedly press the MENU key until ALE rt is displayed. Set the desired Rear Traffic Alert speed by using the
Ï and Ð keys (the factory default speed is 30 mph). Pressing the Ï key or the Ð key will initially change the number count slowly,
but after about 1 second, the counting will speed up. Exit the OPERATOR MENU mode and return to radar mode by pressing any of
the four zone keys.
Rear Traffic Alert Requirements:
1. The radar must have VSS cabling installed in the vehicle and must be operating in VSS mode.
2. The rear antenna must be transmitting with either the Rear Opposite target zone or the Rear Same target zone selected.
DSR 2X senses a rear approaching vehicle closing at a speed in excess of the user adjustable
3. Direction sensing will be used to ensure that the rear traffic is closing on the patrol vehicle.
4. The radar sensitivity is reduced to less than SEn 1 (to ensure close proximity) for measurement of approaching rear traffic.
All rear targets that are “outside” of the Rear Traffic Alert requirements will have normal sensitivity.
5. To reduce Rear Traffic Alert warnings while traveling at a steady speed, slowing down to turn, or slowing down to a stop, the
radar only enables Rear Traffic Alert when it senses vehicle acceleration.

connected to the remote and
radar unit, and battery removed
for wired operation.
Remote Control Keys:
Several of the keys have dual functions. An underlined word on a key indicates that the key must
be held down until two beeps are heard for that function to operate. All keys with underlined
words operate with a delay time and will beep two times. The first beep occurs when the key is
initially pressed and the second beep occurs when the key actuation delay time expires.
MOV/STA: The MOV/STA key toggles between moving and stationary modes. A speed or a [ ] in the patrol
window indicates moving mode, while a blank patrol window indicates stationary mode. With a
VSS cable installed, the radar will automatically switch between moving and stationary modes
based on the presence (or absence) of VSS pulses and [ ] will not be seen in the patrol window.
(See page 39 for more information on VSS.)
After selecting moving mode or stationary mode, the operator can use the four zone keys
(described below) to select the Target Zones to monitor targets on the front antenna and the rear
antenna simultaneously. The SAME and OPP icons display the zone selection in both moving
and stationary modes. Each antenna is totally independent of the other relative to Target Zone
selection. The stationary modes (and associated icons) for the front antenna are: stationary closing
(OPP), stationary away (SAME), and stationary bi-directional (OPP/SAME). The stationary
modes for the rear antenna are: stationary closing (SAME), stationary away (OPP), and stationary
bi-directional (OPP/SAME).

