Section 1.0 INTRODUCTION
The Kustom Signals Talon radar system comes from a long standing
commitment to the law enforcement community to provide quality, state-
of-the—art speed measuring equipment. The Talon offers features never
before available on a moving/stationary handheld Ka—Band radar system,
yet allows easy operation and easy one button mode changes.
Since the Talon radar system uses Digital Signal Processing (DSP), it
has available options to the officer which allow same direction speed
detection and fastest vehicle mode, showing the operator the speed of
the strongest and fastest vehicle speeds detected. Along with the
above features, the Talon offers Kustom Signals proven quality and
service to the customer.
This is the smallest handheld, battery operated moving and stationary
radar Kustom Signals has produced. while small size was an important
feature during the design of the Talon, durability was the key issue.
We know police radar equipment, building the first digital traffic
radar unit in 1970. Our history of firsts has never been overshadowed
by the need for durability and a strong case. Things do get dropped.
Our Falcon, HR—12 and other handheld products are designed to meet
these demanding needs. The Talon is no exception and its one—piece
extruded aluminum case protects the electronics not only from shock
and vibration, but from rain and moisture.
All these features and performance standards are packed into this
small, lightweight, battery operated unit. A unit that must be seen
to be believed.

EQUIPMENT MOUNTING
3.3.1 AUXILIARY POWER RECEPTACLE
Cigarette lighter receptacles have been the traditional source of
power for traffic radar over the years. In the newer vehicles,
it is possible that poor grounding of this receptacle, electrical
noise from the vehicle's alternator charging system, electrical
fuel pump and microprocessor noise can combine to create an
unacceptably high level of ambient electronic interference.
AIRBAG CAUTION
Equipment mounted in 1994 or later series police vehicles may
interfere with the operation of passenger side airbags. Information
is available directly from the automobile manufacturers regarding
areas for safe mounting of equipment such as police radar.
since this information will vary by vehicle make and model year,
Kustom Signals recommends contacting the vehicle manufacturer and
following their instructions with respect to mounting of radar units
and other equipment.
For additional mounting suggestions, please contact the Kustom Signals
Customer Service Department.
Kustom Signals cannot accept any liability for equipment which has
been mounted in conflict with the vehicle manufacturer’s
recommendation for proper airbag deployment.
This interference can affect the radar's performance in several
ways: decreased range, no target speeds being displayed or
abnormal tones or noise in the audio. Available for each Talon
radar system is an auxiliary power receptacle, which mounts under
the dashboard and wires directly to the battery.
1. Mount the receptacle in the desired location using the
hardware provided.
2. Connect the black wire to the receptacle’s mounting bracket.
Connect the white wire (with Faston terminal) to the rear
plug of the receptacle. Route the cable through the
firewall and up to the battery.
3. Connect the white wire of the power cable to the battery (+)
positive terminal and the black wire to the (—) negative
terminal.
4. The auxiliary power receptacle is supplied with a 2 amp fuse
to protect the battery should the cable become shorted.
3.3.2 SPEEDOMETER PULSE CABLE INSTALLATION
1. The speedometer pulse cable has a two-conductor connector at
one end and no connection at the other end. The connector
plugs into the mounting pod of the Talon, see Fig. 2, next
to the remote control connector.
2. The inner conductor of the speedometer pulse cable will be
connected to the patrol vehicle’s electrical speedometer
input cable using the splice connector provided. Please
refer to the attached cabling diagrams to identify the
proper vehicle wire location for your particular make, model
and year of vehicle. For additional information, or if your
vehicle is not listed in the diagrams, Contact the vehicle
manufacturer directly.
3. The speedometer interface will be set up later, in Section
6.6.
3.3.3 INDICATOR UNIT (MOVING MODE)
1. The indicator unit consists of the antenna/display unit and
the mounting pod. If required, remove the battery or corded
handle by depressing the release button on the bottom of the
indicator, just behind the rear of the handle and pull the
handle rearward. Refer to Fig. X.
It is recommended that the Talon indicator unit be mounted
on the dashboard of the patrol vehicle within view of the
driver and in a safety zone during airbag deployment.
Please contact the vehicle manufacturer or Customer Service
for suggested mounting locations.
Locate the dash bracket and mounting pod. Secure the
mounting pod to the dash bracket, if necessary and position
in a suitable location on the dash.
Connect the Talon's power cable to the proper power source.
See Section 3.3.1.
Momentarily depress the PWR switch on the rear panel of the
Talon. (Refer to Section 4.1 for location and function of
the switches.) The Talon will process through an indicator
test, internal test and several other reliability tests.
