INTRODUCTION
S PATROL is a K-Band speed-measuring radar that can be mounted in a variety of ways, and is operational with
one or two antennas. Utilizing a state-of-the-art Digital Signal Processor (DSP), S PATROL provides a level of
performance, convenience, and accuracy previously unavailable. The DSP performs the critical filtering and timing
functions required for speed measurement in its software, as opposed to its hardware. This provides less unit-to-unit
variation, more reliable performance, and easier maintenance. The unique feature of the S PATROL is that it can be
upgraded in the future by simply reprogramming the flash memory chip, preventing obsolescence!
S PATROL operates in K-Band (24.15 GHz) and provides a hold mode. Both K-Band operation and the hold
feature reduce the possibility of detection by radar detectors. Target-speed locking, Track-thru-Lock speed, Faster Speed
Tracking, and the Doppler audio capability assist the operator in positive target identification and provide operating
convenience.
INSTALLATION
S PATROL consists of a counting unit with integrated display; one or two antenna units; and a wireless/wired
remote control unit. S PATROL is powered from the 12-volt vehicle power system using a Power Cable from the
counting unit. Each system 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 K-Band antenna units are fully
waterproof and can be installed outside the vehicle, if desired. The counting unit with display, and remotes are not
waterproof and must be installed in a location sheltered from the weather. Longer cables are available from the factory for
specific installations, if needed.
Display/Counting Unit - To mount the counting unit, connect the Power Cable to the power jack on the back of the
counting unit. Plug the front and/or rear antenna cables into the back of the counting unit. If using only one antenna, plug
it into the front jack. 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 unit.
Antenna Unit - The radar can consist of either one or two K-Band antennas. Before proceeding with the final
installation, check the intended mounting locations for fan interference on both antennas. See the section on fan
interference, page 17. 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, if desired.
Cordless Ergonomic Remote Control - The only installation required for the ergonomic remote control is to install
the 3V Lithium battery (type 123). 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. This remote control can be used in a wired
mode. 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.
THEORY OF OPERATION
Stationary Mode - S PATROL uses the Doppler frequency shift technique to measure the speed of moving
vehicles. This technique is based on the Doppler Theory, 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 S
PATROL processes the reflected signal to obtain the frequency shift. The Digital Signal Processor (DSP) then measures the
frequency shift to obtain the target speed. In stationary mode, the transmitted signal strikes a moving target and is reflected
back to the antenna. S PATROL processes the signal to obtain the target speed. Targets, both approaching and
receding, generate the same Doppler frequency shift; therefore, targets traveling both directions can be measured.
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 passing stationary objects. Since the
Doppler shift is proportional to the relative velocity between the radar and the passing reflecting objects, 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 and then returning 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 PATROL subtracts the patrol speed from the closing speed.
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 passing stationary objects. Since the Doppler
shift is proportional to the relative velocity between the radar and the passing reflecting objects, the Doppler shift of this
signal will be proportional to the speed of the patrol vehicle.
The second signal, difference speed, results from the radar signal reflecting from an approaching or retreating same lane
moving target and then returning 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 and
the faster mode is selected (default), the difference speed will be added to patrol speed to obtain target speed. If the target
vehicle is moving slower than the patrol vehicle, SLOWER option should be selected. In this case, the difference speed
will be subtracted from the patrol speed to obtain target speed. For more detailed information, see the section on SAME
LANE THEORY, page 14.
Faster Mode - S PATROL offers Faster Speed Tracking. Fast Speed Tracking is a field selectable feature and
can be easily disabled, if desired.
The addition of the faster 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 moving eighteen wheeler: The faster sports car, although clearly speeding, previously
could not be measured because the strongest truck target captures the target display window. S PATROL, in this
example, will display the speed of the strongest truck in the target window, while the speed of the faster sports car will
appear in the middle faster window. Tracking of both targets may be performed simultaneously. (See page 13.)