THE HOW AND WHY OF PATROL SPEED SHADOWING
Traditional radar units exclude patrol speed tracking below 20 mph. One of the unique features of S DSR 2X is that it allows
patrol speed tracking below 5 mph, when the low-end patrol speed is set to 5. This feature is very popular and is excellent for
enforcing school zones. However, with this setting, S
strong same lane target in the radar beam captures the patrol speed, instead of the weaker passing ground reflection.
The following is an example of the shadowing effect: A patrol vehicle traveling 30 mph is following a pickup traveling
42 mph. The pickup is pulling away from the patrol vehicle at 12 mph. The radar, in error, thinks this 12 mph speed is the correct
ground speed and displays 12 mph in the patrol window, instead of the correct value of 30 mph.
DSR 2X is more prone to "shadowing." Shadowing occurs when a
S
pressing the PS BLANK key, 2) change the low-end patrol speed from 5 mph to 20 mph (see Page 22 for instructions), 3) operate the
radar using the optional VSS mode. To eliminate the shadowing effect in the city, Option 1 is recommended. Option 2 is
recommended for highway radar use. Option 3 eliminates all shadowing and is achieved by installation of VSS cabling in the patrol
vehicle.
DSR 2X has three options for eliminating the shadowing effect: 1) make the unit re-acquire the correct patrol speed by
USING THE STOPWATCH MODE
S DSR 2X offers Stopwatch mode, which can be disabled or enabled through the Options Menu (See Page 46). Stopwatch
mode is used to measure target speeds using the traditional time-distance method. All of the timing and computing is performed in the
S
using the remote control Ï or Ð keys. The maximum length of the measurement zone is 9999 feet or 9999 meters.
Since the electronic timer is started (by pressing START/STOP) when the target vehicle enters the measurement zone and stopped
(by pressing START/STOP again) when the target vehicle exits the measurement zone, the time to traverse the measurement zone is
measured and displayed on the counting unit. After the completion of each start/stop timing interval, the counting unit displays the
calculated target speed in the patrol window.
NOTE: IT IS REQUIRED THAT THE FRONT ANTENNA BE CONNECTED DURING STOPWATCH MODE. THE
COUNTING UNIT USES THE ANTENNA INTERNAL CRYSTAL FOR START/STOP TIMING DURING STOPWATCH
MODE.
Stopwatch Principle
The counting unit calculates speed by measuring how much time it takes the vehicle to pass through the pre-set distance and then
calculates and displays the speed in MPH or KPH. The known distance is divided by the measured time and multiplied by a
conversion factor to obtain target speed.
DSR 2X counting unit. The length (in feet or meters) of the measurement zone must first be entered into the counting unit
Example: 1/2 mile (2640 feet) of distance over 30 seconds of time = 60 mph
1/4 mile (1320 feet) of distance over 15 seconds of time = 60 mph
1/4 mile (1320 feet) of distance over 11.9 seconds of time = 75 mph
The speed (mph) formula is: mph = 0.682 x Distance (in feet)
Time (in seconds)
To easily convert feet/sec into mph, there is a 0.682 conversion factor that is used. Multiplying feet/sec by the 0.682 conversion factor
will provide speed in miles per hour.
No hard and fast rule can be established concerning the minimum distance over which a vehicle should be monitored. However,
several factors enter into the equation which does establish the fact, that the farther the distance, the less the chance of impact of an
error. Three factors that can influence the calculation include:
1. Human error in activating the START/STOP key
2. The distance measured
3. The speed of the vehicle
28
Page 33
Human error can occur by the operator not pressing the START/STOP key at the precise time that the vehicle enters and exits the
measurement zone.
If too short of distance is entered, it increases the chance for error. We recommend a minimum of 660 feet.
The greater the speed, the longer the measurement distance should be to reduce the possibility of an error. For example, if you are
mostly measuring high speeds you should measure using a longer distance than if measuring slow speeds.

Stopwatch Mode Errors
If you get an Err message (Fig. 34) while trying to operate in Stopwatch
mode, verify that the front antenna is properly connected and functioning.
The counting unit uses the front antenna’s internal crystal for start/stop timing
during Stopwatch mode. At the end of each timing interval the front
antenna’s internal crystal is compared against the counting unit crystal within
a small tolerance. If a crystal error is detected, the Err message is displayed.

HOW FASTER SPEED TRACKING HELPS THE PATROL OFFICER
Faster Speed Tracking can be enabled or disabled through the Operator Menu (see page 6) or through the Options Menu (see page 46).
The following examples are Faster targets under various conditions. In addition to the speeds displayed in each window, carefully
note the icons illuminated.
Faster mode allows S
DSR 2X to track a smaller high-speed target that was previously undetectable because a stronger target
shielded the weaker (smaller) target from normal (strongest target) speed measurement. The classic example is where a speeding
sports car passes a slower moving eighteen wheeler. The Faster sports car, although clearly speeding, could not be measured because
the strongest truck target captured the target display window. S
DSR 2X with Faster capability, however, will display the
speed of the strongest target (the truck) in the target window, while the speed of the Faster target (the sports car) will appear in the
middle Faster window.
S
Faster window is reserved for the Faster
DSR 2X simultaneously tracks both targets: however, the target window is always reserved for the strongest target and the
target. When the Faster target becomes the strongest target, the Faster target’s speed will
transfer to the strongest target window. Either the strong target or the Faster target’s speed can be locked. See the examples below:

INTERFERENCE SOURCES AND REMEDIES
A variety of sources, both natural and man-made, can cause misleading indications or poor performance. The operator should note the
symptoms described below, and take steps to avoid the problem, or ignore the misleading indications.
Terrain
Radar signals will not pass through most solid objects, including tree foliage. Make certain the path between the radar and target
vehicle is unobstructed. A glass window is a partial reflector of radar. Therefore, some reduction in range will be experienced when
aiming through patrol vehicle windows.