Select the Stationary mode of operation by depressing the
MODE switch, if required. (If the PATROL window is active,
depress the MODE switch.) Only the TARGET will be visible
in the stationary mode.
Momentarily depress the AUDIO. The Target window will
display “Aud” and a number from 0 to 5 indicating the audio
level. with “And” displayed, depress the RANGE switch until
level 4 or 5 is displayed. Also, with “Aud” displayed,
depress the MODE switch , which will unsquelch the audio.
Start the patrol vehicle and position the A/C—heater fan to
a mid—range speed. Move the Talon left or right of it’s
initial location and listen for any raspy sound (fan
interference) in the audio. Position the Talon to minimize
the amount of interference.
When a suitable location is found, secure the dash bracket
to the windshield using the suction cups and Velcro, or
permanently mount the bracket to the windshield.
Position of the antenna:
Moving: Aim the antenna parallel to the ground and
straight down the roadway.
stationary: Unit may be moved on the mount or handheld to
achieve maximum performance and pointed
directly toward the vehicles being monitored.

5.0 GENERAL
The handheld/mounted Talon moving radar system transmits a radio
frequency on Ki—Band, in compliance with the Federal Communications
Commission (FCC) regulations. In stationary, a portion of the
transmitted signal strikes a moving target, traveling toward or away
from the transmitter, and the reflected signal is received at the
antenna. From the antenna, the signal travels to the Digital Signal
Processing (DSP) where it is translated to the speed of the target.
In the moving mode, a portion of the transmitted signal strikes the
surface of the roadway and surrounding terrain and reflects back to
the antenna. The returning signal is the “low” Doppler. From the
antenna, the signal travels to the Digital Signal Processing (DSP)
where it is translated to the speed of the patrol vehicle
(groundspeed) and displayed in the patrol window.
With speedometer pulse input, the DSP compares the indicated patrol
speed from the vehicle's speedometer and is directed to “look" for the
microwave low Doppler signal around this speed, 15 mph (18 km/h). If
a low Doppler signal is found, it is counted and displayed in the
Patrol window, The Talon does not use the speedometer input other
than to direct the DSP toward the desired area.
A portion of the transmitted signal strikes an oncoming vehicle
(target vehicle) and returns to the antenna at a higher frequency
because the two objects (patrol vehicle and target vehicle) are
converging. This returning signal is the “high” Doppler. Then the
Talon measures the speed of convergence, or combined speed, of the
patrol vehicle and target vehicle.
After receiving the “high" Doppler signal, the Talon automatically
computes the difference between the speed of the patrol vehicle and
the target vehicle. The speed of the approaching vehicle registers in
the Target display. If for example, a patrol vehicle is traveling at
50 and an approaching vehicle is traveling at 70, the Talon would
process the groundspeed of 50 and combined speed of 120. The DSP
would subtract the patrol speed from the combined speed to determine
the target speed (l20—50=70). The patrol display would indicate 50
and the target display would indicate 70.
In the Same Direction mode, the “low” Doppler and the “difference”
Doppler signals are received and sent to the DSP. The Difference
Doppler is the speed difference between the patrol vehicle and the
vehicle traveling in the same direction. The Talon will display the
patrol speed then add or subtract the “difference" speed to the patrol
speed for the target speed.
13
Assume the patrol vehicle's speed was 50, and the target was traveling
in the same direction at 70. The Talon would display the patrol speed
as 50 and add the “difference” Doppler signal (20) to the patrol speed
and display 70 in the target display. (50+20=70)
5.1 MICROWAVE RF EMISSIONS
Traffic radar operators may have some questions about the biological
effects of exposure to the microwave energy produced by traffic radar
devices. According to all credible evidence, the emission levels
resulting from traffic radar use pose no threat whatsoever, either to
the radar operator or to target vehicle occupants.
One widely recognized authority for safe limits of nonionizing
radiation exposure 15 the American National Standards Institute, which
recommends maximum exposure levels for the frequencies on which the
Kustom Signals traffic radar systems operate (ANSI/IEEE C95.1—1992,
“Standard for Safety Levels with Respect to Human Exposure to Radio
Frequency Electromagnetic Fields, 3 kHz to 300 GHz"). These exposure
levels, expressed in terms of power density, are 7 mW/cnfi for X-Band
radar, and 10 mW/cmz for K—Band and Ks-Band radar units. Similarly,
the Occupational Safety and Health Administration (OSHA), a division
of the 0.3. Department of Labor, recommends a 10 mW/cnfi exposure limit
for all three frequency bands (“Radiation Protection Guide”, 29 CFR,
Chapter XVII, Subpart G, Part 1910.97). This limit is clearly
accepted by most reputable scientific and medical authorities.