Display Unit Functions
PWR:
The PWR switch is the main On/Off power switch.
TARGET WINDOW:
The left, three-digit LCD window is the target window. This window displays the
speed of targets entering the radar beam. While in stationary mode, the target window
will show the speed of the strongest approaching or the strongest receding target
relative to the radar. In opposite lane moving mode, the target window will show the
speed of the strongest opposite lane approaching target or the strongest opposite lane
receding target. In same lane moving mode, the target window will show the speed of
the strongest same lane faster (front or rear) target or the strongest same lane slower
(front or rear) target. See SAME LANE THEORY, page 14.
MIDDLE WINDOW:
The middle, three-digit LED window is a dual purpose window. First, it is used for
locking the strongest target shown in the left window. In addition, the middle window
is used to display the faster target in the radar beam. The LOCK and FAST icons are
used to indicate the current use of the window.
The middle window is used to store target speeds that the operator chooses to "lock"
using the LOCK/REL key. The presence of the LOCK icon indicates that the middle
window contains a "locked" target speed.
When the faster mode is selected and when no LOCK target is present, the middle
window is used to track the faster target in the radar beam. Faster mode is turned on
and off by using the menu button. The presence of the FAST icon indicates that the
faster mode is selected.
PATROL WINDOW:
The right, three-digit LCD window is the patrol window. In moving mode, the
operator should always verify that the patrol window is tracking the patrol vehicle's
speedometer. After locking a target speed, the patrol window may be "blanked" by
pressing the PS BLANK key. Restore the patrol speed by pressing the PS BLANK
key a second time.
XMIT:
The XMIT icon indicates that S

SLOW:
The SLOW icon indicates that the radar is in slow target same lane mode. Conversely,
fast target same lane mode is indicated by the absence of the SLOW icon. See SAME
LANE THEORY, page 14.
SAME:
The SAME icon indicates that the radar is in same lane mode. Conversely, opposite
lane mode is indicated by the absence of the SAME icon. See SAME LANE
THEORY, page 14.
LOCK:
The LOCK icon indicates that the operator has locked a target speed in the center
window.
Audible Indicators
Antenna tones - Different audio tones are used when switching between the front and the rear antenna. A 1-beep tone
corresponds to the front antenna, while a 2-beep tone corresponds to the rear antenna.
Faster tone - Different audio tones are used when turning the faster mode on and off. A high-pitched beep tone (for
fast) indicates that faster mode is selected. A normal beep tone indicates that faster mode is turned off.
Self-Test tones - A 4-beep “happy” tone indicates the successful completion of a self-test operation. A 15-beep tone
indicates a failed self-test.
Automatic Self-Test - An automatic self-test (indicated by a 4-beep “happy” tone) is performed every 15 minutes while
S PATROL is transmitting.
NOTE: If for any reason “FAIL” comes up on your S PATROL Radar, the unit must be turned OFF and then back
ON to reset the FAIL mode. As an example, if you did not properly attach the antenna cable and the word “FAIL”
appeared, it would be necessary to correct this problem, to properly connect the cable, then turn the power OFF and then
back ON. The word FAIL should not reappear.
ERGONOMIC REMOTE CONTROL FUNCTIONS

The ergonomic remote control shown above is the standard control supplied with the S PATROL radar unit. Other
optional remotes with a different cases and key configurations are shown on later pages.
LOCK/REL:
MOV STA /MENU:
SAME/OPP:
ANT:
In Radar Mode, the LOCK/REL key alternates between target lock and release
functions. The first time the LOCK/REL key is pressed, with a speed in the target
window, that strong target speed is transferred to the middle window and locked along
with the present patrol speed. This state is indicated by the illumination of the LOCK
icon. Pressing LOCK/REL a second time clears the locked contents of both the lock
and the patrol windows.
During lock, the LOCK icon will light. The target window and Doppler audio remain
active after locking.
This is a dual function key. The normal function is to toggle between MOVING and
STATIONARY modes: A speed or a [ ] in the patrol window indicates moving mode,
while a blank patrol window indicates stationary mode.
The SAME/OPPOSITE key is used to alternate between same lane moving mode and
opposite lane moving mode. The SAME icon toggles on and off to indicate same lane
mode.
The ANT key is used to switch between the front and rear antennas, unless the radar
was factory set for only one antenna. The FRONT or REAR icon will light. The
display unit can sense the presence or absence of the front or rear antenna. A steady