Rain absorbs and scatters the radar signal. This reduces the range and increases the possibility of obtaining readings from the speed of
the raindrops.
Electrical Noise
Electrical noise sources include neon signs, radio transmitters, power lines, and transformers. These influences may cause reduced
range or intermittent readings. When these interferences are present, the RFI indicator should come on and suppress all readings.
Vehicle Ignition Noise
An extremely noisy vehicle electrical system may cause erratic operation. If this condition occurs, it is recommended that a two
conductor shielded (fused) cable be run directly from the vehicle battery to the cigarette lighter plug on the dash. This should
eliminate any problems from vehicle electrical noise.

Interference From Other Transmitters
Strong signals from nearby radio transmitters may interfere with
operation of S
that an interference source has been detected (Fig. 38). Speed
readings are inhibited when this occurs to prevent the possibility of
false readings. The interference source may be the vehicle’s twoway radio, another nearby transmitter, or an illegal radar-jamming
device.

Low Supply Voltage
A low voltage condition from the vehicle’s electrical system will
cause the U Lo display to illuminate (Fig. 39), and will inhibit speed
readings. An extremely noisy vehicle electrical system may result in
false readings or erratic operation. If this condition occurs, a twoconductor, shielded (fused) cable should be connected directly from
the vehicle battery to the cigarette-plug on the dash. This should
eliminate any problems from vehicle electrical noise.

Power-On Self-Test
Each time the unit is powered on, an automatic self-test is performed
to verify that the unit functions. All displays indicate 888 (Fig. 40)
during the test. A 4-beep “happy” tone indicates the successful
completion of this test. If a problem is detected, FAIL will be
displayed along with a 20-beep tone. Immediately after power-on,
and while all display segments are illuminated, pressing the MENU
key will display the software version followed by the nominal

A directional moving vehicle test can be performed as an additional check of performance and accuracy. To perform the moving
vehicle test: press the PWR key to turn on the radar. Use the MOV/STA key to switch into Stationary mode. (Note: This test cannot
be performed with VSS activated.)
TO TEST THE FRONT ANTENNA:
While driving a patrol vehicle, with an accurately calibrated speedometer, aim the front antenna down an empty highway directly in
front of the vehicle. While driving forward, alternately switch between the front OPP target zone and the front SAME target zone.
As you alternate between the two target zones, verify that the front OPP target zone always shows an accurate ground speed in the
target window while the front SAME target zone always shows no speed in the target window. While in front OPP target zone, the
moving roadway appears as an approaching target to the radar and will be seen in the front target window but will not be seen when
the radar is in the stationary front SAME target zone.
TO TEST THE REAR ANTENNA:
While driving a patrol vehicle, with an accurately calibrated speedometer, aim the rear antenna down an empty highway out the rear
window of the vehicle. While driving forward, alternately switch between the rear OPP target zone and the rear SAME target zone.
As you alternate between the two target zones, verify that the rear OPP target zone always shows an accurate ground speed in the
target window while the rear SAME target zone always shows no speed in the target window. While in rear OPP target zone, the
moving roadway appears as a receding target to the radar and will be seen in the target window but will not be seen when the radar is