Kustom Signals radar systems utilize microwave transmitters which
produce aperture power densities, measured directly at the face of the
antenna, in the range of approximately 0.3 to 2.3 mW/cnfi. Typical
levels for the vast majority of units are in the 0.4 to 1.0 mW/cnf
range, which is but a small fraction of the recognized safe limits.
Bear in mind that these are level measurements taken directly in the
main beam of the antenna, and that the power densities produced at the
sides and rear of the unit are typically at least one hundred times
lower than in the main beam.
Another reference document on this topic is a DOT publication entitled
“Field Strength Measurements of Speed Measuring Radar Units” (NHTSA
Technical Report “DOT—Hs-805 928). This report documents a series of
tests performed by the National Institute of Standards (formerly the
National Bureau of Standards) on twenty-two (22) commonly used models
of traffic radar units, from six different manufacturers including
Kustom Signals. Aperture power density levels measured were from 0.25
to 2.82 mW/cmz, while back—lobe power density values ranged from 0.001
to 0.02 mW/cmz. These measurements were obtained with the radars
mounted inside vehicles, as in normal operating conditions. Since the
NIST study, other laboratories have duplicated these types of
measurements, producing consistently similar results.

While traffic radar devices do emit microwave energy, the levels are
so low that there are no probable harmful effects. You may use your
Kustom Signals radar unit with complete confidence in its safety, as
well as in its accuracy.

6.0 OPERATION
The internal test and tuning fork tests explained below should be
conducted at the beginning and end of each patrol shift to ensure the
accuracy and functionality of the unit. The results of these tests
may be recorded in a radar log, or officers shift log.
6.1 POWER ON
Momentarily depress the PWR switch. The unit will display all display
segments and perform a test of the internal ROM, RAM and a crystal
cross check to verify the accuracy of the speed processing circuitry.
If these tests pass, the unit will display “32" in the target display
window, stationary mode, or both target and patrol display windows in
the moving mode. This will remain for approximately one (1) second.
The displays will clear and the unit will be operational in the speed
mode.
6.2 AUTOMATIC SELF—TEST
The Talon performs an internal accuracy test whenever the unit's mode
of operation is changed, such as moving to stationary, or upon the
lapse of a maximum time period of 5 minutes, as long as the unit is
powered up. In addition, this self—test will be initiated each time
the target speed is locked.
This test is automatic and will not interfere with any radar speed
readings being taken. The test does not appear in the displays, but
if an error is detected, the target display will indicate “ERR" and
further speed readings will be inhibited.
6.3 MmNUAL TEST
The operator can depress the Test switch at any time during normal
radar operation to perform the indicator and internal tests as
described in the following section.
If either the manual or automatic internal tests fail, “ERR" will be
displayed in the Target window and no further speed readings will be
displayed‘ The unit should be removed from service and sent to an
authorized service center for repair.
16
6.4 ACCURACY TESTING
6.4.1 STATIONARY MDDE
Depress the Mode switch, if necessary to place the Talon in the
stationary mode (only the Target display will be indicated). The
Talon is automatically placed in the stationary mode when the
handle, corded or cordless, is attached.
Momentarily depress the Test switch. The indicator test
will be performed followed by the display of
“32” in the Target window indicating the
internal crystal cross-check has been
successfully completed. The unit will return
to normal stationary radar mode.
6 . 4 . 2 MOVING MODE
Depress the Mode switch, to place the Talon in the
moving mode. Both the Target and Patrol displays will be
indicated. momentarily depress the Test switch. The unit
will proceed through the indicator and internal tests as

will display 32.
INTERNAL TEST TOLERANCE: 0
6.5 TUNING FORK TESTING
Supplied with the Talon are two tuning forks, 30 and 55 mph (45 and BO
km/h). These tuning forks will simulate moving vehicles in the
stationary, moving opposite and moving same direction modes.
The tuning fork tests should be conducted in an area with no traffic.
If this is not possible, point the Talon upward to avoid reflections
from moving vehicles.
6.5.1 STATIONARY TUNING FORK TEST
1. Place the Talon in the stationary mode of operation..
2. Verify the range level is set a maximum. Depress the Range
switch to display “rnG”, then use the UP arrow to increment
the range level to maximum.
3. Lightly strike the lower speed tuning fork on a hard,

Verify that the tuning forks are the proper tuning forks
supplied with the unit.