missing antenna and/or cable, or a malfunction of the antenna unit.
The XMIT/HLD key toggles between XMIT (transmit) and HLD (standby). The
XMIT icon will light for transmitting and extinguish for hold.
FAST LOCK key alternates between faster target lock and release functions. Pressing
the FAST LOCK key with a faster speed in the middle window will lock the faster
speed along with the present patrol speed. This state is indicated by the illumination of
both the FAST and LOCK icons. Pressing FAST LOCK key a second time clears the
contents of both the lock and the patrol windows. During fast lock, the target window
and Doppler audio remain active.
In same lane mode, the SLOWER key is used to toggle between fast target same lane
mode and slow target same lane mode. See SAME LANE THEORY section, page 14.
The SEn key is used to adjust the range up or down at any time. Maximum range
(sensitivity) is SEn 4, minimum range (sensitivity) is SEn 1. The range (or
sensitivity) must be set separately for same lane moving mode and opposite lane
moving mode. While in each mode, (same lane and opposite lane/stationary), indicated
by the presence or absence of the SAME icon, set each sensitivity as described above.
SQL:
The SQL key toggles the squelch override on and off. In the normal position (squelch
on), audio will be heard only when a target is being tracked.
PS 5/20:
The PS 5/10/20 key is used to select one of the three selections for low end patrol
speed of either 5, 10 or 20 mph. For example: a patrol window indication of 20 starts
tracking patrol speed at 20 mph, while a patrol window indication of 5 starts tracking
patrol speed at 5 mph. If the VSS feature is enabled (see section titled “VSS OPTION”
on Page 21), the PS 5/10/20 key will only display SP when pressed.
SELF TEST:
The SELF TEST key performs a diagnostic check on the display/counting unit and
antenna. The display/counting unit will complete a display segment test, processor
check, and crystal check, followed by the display of speeds of 10, 35, and 65; and
ending with a display of the display/counting unit internal operating temperature in
degrees Fahrenheit (e.g., 110 °F) (if the unit has been ordered in kilometers, the
temperature will be displayed in Celsius (e.g., 35 °C)), and input battery voltage (e.g.,
bAt 13.8). A comprehensive test is also performed on the selected antenna by the
counting unit to ensure the integrity of the antenna cable and antenna electronics.
PASS or FAIL is indicated on the display unit after all tests have been completed.
(Target Doppler)
The
key is used to adjust the volume of the Target Doppler audio up or down.
Press the ▲ or ▼ key to make the display step from Aud 0 to Aud 9 where Aud 9 is
the loudest.
(Beep Tones)
The
key is used to adjust the volume of the beep tones. Press the▲ or ▼ key to
make the display step from bEEP 0 to bEEP 9 where bEEP 9 is the loudest. The
Patrol Speed window will display the beep volume level.
PS BLANK:
This is a dual function key. If the patrol window indicates an incorrect patrol speed,
the PS BLANK key blanks the patrol speed window and acquires a new patrol speed.
The PS BLANK key also blanks the patrol speed after the target speed and patrol
speed are locked. Press PS BLANK again to restore the blanked speeds.
LIGHT
This is a dual-function key. With a single depression, the LIGHT key activates the
remote control keyboard back light for six (6) seconds. Two rapid depressions of the
LIGHT key activate the display unit’s brightness control. Additional depressions of
the LIGHT key toggle the display intensity through six levels of brightness, ranging
from bri 1 (low) to bri 6 (high). In the switched display only, an automatic brightness
compensation setting of bri A will appear in the sequence of manual brightness
settings.
Counting Unit - The counting unit is not waterproof, therefore, you should mount the counting unit in an out-of-theweather location. Plug the front and/or rear antenna cables into the back of the counting unit. If using only one antenna,
plug it into the front jack. Plug the power cord from the counting unit into the cigarette-plug receptacle.
Antenna Unit - 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 with the second
antenna, if desired.
Remote Control - Follow the instructions below for your particular remote:
1.
Infrared Remote - the only installation for any of the infrared remote controls is to install either the Lithium
battery or 2 AA batteries, depending on model. Remove the battery compartment cover by sliding it away
from the case. Install the two batteries, paying attention to the polarity markings. Replace the battery cover
by sliding it onto the case until it snaps into place.
2.
Corded Remote - attach the corded remote control to the counting unit using the power cord with a serial port
OPERATING THE STALKER PATROL
Stationary Mode Speed Measurement
Perform the tuning fork test on the radar before using for traffic
measurements. See page 20 for instructions on this procedure.
Select stationary mode by pressing the MOV/STA key on the remote
control, then select the desired antenna by pressing the ANT key. To
transmit, press the XMIT/HOLD key. The XMIT icon should
appear on the display unit (Fig 3) indicating that a radar signal is
being transmitted.
If a target is in range, such as one traveling 54 mph, the speed will
appear in the target window of the display unit (Fig 4); and a Doppler
audio tone, which is proportional to the target speed, will be heard
from the speaker. The target speed is continually measured and
displayed, and the Doppler audio tone is heard as long as the target is
present.
Hold mode can be selected by pressing the XMIT/HOLD key on the
remote control. In hold mode, The XMIT icon will be off
(Fig 5) and no signal will be transmitted, preventing detection by
radar detectors.