THE PERFECT PATROL SPEED WITH VSS
Traffic Radar Patrol Speed Measurement
Moving traffic radar systems normally obtain patrol speed by measuring the speed of the radar return from the moving roadway in
front of the moving vehicle. Patrol speed tracking sometimes suffers from anomalies known as “batching” and “shadowing.” These
anomalies occur during moments when the roadway is obstructed from the radar beam by road conditions or other vehicles. The
solution is to allow the traffic radar to monitor vehicle tire rotation and to use this information to perform “patrol speed steering.”
There are two ways to monitor tire rotation. One way is through the CAN Bus using Stalker’s exclusive CAN/VSS Adapter; the other
is to attach directly to the Vehicle Speed Sensor (VSS) signal in the patrol vehicle.
The CAN/VSS Solution – VSS Advantages without VSS installation problems.
You can skip VSS installation when you use Stalker’s CAN/VSS Adapter to power your Stalker radar in the patrol vehicle. Unlike
connecting to the vehicle’s VSS, which can be a challenge to locate, the OBDII diagnostic connector is easy to find and takes only
seconds to connect.
Locate your vehicle’s OBDII connector. Connect the Stalker CAN/VSS cable.
The CAN/VSS Adapter is Stalker’s preferred method for automating the radar’s patrol speed acquisition as well as transitioning back
and forth between stationary to moving modes.
The VSS Speedometer Signal
All modern vehicles have a VSS sensor (Vehicle Speed Sensor) attached to the transmission or an axle that generates a speed signal.
The speedometer and other electronics in the vehicle use the VSS speed signal. By tapping into this signal, the Stalker DSR 2X can
monitor the actual patrol car speed and use the VSS speed information to help the radar pick the correct ground speed. The radar’s
patrol car speed is still always measured by radar. The VSS simply helps steer the radar into making the right choice.
VSS Cable Installation
To take advantage of VSS patrol speed steering,
requires two cables that are provided with the VSS
Option (VSS Installation Kit PN 200-0622-00).
The vehicle VSS cable (PN 155-2221-00), should be
permanently installed by an automobile service shop
using the included installation instructions.
On the right is how the vehicle VSS cable is normally
attached (with 3 screws) to the bottom of the dash with
a metal L-bracket for convenience.
The radar VSS cable (PN 155-2178-00) replaces the
conventional cigarette power cable and can be removed
from the vehicle with the radar.
IMPORTANT NOTE: Observe the black polarity marks on the two white 6-pin VSS connectors that plug together. The two white 6pin VSS connectors can be plugged together with the marks in alignment or the marks opposed. Because of vehicle VSS signal level
variations, one of these plug-in positions may not provide a working VSS signal to the radar. If you observe the symptom of the
speedometer not functioning or the symptom of the radar not “seeing” the VSS signal, rotate the marks 180° and try again.
39
Page 44
Either Way, the Result is PERFECT Patrol Speed
• The radar will never shadow.
• The radar will never batch.
• It tracks and acquires patrol speeds from 1-200 mph.
• Moving / Stationary selection becomes automatic.
• Patrol speed variations produced by weather effects are greatly reduced.
• Patrol speed variations produced by road clutter cosine effects are greatly reduced.
• Low speed combing effects are eliminated.
AUTOMATIC VSS CALIBRATION
Once the VSS cables are properly installed, the radar is ready to synchronize the vehicle’s VSS signal with the radar’s ground speed
readings. The calibration sequence will determine the proper ratio between the VSS signal speed and the radar ground speed. The
numeric result is stored in the radar’s memory (called a calibration factor).
Every time the radar is turned on and then operated, the auto-calibration routine is triggered. The very first time the radar is installed
and operated, the auto-calibration sequence may take a few minutes (since there is not a previously stored calibration factor to verify).
During successive operations, in the same vehicle, the auto-calibration routine will seem instant.
First Time Calibration (or Installing the Radar in a New Vehicle)
To auto-calibrate you will need to operate (with the radar transmitting) in the moving mode for a few city blocks. The radar can
complete the calibration sequence much faster if the speed of the vehicle is varied above 20 mph (don’t merely drive at a steady speed
at first). When you see the patrol speed window consistently showing an accurate speed, then the auto-calibration sequence has been
successful. If, after several blocks of driving, the patrol speed display is either blank or incorrect, then unplug the 6 pin VSS cable
connector, rotate it 180 degrees, power up the radar, and try again.
Automatic Moving / Stationary Selection
When the radar is receiving VSS signals, and it has been calibrated, the unit should automatically switch between moving and
stationary operation modes when the patrol vehicle moves and stops. While moving, the Radar Mode key will not override the
moving / stationary mode selected by the VSS steered radar. (Note: During the 5-minute tuning fork test the VSS is deactivated to
allow manual switching from stationary to moving mode.)
Low Speed Speedometer Problems
In some vehicles, the VSS signal is non-existent at speeds below 5-10 mph so you may see no change in the car’s speedometer reading
until the car exceeds 10 mph. In these cases, the Stalker DSR radar will also not be switched into moving mode until the patrol car
exceeds 10 mph.
Tuning Fork Tests with VSS
With VSS activated, the radar must be in the TEST mode prior to manually selecting moving mode.
NOTE: During the 5-minute tuning fork test, the VSS is deactivated to allow manual switching from stationary to moving mode.
Patrol Speed Low Cutoff
The 5th Menu option (see page 6) is Patrol Speed Low Cutoff or Lo5, Lo 20. Patrol 5/20 is overridden when VSS is activated.
PS Blank
Patrol Speed Blanking (see Page 14) has two functions. The function used to re-acquire patrol speed is not necessary with VSS
activated. VSS will insure the correct patrol speed automatically.