Striking the tuning fork too hard or on a metallic surface
will cause spurious overtones from the tuning fork. This
may cause the speed readings to be double the specified
speed. Also, moving the tuning fork while in front of the
antenna may cause the speed reading to be slightly lower or
higher than specified. These readings are only momentary
and the proper readings should appear as the false overtones
dissipate.
Ensure that the Talon is in the transmit mode and the range
control is set to maximumi
If the proper readings cannot be obtained, remove the unit
from service and send to an authorized service center for
repair.
6.6 SPEEDOMETER VERIFICATION
The initial use of the Talon with speedometer pulse input
requires the radar unit to be synchronized with the speedometer.
1.
After installation and initial testing with tuning forks,
the Talon should be driven at a constant speed, between 30
and 70 mph (48 and 112 km/h). Depress the Patrol Blank
switch on the remote control two Q1 times. “She" will
appear in the Target window and low Doppler patrol speed
will appear in the Patrol window.
Verify the patrol speed displayed is correct, cross check
with the speedometer reading, and depress the Lock/Release
switch. This tells the DSP processor that the current
speedometer reading and the low Doppler patrol speed reading
agree, within speedometer tolerance limits.
After approximately, two (2) seconds, a synchronization
number will appear in the Lock window. For a Ford Crown
Victoria, this number will be between 28 and 30. This
indicates the Talon is reading and comparing the speedometer
speed input and the true low Doppler patrol speed.
19
6.7
ONLY THE TRUE LOW DOPPLER SPEED SIGNAL IS USED FOR PATROL
SPEED. THE SPEEDOMETER INPUT IS USED ONLY T0 STEER OR GUIDE
THE DSP TO “LOOK” FOR THE LOW DOPPLER SIGNAL IN A SPECIFIC
AREA, IGNORING OTHER SIGNALS.
During normal operation, at patrol speeds below the minimum
limit of 10 mph, 16 km/h, or when a “low" Doppler signal
cannot be found, the Patrol window will display two dashes
(——), indicating that the speedometer speed is being
received but a patrol speed cannot be found or displayed.
As an example, a patrol vehicle is slowing down and as the
speed passes the minimum speed, dashes will be displayed.
MINIMUM PATROL SPEED SET
The Talon allows the operator to set a minimum patrol speed
of 10, 20, 30 or 40 mph (16, 32, 48 or 80 km/h). This
feature will only be active when the speedometer input
feature is not used.
To activate this feature, place the unit in the moving mode
and depress the Patrol Blank switch one (1) time. The unit
will display “Pat" and the last selected minimum patrol
speed will be displayed. Default is the lowest value.
This value will remain for approximately two (2) seconds
unless the remote's Lock/Release switch is depressed, which
increments the speed value. Once the proper minimum value
is selected, the unit will time out in two (2) seconds and
the last displayed value will be accepted as the new minimum
patrol speed.
To display the existing minimum patrol speed, depress the
Patrol Blank switch one (1) time. The current minimum
patrol speed will be displayed in the Patrol window. After
two (2) seconds, the Talon will return to normal operation.
20
6.8 MOVING MODE TEST
Verification of speed readings between the patrol vehicle’s
speedometer and the Talon’s patrol speed display is another
accuracy test that can be performed. These readings should be
the same, or within reasonable limits, allowing for minor
speedometer error.
If a discrepancy is found, the radar unit should be removed from
service until the error can be corrected.
21
7.0 OPERATING MODES
The Talon radar system offers the operator one of the most versatile
handheld K.—Band traffic radar available today. This versatility
allows the operator to monitor traffic traveling in both directions in
the stationary mode, and both directions while the patrol vehicle is
moving, using opposite and same direction modes.
The following guide to operating the Talon radar system is not
intended to be a training program. Before operating this unit
or any other traffic radar system, Kustom Signals urges all
operators to have prior training in radar speed monitoring
devices. Such courses are offered by Kustom Signals, various
state and local agencies and either IPTM (Institute of Police
Technology and Management) or Northwestern University. Contact
your District Manager for further details.
7 . 1 Setup
The Talon may he used with a corded handle, requiring external
power from a portable battery pack, auxiliary power receptacle
(see Section 3.3.1) or through the patrol vehicle's cigarette
lighter receptacle. In addition, the Talon has an optional
battery handle which offers complete portability for the traffic
officer.
7.1.1 BATTERY OPERATION
The Talon’s battery handle must be charged prior to usage. An
internal monitor checks the voltage and alerts the operator
should the voltage drop to a minimum operating level. A short
alert tone will be heard and the “BATT” indicator will flash
momentarily. This will repeat every two minutes, but the Talon
will continue to provide speed readings until the voltage drops
below the minimum operating level, when the “BATT” indicator will
be steady and no further speed readings will be possible.