Opposite Lane Moving Mode Speed
Measurement
Perform the tuning fork test on the radar before using for traffic
measurements. See page 20 for instructions on this procedure.
Select moving mode by pressing the MOV/STA key on the remote
control. When S PATROL is in moving mode, the patrol
window will contain either the patrol speed or a [ ]. The [ ] (Fig 6)
indicates that S PATROL is in moving mode, but has no
ground speed.
Select opposite lane mode by pressing the
SAME/OPP key until the SAME icon is not visible. To transmit,
press the XMIT/HOLD key. The XMIT icon should appear on the
display unit (Fig 6) indicating that a radar signal is being transmitted.
Be sure the patrol speed indicated corresponds to the speedometer of
the patrol vehicle. If an approaching target is in the radar beam, its
speed will appear in the target window and a Doppler audio tone will
be heard from the speaker. Fig 7 is an example in which the patrol
speed is 50 and the approaching target speed is 68. The target speed
is continually measured and displayed and the Doppler audio tone is
heard while the S PATROL is in transmit mode and a target is
present.

radar detectors. When in hold, S PATROL remembers the last
patrol speed and looks for that speed first when changing from hold
back to transmit.
NOTE: While operating in VSS mode (see section titled “VSS

Same Lane Moving Mode Speed Measurement
Perform the tuning fork test on the radar before using for traffic
measurements. See page 20 for instructions on this procedure.
Patrol speed is especially important while operating in the same lane
moving mode. The patrol vehicle should be traveling slower or faster
than all targets in the radar beam. Normally, traveling slower than all
same lane targets is recommended.
To transmit, press the XMIT/HOLD key. Select same lane moving
mode by pressing the MOV/STA key, then select same lane mode by
pressing the SAME/OPP key. Same lane mode is selected when the
SAME icon is visible (Fig 9). Note: When Same Lane is selected, the
sensitivity is automatically reduced internally by software. A
sensitivity setting of 4 is recommended in Same Lane.
If a same lane target is in the radar beam, its speed will appear in the
target window and the difference speed audio will be heard from the
speaker. The target speed is obtained by adding the difference speed
to the patrol speed. Fig 10 is an example of a patrol speed of 50 and a
faster same lane target in front of the patrol vehicle traveling at 68.
The target speed is continually measured and displayed and the
Doppler audio tone is heard while the S PATROL is in
transmit mode and a target is present.
For targets in the radar beam that are traveling slower than the patrol
vehicle, it is necessary to press the SLOWER key. Fig 11 is an
example of a patrol speed of 50 and a slower same lane target in front
of the patrol vehicle traveling at 48.
NOTE: To verify that the SLOWER key is in the right position,
change the speed of the patrol vehicle by 2 - 3 mph, observing that the
displayed target speed does not change.