SPEED RADAR AND THE LAW
FCC Requirements
The Federal Communications Commission requires that all transmitting equipment carry a Grant of Type Acceptance. S DSR
2X
is Type Accepted by the FCC under Type Acceptance number IBQACMI002. The FCC also requires that an operating license be
obtained by the user of the equipment. In the case of local government agencies already licensed under part 90 in the Public Safety
Radio Service, the requirement for a separate authorization for radar speed detection devices was eliminated, effective February 1,
1983, and licensees may operate speed detection devices as part of their base/mobile communications systems. As part of this rule
change, licensees are required to list the number of speed detection units, and the frequencies on which they operate upon renewal of
their land mobile authorizations.

IS MICROWAVE RADIATION DANGEROUS?
The following section has been supplied courtesy of the Food and Drug Administration (FDA).
UPDATE ON POSSIBLE HAZARDS
OF TRAFFIC RADAR DEVICES
July 20, 1992
TO: CITY, COUNTY, STATE, AND FEDERAL POLICE OFFICIALS
Recent stories in the news media have focused attention on the possibility that the traffic radar devices used by police officers might increase their
risk of cancer, particularly testicular cancer. The Food and Drug Administration (FDA) has prepared the following information to inform police
officers about what is known--and what remains unknown--about this question. We urge you to make this Update available to the officers under
your jurisdiction. Feel free to photocopy this Update as needed.
What kind of radiation is emitted by traffic radar units?
These devices emit microwave radiation similar to the type produced inside microwave ovens, but at a power level more than 10,000 times lower.
The radiation travels from the front of the radar device in a narrow, cone-shaped beam, although some of it may be reflected back from hard surfaces
such as metal and glass. The amount of radiation decreases rapidly with distance from the source, so that the farther the devices are kept from the
body, the lower the exposure.
Is there any experimental evidence that the levels of microwave radiation from a traffic radar device can be dangerous?
Although it is known that very high levels of microwave radiation can be harmful, there is no firm experimental evidence at present that the much
lower levels of radiation emitted by traffic radar devices can be hazardous. There are some animal studies that suggest that low levels of radar can
cause biological changes, but it is not known whether these results apply to humans. Also, most of these studies were done with a different type of
microwave radiation than that produced by traffic radar devices.
What about the cancers that have occurred in police officers who used traffic radar devices for long periods of time?
It is true that some officers who have used these devices have experienced cancer. But it is important to understand that these types of cancers also
occur among people who haven’t used radar devices. That’s why it is not possible to tell whether any individual officer’s cancer arose because of
the radar, or whether it would have happened anyway. The key question is whether the risk of getting a particular form of cancer is greater
among people who work with the radar devices than among the rest of the population. And the only way to answer that question is to compare
the cancer rates among radar- using police officers with people who don’t work with radar, or with the cancer rates that would be expected in the
general population.
FDA has made a preliminary comparison between the number of cancers reported in police officers who use traffic radar devices and cancer rates in
the general population. Based on case reports we have so far, the comparison does not appear to show a greater cancer rate among the police, but it is
too soon to conclude that there is no risk.
What’s FDA doing to address the question of cancer risk?
FDA will continue to evaluate the research performed by microwave scientists around the world to see if their results apply to traffic radar devices.
In addition, FDA will work with police organizations to collect more data about the cancer experience of police officers, to see whether they are
developing more than the expected number of cancers. To assist us in this effort, any known cases of cancer in police officers using radar should be
reported to FDA by calling 1-800-638-6725. Be sure to provide as much information as possible, including the type of radar unit used, how long the
individual worked with radar devices, and the specific type of cancer.
In the meantime, what can be done to reduce the risk, if there is one?
Although it is not known for sure whether traffic radar devices can produce health problems, police officers can take some simple steps which will
sharply reduce their exposure to the low-level microwave radiation which these devices emit.
1. Always point the device away from your body, or your partner’s body, while it is turned on.
2. Mount fixed radar antennas so that the beam is not pointed at any occupant of the patrol car.
3. Whenever possible, turn off a hand-held unit when it is not in use. If your unit has a "standby" mode, always use it when not measuring the speed
of a vehicle. Never rest the unit against your body when it is turned on.
4. When it is on, try to avoid pointing the device toward metal surfaces inside your car, such as the floor or a door, to avoid microwave reflection.
(Measurements have shown that the radiation reflected from nonmetallic surfaces, such as glass in the car’s windows, is much less intense than
that reflected from metal surfaces.)
Again, there is no proof at this point that traffic radar devices can be harmful to the police officers who use them. Future information may reveal that
these devices are indeed harmless. But until the question is settled, taking the simple precautions outlined above should reduce any possible risk. In
the meantime, FDA will continue to provide updates as more information becomes available.