7.1.2 BATTERY CHARGING
Remove the battery handle by turning the unit upside down and
depress the blue handle release button located directly behind
the handle. Slide the handle off the unit and connect the
battery charging cable to the bottom of the handle. The charging
time will vary depending upon the amount of discharge, but
typically overnight will completely charge the Talon’s battery.
22
7.1.3 STATIONARY
1. For stationary operation, select an area that provides a
good View of the traffic to be monitored.
2. Check the immediate area for potential interference sources,
such as large reflecting signs in the direct path of the
radar's microwave beam, power substations and other
potential sources of electrical interference.
3. Position the patrol vehicle in a safe location, with easy
access to the roadway.
NOTE: Cosine effect, angle between the target’s direction of travel
vs. the path to the radar, in the stationary mode, will ALWAYS
be in the driver’s favor. Refer to the National Highway Traffic
Safety Administration's “Basic Training Program in RADAR Speed
Measurement” for speed reduction information due to cosine
angle.
7.1.4 ADJUSTING AUDIO
Adjust the Doppler audio for the desired listening level.
Depress the Audio switch. The Target window will display
“Aud” and the Patrol window will display the current audio
level. This display will remain for approximately two (2)
seconds unless another switch is activated.
With “Aud” displayed, depress either the down arrow (Audio)
or up arrow (Range) to decrement or increment the audio
level. The displays will return to their normal mode two
(2) seconds after the last switch is released.
7.1.5 AUDIO UNSQUELCH
1. To unsquelch the audio, depress the Audio, “Aud” showing in
the Target window, and depress the Mode switch. “Un” will
be displayed, and the audio will be unsquelched. To return
to squelched audio, repeat this step.
2. Set the range control to the desired level. Depress the
Range switch and “rnG” will be displayed, along with the
current level (0-5), Also, the range bar graph will
indicate the current level. The range can be incremented or
decremented by depressing the up arrow (Range) or down arrow
(Audio). The Talon will return to normal operation with the
new range level approximately two (2) seconds after the last
switch activation.
23
Range level 5 is the maximum range, range level 1 reduces
the Talon’s range to its minimum distance, typically 250
feet (90 meters). Some states or departments require a
minimum range level of “0”. The Talon may be ordered with
the minimum set level of “0” instead of “1".
7.2 OPERATION — STATIONARY, HANDHELD
Place the unit in the stationary mode.
Set the range and audio levels as needed.
Complete a tracking history on the target vehicle.
A. Observe the target and surrounding traffic.
B. Estimate the speed of the target vehicle.
C. Point the Talon at the intended target vehicle and pull
the trigger, holding the trigger depressed to complete
the tracking history.
D. Listen to the audio pitch and compare the pitch to the
estimate of speed in B.
E. Observe the speed reading shown on the Talon’s Target
window. It should correspond with B and D above.
Continue tracking the target vehicle as required for
proper target identification.
F. If any of the above elements are incompatible, the
reading must be disregarded.
7.3 STATIONARY TARGET LOCK — HANDHELD
1.
To lock the target speed reading, release the trigger. A
short audio alert tone will be heard in the speaker and the
target speed will be locked and flash in the Lock window.
The Talon will continue to transmit for a period of five (5)
seconds to allow additional tracking of the target vehicle.
when the Target window blanks, or at the end of the five (5)
second time out, the transmitter will return to Hold (non-
transmit) and the target window will blank.
To release a locked speed, pull and release the trigger.
The Lock window will blank. No speeds can be recalled.
24
NOTE: Some models, due to state or local law, require an automatic
unlock feature. The Talon software has a feature that, when enabled,
will unlock all locked speeds when 15 minutes has elapsed.
7.4 STATIONARY FASTEST VEHICLE MODE - HANDHELD
1. If a faster vehicle is observed within the range of the
radar, but due to closer and/or larger targets, would not be
the strongest reflected signal, the operator may place the
Talon in the fastest vehicle mode.
2. while observing traffic, the operator may activate the
fastest vehicle mode by depressing the trigger (transmit
mode), then quickly release and depress, and hold, the
trigger a second time, within % second. As long as the
trigger is held depressed, the Talon will remain in the
fastest vehicle mode.
3. when the trigger is released, and a fastest vehicle is
displayed, an alert tone will be heard, the Lock window will
indicate the fastest vehicle locked speed, the Fast
indicator will be lit and flashing, and the Target window
will continue to track the fastest vehicle until:
A. Five (5) seconds has elapsed.
B. The Target window blanks.
7.5 MOVING MODE — OPPOSITE DIRECTION
1. Remove the handle from the Talon by depressing the handle
release button on the bottom of the main unit.