Patrol Speed Shadowing Effect
Traditional radar units exclude patrol speed lock-on and tracking below 20 mph. One of the unique features of S
PATROL is that it allows patrol speed lock-on and 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 PATROL is more
prone to "shadowing." Shadowing occurs when a 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.
S PATROL has three options for eliminating the shadowing effect: (1) make the unit re-acquire the correct patrol
speed by pressing the PS BLANK key, (2) change the low-end patrol speed from 5 mph to 20 mph (see following
paragraph for instructions), and (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.
Low-End Patrol Speed Selection
The PS 5/20 key is used to set the low-end patrol speed. The right
two digits of the patrol window refer to the current low-end patrol
speed of either 5 mph, 10mph, or 20 mph. For example, sensitivity 1
with
5 mph low-end patrol speed would be indicated by: SEn 1
(Fig 12). Sensitivity 1 with 20 mph low-end patrol speed would be:
SEn 1 20 (Fig 13). During VSS operation this function is not
required and thus is not available. During VSS operation, when the
PS 5/20 key is pressed, SP will be momentarily displayed.

Doppler Audio
When a target is being tracked, a Doppler audio tone can be heard
from the speaker. The pitch of this tone is a precise indication of
target speed. The tone quality is useful for judging possible
interfering or multiple targets.
In opposite lane moving mode, S PATROL compensates for
patrol speed variations when generating the Doppler audio. Since the
audio tones do not vary with patrol speed, the operator soon learns to
correlate the Doppler audio with the target speed. This eliminates the
need of constantly watching the display to determine target speed. In
same lane moving mode, S PATROL generates difference
audio instead of the true audio described above. The difference audio
gives a direct indication of the difference in speed between the patrol
vehicle and the target vehicle.
The speaker volume can be adjusted through 10 levels by pressing the
key and ▲ or ▼ on the remote control. Maximum audio volume
is indicated by Aud 9 (Fig 18), and audio off (an optional factory
setting) is indicated by Aud 0 (Fig 19).

FASTER SPEED TRACKING THEORY
The following examples are Faster targets under various conditions. The Faster mode has to be toggled "ON" by pressing
the FASTEST key. The key does not have to be held or depressed. In addition to the speeds displayed in each window,
carefully note the icons illuminated.
The addition of the Faster mode allows S PATROL to track a smaller high-speed target that was previously
undetectable because a stronger target shielded the weaker (smaller) target from normal 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 PATROL
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 PATROL simultaneously tracks both targets: however, the target window is always reserved for the strongest
target and the Faster window is reserved for the Faster target. When the Faster target becomes the strongest target, the
Faster target’s speed will transfer to the strongest target window. The Faster target’s speed can be locked only when it
becomes the strongest target. The result is better tracking for better court testimony! See the examples on the next page:

appears in the target window and the 72 mph Faster target (the sports
car) appears in the middle window (Fig 27). The Faster target cannot
be locked unless it becomes the strongest target and appears in the left

The 60 mph strongest target can be locked, by pressing the LOCK
key (Fig 28). Note how the middle window changes from a Faster
window to a Lock window. The FAST icon has been replaced by the
LOCK icon. The middle window is therefore defined by the icon that