STALKER DSR 2X MICROWAVE EMISSIONS
The S DSR 2X Radar operates with a nominal power output of 15 mw and a maximum of 50 mw of power output and emits
low level, non-ionizing radio frequency electromagnetic radiation. The American National Standards Institute (ANSI) has the
responsibility for establishing standards with respect to human exposure to radio frequency electromagnetic radiation. The current
ANSI C95.1 standard in effect, for frequencies from 1500 MHz to 100,000 MHz, specifies a maximum exposure power density of 5.0
mw/cm² (.005 Watt/cm²) on any part of the body. The S

DSR 2X has a maximum power density of 2.0 mw/cm² that is well
REQUIRED MAINTENANCE
No user maintenance is required on the S DSR 2X. However, if any problems are experienced during testing procedures or
normal operation, the unit should be taken immediately to your department’s radar specialist to determine the extent of the problem.
If a malfunction has occurred, the unit will require servicing. Normal care should be taken by the user in handling the S
2X
to preserve the life and usefulness of the equipment.

Radar suffers from patrol speed shadowing
If the patrol window indicates an incorrect patrol speed, the PS BLANK key blanks the patrol speed window and acquires a new
patrol speed. See Patrol Speed Shadowing Effect on Page 28.
Through the Operator Setup Menu, change the low-end patrol speed from 5 mph to 20 mph, thus preventing patrol speed tracking
below 20 mph. It is not possible to allow patrol speed tracking below 20 mph and to eliminate patrol speed shadowing
simultaneously. See Low-End Patrol Speed Selection on Page 22. Install VSS. See page 31.
Radar will not lock onto patrol speeds below 20 mph
Through the Operator Setup Menu, change the low-end patrol speed from 20 mph to 10 or 5 mph. See Low-End Patrol Speed
Selection on Page 22. The radar will now be susceptible to patrol speed "shadowing," which can be easily corrected by pressing
the
PS BLANK key.
Radar has trouble maintaining patrol speed
Mount the antenna higher above the dash and/or point antenna slightly down toward the ground. Make sure the wipers are not in
the radar beam path. Make sure the windshield does not have paint/mask around the perimeter.