2. slip the Talon on the mounting pod, pushing rearward until
the release button clicks, indicating the unit is securely
in place.
3. Connect the remote control and speedometer input cables as
required. See Fig. XX.
4. Place the Talon in the moving mode by depressing the Mode
switch, if needed. Both the Target and Patrol windows
indicators will be lit.
5. The Talon may be placed in the Hold mode (non—transmit) by
depressing the Hold switch on the remote control. The Hold
indicator on the rear panel of the Talon will be lit.
25
7.6
While driving, observe traffic and complete a tracking
history as described in Section 7.2 and verify the radar's
patrol speed reading with the patrol vehicle‘s speedometer.
when all elements agree, enforcement action may be taken.
MOVING MODE — TARGET LOCK
1.
If the operator wishes to lock the target speed reading,
depress the Lock switch. A short alert tone will be heard
and the Lock window will display the speed of the target
vehicle.
The Talon will continue to track the target and patrol
speeds.
When the patrol vehicle’s speed has dropped 10 mph (16 km/h)
below the speed when lock was activated, or the Talon is
26
placed in Hold, the patrol vehicle’s speed, at the time of
lock, will be flashing in the Patrol window.
This allows the operator to continue to track the target
while monitoring the patrol vehicle's speed and still retain
the locked patrol speed.
4. The locked speeds may be unlocked by:
A. Depressing the remote's Lock/Release switch.
E. Auto—unlock after 15 minutes, if activated.
C. Changing the mode of operation, moving to stationary.
7.7 MOVING MDDE — PATROL BLANK
l. The operator may blank the flashing locked patrol speed
display by depressing the Patrol Blank switch on the remote
control. Depressing the switch again will return the patrol
display.
7.8 MOVING MODE — FASTEST VEHICLE
1. with the unit operating in the moving mode, observe traffic.
2. Depress and HOLD the Fastest switch on the remote control.
3. The Fast indicator will be lit, the fastest speed will be
displayed in the Fast window and the strongest signal speed
will be displayed in the Target window, and the patrol speed
will continue to track.
7.9 MOVING MDDE — FASTEST VEHICLE LOCK
1. To lock the fastest vehicle speed, momentarily depress the
Lock/Release switch on the remote control.
2. After a short alert tone, the Fast display will indicate
Lock, the Target window will track the fastest speed and the
patrol window will track patrol speed.
3. The Talon will continue to track the speeds as in Section
7.6.
27
7.10 MOVING MODE — SAME DIRECTION
1. Select the moving mode, same direction by depressing the
Opp/Same switch on the remote control. The same indicator
will be lit.
2. While driving, observe traffic traveling the same direction
as the patrol vehicle.
3. Complete a tracking history, and verify the patrol speed
agrees with the speedometer speed reading. Enforcement
action may be taken.
If the patrol speed is 34 mph (54 km/h) or lower, the
maximum difference in speed between the patrol vehicle and
the target vehicle is 25 mph (40 km/h). However, if the
patrol speed is 35 mph (56 km/h) or higher, the maximum
difference speed is 55 mph (88 km/h). The minimum
difference in speed between the patrol vehicle and the
target vehicle is 3 mph (5 km/h).
4. If the target vehicle is traveling slower than the patrol
vehicle, the operator should depress and hold the Slower
switch on the remote control. The Slow indicator will be
lit.
5. when the slower switch is released, it will remain active
for approximately two (2) seconds. This will allow the
operator time to lock the target speed reading.
28
8.0
INFLUENCES AND INTERFERENCE
Interferences from external sources may affect the standard
operation of any radar device, including the Talon. These
influences can be natural or man—made, however the Digital Signal
Processing circuitry will eliminate most of these influences and
a knowledgeable operator should be able to determine the nature
of the influences and their effect, if any, on the performance of
the Talon.
8.1 NATURAL INFLUENCES
1. Heavy rain and blowing dust can cause a scattering
effect which may reduce the effective range of the
Talon. The patrol speed can also be affected by
driving rain. It is recommended that the operator
compare the patrol speed reading and the speedometer
reading frequently during rainy periods,
2. Terrain can affect the range of the Talon. Improper
aiming of the antenna can cause the radar to appear to
have short range. If the target vehicle were on a
slight incline, the antenna could be shooting short of
the intended target vehicle.