SAME LANE THEORY
Same Lane Operation
1.
To transmit, press the XMIT/HOLD key. The XMIT icon should appear on the display indicating a radar signal is
being transmitted.
2.
Select moving mode by pressing the MOV/STA key on the remote control. When S PATROL is in moving
mode, the patrol window will contain either the patrol speed or a [ ]. The [ ] indicates that S PATROL is in
moving mode, but has no ground speed. Be sure the patrol speed indicated corresponds to the speedometer of the
patrol vehicle.
3.
Then select same lane mode by pressing the SAME/OPP key. Same lane mode is selected when the SAME icon is
visible.
4.
If a target is in the radar beam, its speed will appear in the target window and a Doppler audio tone will be heard from
the speaker.
5.
Patrol speed is especially important while operating in the same lane moving mode. The patrol vehicle should be
traveling slower or faster than all targets in the radar beam. Normally, traveling slower than all same lane targets is
recommended. After visually estimating the speed of the targets in the radar beam, press the SLOWER key to
correspond to whether the observed targets are traveling faster or slower than the patrol vehicle. The SLOW icon
indicates that the target is traveling slower.
6.
To verify that the SLOWER key is in the right position, change the speed of the patrol vehicle by 2-3 mph, observing
that the displayed target speed does not change.
Doppler Signal Processing
Example
Two signals must be processed to determine target speed. The first signal,
patrol speed, results from the radar signal reflecting from passing stationary
objects. The Doppler shift of this signal will be proportional to the speed of
the patrol vehicle, since Doppler shift is proportional to the relative velocity
between the radar and the passing reflecting objects.
Patrol Speed = 55 mph
The second signal, difference speed, results from the radar beam reflecting
from a slower or faster same lane moving target and then returning to the
patrol vehicle. The Doppler shift of this signal will be proportional to the
difference speed between the patrol and target vehicles. The audio tones heard
while in same lane mode are directly related to this difference speed.
Difference Speed = 10 mph
The radar is unable to distinguish between a difference speed resulting from a
faster or slower target. The operator must tell the radar how to process this
signal by pressing the SLOWER key. If the target vehicle is moving faster
than the patrol vehicle, the difference speed must be added to patrol speed to
obtain target speed. If the target vehicle is moving slower than the patrol
vehicle, the difference speed must be subtracted from the patrol speed to obtain
target speed.
For faster target:
Target = 55+10 = 65
14
For slower target:
Target = 55-10 = 45
The operator selects either addition or subtraction by pressing the SLOWER
key on the remote control while observing the SLOW icon on the display.
When the SLOW icon is off, the counting unit adds the difference speed to the
patrol speed to obtain target speed. When the SLOW icon is on, the counting
unit subtracts the difference speed from the patrol speed to obtain target speed.
For faster target:
SLOW icon is OFF
For slower target:
SLOW icon is ON
NOTE: To verify that the SLOWER key is in the right position, change the
speed of the patrol vehicle by 2 - 3 mph, observing that the displayed target
speed does not change.

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
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 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.
Fan Noise
As you will discover, the S PATROL that you have purchased is extremely sensitive resulting in longer range. This
extra sensitivity may allow you to pick up fan noise when operating the radar from inside the patrol vehicle.
Fan noise is a common Doppler radar problem when aiming the antenna through a window from inside the patrol vehicle.
A small amount of the radar beam is reflected off the glass back into the vehicle. This may allow the radar to pick up fan
noise from within the patrol vehicle.
The problem is not a problem with the radar, but with the location of the radar's antenna. Doppler radar is designed to
detect moving or vibrating objects; therefore, it may detect any moving or vibrating surfaces inside the patrol vehicle, such
as the fan or a dashboard that is vibrating from the fan. Fan interference 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 only a problem when operating in
stationary mode or when operating in moving mode with patrol speeds less than 30 mph.
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 a corner of the dash away
from the fan. The lower left side of the dash is a recommended location.
2.
Insure 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 inside glass as possible (preferably less than 1/2 inch).
4.
Turn the fan off while operating the radar in stationary mode or moving mode with patrol speed under 30 mph.
5.
Install an optional Antenna Port on the glass surfaces directly in front of the antenna. The specially designed Antenna
Port consists of two white discs, 3 1/2 inches in diameter, with double-sided tape on one side. Attach one disc on the
inside glass surface, and the other disc on the outside glass surface. Due to interference with windshield wipers, the
Antenna Port can only be installed on the rear window.
6.
If the above suggestions fail, mount the antenna completely outside the vehicle.
17
Interference From Other Transmitters
Strong signals from nearby radio transmitters may interfere with
operation of S PATROL. The RFI indicator (Fig 34) signals
that an interference source has been detected. Speed readings are
inhibited when this occurs to prevent the possibility of false
readings. The interference source may be the vehicle’s two-way
radio, another nearby transmitter, or an illegal radar-jamming
device.

Power Supply
A low voltage condition from the vehicle's electrical system will
cause a Lo V indication (Fig 35), 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 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.

No Power
If you get no power to the unit, first check the fuse in your radar by
unscrewing the silver contact tip at the bottom of the cigar plug and
removing the fuse. Check the fuse to see if it has blown. If so,
replace with a new fuse and try to locate the cause. If the fuse is
okay, check the fuse to the vehicle’s cigar plug. If this fuse is also
okay, place the radar in a different vehicle or try a different radar in
your vehicle.
TESTING
In order to ensure continued compliance with FCC rules, meet legal requirements for admissibility of radar speed
measurements, and verify full operating performance, the following test procedures are recommended. If the unit fails any
of the tests, it should be removed from service until the cause of the problem is corrected.
Periodic Calibration
We recommend that the following performance characteristics should be verified on a regular basis:
1.
2.
3.
Transmitter frequency is within specification on licensed operating frequency.
Unit indicates correct speed (± 1 mph) when reading a target of known speed.
Unit detects targets of good reflectivity over unobstructed, flat terrain at distances of 1/2 mile, or more, when set for
highest sensitivity (SEn 4).
Power-On Self-Test
Each time the unit is powered on, an automatic self-test is performed
to verify that the unit functions. The display indicates 888 888 888
(Fig 36) during the test. A 4-beep “happy” tone indicates the
successful completion of this test. If a problem is detected, FAIL

only the selected antenna is tested, it is necessary to perform this test
twice -- once with the front antenna selected, and once with the rear
antenna selected.
The display/counting unit will first complete a processor check,
memory check, and crystal accuracy check; followed by the display
of speeds of 10, 35, and 65 (Figures 37, 38, and 39); and ending with
a display of the display/counting unit internal operating temperature
in degrees Fahrenheit (e.g., 110 °F) (if the unit has been ordered in
kilometers, the temperature will be displayed in Celsius (e.g., 35
°C)), and input battery voltage (e.g., bAt 13.8) (Fig 40 and Fig 41,
respectively).
A comprehensive test is also performed on the selected antenna by
the display/counting unit to ensure the integrity of the selected
antenna cable and antenna electronics. After all the tests are
completed, PASS (Fig 42) along with a 4-beep “happy” tone
indicate successful test completion. FAIL (Fig 43) along with a 15beep tone indicates a failed self-test.
Note: We recommend that the internal circuit test be performed on

(press XMIT key). Strike the 25 mph tuning fork against a hard
nonmetallic surface, such as the heel of a shoe. Quickly hold the
tuning fork approximately two (2) inches in front of the antenna,
with the narrow edge of the fork facing the antenna. The target
window should indicate 25 ± 1 mph (40 kph) (Fig 44). Repeat the
above test with the 40 mph (64 kph) tuning fork. Select the rear

Moving-Vehicle Test
A moving-vehicle test can be performed as an additional check of performance and accuracy. While driving a patrol
vehicle, with an accurately calibrated speedometer, aim the antenna down an empty highway directly in front of the
vehicle. The speed indicated by S PATROL should match the speedometer indication to within a small error
(depending on speedometer accuracy). This test is optional and is not a substitute for the tuning fork test, but is a good
overall indication of proper operation of the unit.
VEHICLE SPEED SENSOR (VSS) OPERATION
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 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.” The simplest way to monitor tire rotation is to attach to the Vehicle Speed
Sensor (VSS) signal in the patrol vehicle.
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 PATROL 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.
The Result is PERFECT Patrol Speed
•
•
•
The radar will never shadow.
It tracks and acquires patrol speeds from 1-200 mph.
Moving / Stationary selection becomes automatic.
VSS Cable Installation
To take advantage of VSS patrol speed steering,
requires two cables that are provided with the VSS
Option.
The vehicle VSS cable (PN 155-2179-00), 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 6-pin 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.
21
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.
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 MOV/STA key will not
override the moving / stationary mode selected by the VSS steered radar.
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 PATROL radar will also not be switched
into moving mode until the patrol car exceeds 10 mph.