3. Strong reflections from roadside objects, such as large
signs, parked cars and buildings can cause double
bounce reflections which are the same as the patrol
speed. These “harmonics” are detected by the DSP,
which inhibits their display. This also occurs if the
intended target vehicle is traveling at the same speed
or a harmonic of the patrol speed.
To notify the operator a harmonic speed was detected,
the Target window will display two (2) dashes (--).
This feature is normally enabled, but may be disabled.
The Target window will be blank if this feature is not
activated.
8.2 MAN—MADE INLUENCES
1. Various reflections can cause most radar to display
incorrect speed readings. These include shadowing,
combined speeds, moving cosine and fan interferences
(splitting speeds).
29
Unlike other radar, the DSP processor in the Talon can
sense and eliminate most of the interferences that
other radar might see as speeds during normal
operation.
Another anomaly of Doppler radar is slow speed
combining when a close target vehicle and the slow
patrol speed combine and are displayed in the Patrol
window. The Talon with speedometer input will
eliminate this effect, and the unit will display the
proper patrol and target speeds.
2. If the power source or internal battery voltage nears
the minimum operating voltage, the Talon will notify
the operator with a short alert tone and flash the
“BATT” indicator for one (1) second. This message will
repeat every two (2) minutes until:
A. The voltage drops below the minimum operating
voltage.
B. The voltage raises above the minimum voltage alert
level.
3. Radio Frequency Interference (RFI) exists when there
are strong RF transmitting stations in the immediate
area of the radar unit, such as the patrol vehicle’s
transmitting radio, high power radio or television
stations. These sources of interference will be
detected by the Talon and the RFI indicator will be lit
and all speed readings will be blanked, except for
locked speeds, until the source of interference is
reduced or eliminated.
Refer to the National Highway Traffic Safety
Administration’s Basic Training Program in RADAR Speed
Measurement, June 1991, for further information on
interferences and training guides.
8.3 GROUNDSPEED
True groundspeed of the patrol vehicle is required by all
moving traffic radar systems before a target vehicle's speed
can be accurately computed. If the Talon loses groundspeed,
due to weak patrol speed returns, the operator may
momentarily place the unit in the Hold mode then activate
the transmitter again to restore groundspeed.
30
If the speedometer input is being used with the Talon, the
DSP will accurately track even a weak patrol speed return
due to the small tracking window, unlike radar without
speedometer input.
The Talon will always look for and display groundspeed
before displaying any targets. The groundspeed radar
signature is unlike any target or interference signal. The
DSP can identify this pattern, which is helpful in
situations such as shadowing or combined speeds. While the
speedometer input and DSP technology will eliminate most of
the influences found in moving radar, it is still the
responsibility of the operator to complete a tracking
history on the target vehicle and verify the patrol speed
with the patrol vehicle’s speedometer. Close observation of
the patrol vehicle's speed reading is recommended to avoid
possible confusion.
The Talon will not display patrol speeds below 10 mph (16 km/h).
Operating moving radar in the rain and snow requires the
operator to pay close attention to the patrol speed. since
rain, fog and snow may affect the ability of the radar
system to find groundspeed, the operator must verify the
displayed patrol speed reading is correct.
31
CARE OF THE TALON
The Talon radar system is designed for long reliable use by law
enforcement agencies. Following basic care guidelines will
ensure the unit gives many years of trouble-free service.
1.
2.
Use a damp cloth to clean the outside of the radar unit
if it becomes dirty. DO NOT use excessive water or any
cleaners or sprays on the outer surface of the Talon's
mounting pod or remote control.
As with all electrical or electronic equipment, protect
from water. While the Talon is a sealed radar unit,
the mounting pod and remote control are not considered
waterproof and if any liquid should get inside, remove
power immediately and send the unit in to a repair
facility. Prompt action can minimize any damage.
If the Talon is used outside in rain or snow, it should
be wiped dry with a clean cloth before ending the
shift.
There are no user serviceable parts in the Talon. The
internal battery handle is protected by an automatic
resettable fuse. The fuse for the mounting pod is
located in the end of the cigarette lighter plug.
Simply unscrew the tip and replace with the same size
fuse.
Do not pick up or carry the Talon by the power or
remote control cable when plugged into the mounting
pod. Broken power and remote control cables are a
common cause of intermittent operation.
If the Talon exhibits decreased range over a period of
time, the unit should be examined by an authorized
service center for possible receiver diode degradation.
Receiver diode degradation has no effect on the unit's
accuracy, but will result in unsatisfactory target
range.
Kustom Signals recommends periodic maintenance of the
Talon radar system. Check with your local service
center and judicial district for requirements.