(2) This device must accept any interference received, including interference that may cause undesired
operation.
Case Law
Legal precedent has clearly established the accuracy, and admissibility of Doppler speed radar evidence. This section on
case law is included so the radar operator can familiarize himself with the more important legal cases involving the use of
Doppler speed radar, and be aware of the guidelines concerning admissibility established by these cases. Much of the
referenced material may be obtained at your local law library or prosecutor's office.
Reference A -- State v. Dantonio (N.J.), 115 A2d 35, 49 ALR 2d 460 The landmark case on the use of traffic radar. This
case sets precedent of the following:
1.
Judicial notice has been taken of accuracy of radar.
2.
A few hours training is sufficient to qualify an operator.
3.
The operator need not understand or be able to explain internal workings of the radar.
Reference B -- Everight v. Little Rock, ARK., 326 SW2d 796: Establishes that the court may take judicial notice of the
reliability of radar.
Reference C -- State v. Graham (Mo.), 322 SW2d 188: Establishes that the court may take judicial notice of the ability of
radar to measure speed.
Reference D -- State v. Tomanelli (Conn.), 216 A2d 625: Reviews the matter of judicial notice; recognizes the ability of
Doppler radar to measure the speed of a motor vehicle; and acknowledges that the tuning fork is a reliable accuracy test.
Reference E -- Honeycut v. Commonwealth (Ky.), 408 SW2d 421: In this appeal, the court rejects, one by one, the
arguments of the appellant that the evidence should not have been admitted; and again establishes the following:
(1) A properly constructed, and operated radar device is capable of measuring accurately the speed of a motor vehicle.
(2) The tuning fork test is an accurate method of determining accuracy of the radar. (3) It is sufficient to qualify an
operator that has such knowledge, and training that enables him to properly set up, test, and read the radar. (4) The
operator is not required to understand the scientific principles of radar, nor explain its inner workings; in addition, the
operator may be qualified to operate the radar after receiving a few hours of instruction. (5) The officer's estimate of
excessive speed, from visual observation, when confirmed by the reading of the radar device and when the offending
vehicle is out-front, by itself, nearest the unit, is sufficient to identify the vehicle, if the officer's visual observations support
the radar evidence.
From the case law above, a successful prosecution may depend on the officer's ability to testify to the following points:
1.
The qualifications and training of the officer.
2.
The time, place and location of the radar device at the time the offense occurred.
3.
The location of the offending vehicle at the time the offense occurred.
4.
The identification of the offending person as the operator of the vehicle.
5.
The identification of the offending person's vehicle.
6.
The visual observation of its apparent, excessive speed.
7.
The vehicle was out-front, by itself, nearest the radar when the reading was obtained.

MICROWAVE RADIATION
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 PATROL EMISSIONS
The S PATROL 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 PATROL has a
maximum power density of 2.0 mw/cm² that is well below the ANSI standard.
REQUIRED MAINTENANCE
No user maintenance is required on the S PATROL. 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 PATROL to preserve the life and usefulness of the equipment.
TROUBLESHOOTING
PWR key does not function
Make sure all cables are mated correctly with their connectors. Check the vehicle cigarette-plug connector for dirty
contacts. Check for a blown fuse in the S PATROL cigarette-plug.
Low or no speaker volume
Press the
key on the remote control to adjust the volume. Aud 0 (off) to Aud 4 (highest level).
Radar has short range
Set range (sensitivity) control to SEn 4 (longest range). Note: Opposite/stationary direction mode and same direction
mode sensitivity settings need to be set independently. See page Error! Bookmark not defined..
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.
Press the PS 5/20 key to change the low-end patrol speed from 5 mph to10 or 20 mph, thus preventing a patrol speed
lock below 10 or 20 mph. It is not possible to allow patrol speed locking less than 20 mph and to eliminate patrol
speed shadowing simultaneously. Shadowing is eliminated when VSS is installed. See Low-End Patrol Speed
Selection.
Radar will not lock onto patrol speeds below 20 mph
Press the PS 5/20 key to change the low-end patrol speed from 20 mph to 10 or 5 mph. See Low-End Patrol Speed
Selection. The radar will now be susceptible to patrol speed "shadowing," which can be corrected with 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.
Radar picks up vehicle fan and reads 5 to 30 mph in stationary mode
Check for proper aiming of antenna. Make sure that the paint/mask or metallic objects are not deflecting the radar
beam down into defroster vents. If so, raise antenna above obstruction. See Fan Noise.
Radar displays LO V icon
Make sure the cigarette-plug is securely installed and the contacts are clean.
Radar flashes Hot in display
The radar is overheating. Move radar out of direct sun. Do not leave radar operating in a closed vehicle.
Radar will not display readings below 10mph
Call Customer Service if this is desired.