32
9.1 EQUIPMENT REPAIR/RETURN
should the Talon need repair or calibration from Kustom signals,
Customer Service, the following information is required:
1. Department name, return shipping address and phone
number.
2. Contact name at owning department.
3. Complete description of failure or problem with unit.
Please describe, in detail, what the failure is and
when it is observed. EXAMPLE: In moving mode, targets
are close to patrol vehicle before being displayed.

10.0 CASE LAW
This section is included so radar operates and those individuals
responsible for prosecuting traffic arrests can familiarize
themselves with the more important legal cases involving the use
of traffic radar. To obtain additional information on the
referenced material, consult your community's local law library
or the prosecutor's office.
since the Talon is a Doppler based traffic radar system, some
older case law is presented because of its significance to the
acceptance of the Doppler principles as well as the basic
requirements of the tuning fork test and operator training.
Reference A — State vs. Dantonio (N.J.) 1955 115 A2d35, 49 ALR 2d
460. Landmark case on the acceptance of the Doppler principles
as used in traffic radar.
Reference B — State vs. Shelt (Ohio) 1975 75—D 0—3682, L—75-166.
Establishes that the courts may take judicial notice of the
reliability of moving radar.
Reference C - Honeycutt vs. Commonwealth (Ky) 1966 408 SW 2d 421.
Court establishes that a tuning fork test is an accurate method
of testing the accuracy of a radar unit and along with the Visual
observations of a trained operator, is an accurate means of
determining the speed of vehicles.
Reference D — Krueger, Pantos and Payne vs. State of California
1986 (class action suit - suppression hearing on radar) 887092,
DP44339 and DP54571. Court ruled that a properly built and
tested radar used by a trained operator can accurately determine
the speed of vehicles. The judge dismissed each of the
defendant’s claims that outside influences render the radar
readings inaccurate in the moving mode of operation. He ruled
that proper classroom and field training enables an officer to
avoid any false or inaccurate readings due to outside influences.
The court held and took judicial notice of the accuracy of
Doppler radar in both the stationary and moving modes of
operation.
Reference E — Samuel Knight vs State of New York Superior Court.
72 N.Y. 2d 481, 530 N.E. 2d 1273 (1988). The court ruled that a
trained operator, who properly tested the radar, observed the
traffic and checked the patrol speed against the patrol vehicle’s
speedometer, can accurately determine the speed of vehicles while
the patrol vehicle is moving. The court affirmed the lower
court's ruling and accepted judicial notice of the radar in the
moving mode of operation.
34
11.0 FCC — TRANSMITTER RULES AMENDED
The Federal Communications Commission (FCC) has amended its rules
to eliminate the required annual measurement of transmitter
power, frequency and modulation and to specify transmitter power
in terms of output power for licensees in the Public Safety,
Industrial and Land Transportation Radio Services. The action
was the result of a rule making procedure initiated October 29,
1976, on the request of HTaB Electronics.
Under the rules, which amend Part 89, 91 and 93, licensees are
required to operate their transmitters within the specified
technical parameters.
Each licensee must take effective measures to ensure the
integrity of his communications system, including periodic
evaluation of receiver performance in order that undue air time
not be consumed in repeating messages lost through poor effective
receiver sensitivity, the FCC said.
For the sake of convenience and simplicity of transmitter power
measurement, the FCC specified that in the future, transmitter
output power, rather than the direct current input power to the
final radio frequency stage, be the standard parameter used to
indicate transmitter power. The FCC defined transmitter output
power as that power measured at the transmitter output terminals
when connected to a load of the impedance recommended by the
equipment manufacturer.
11.1 FCC — RADAR UNIT LICENSING AMENDED (PART 90)
The Commission has eliminated the requirement for local
governmental entities licensed in the Public Safety Radio
services to obtain a separate authorization for radar speed
detection devices.
This change reduces paperwork for the Commission’s licensing
staff and for police and other local government units, which no
longer have to apply for new radar authorizations or modify or
renew existing licenses and may operate speed detection devices
as part of their base/mobile communications systems.
To provide the Commission with a record of such units in use, the
licensees are required to list the number of speed detection
units and the frequencies on which they operate at the time of
renewal of their land mobile authorization. Ordinarily, this
would be once every five years and would not be a significant
addition to the renewal process, the Commission noted.
This action became effective February 1, 1933.
35
If the owning department does not hold a Public Safety Radio
license, but is dispatched by another agency, the owning
department will need to obtain a Public Safety Radio license from
the FCC. Filing FCC form 574 and obtaining a separate license
will be required before placing the radar into service.
35
