STATIONARY

DOPPLER RADAR

INITIAL SETUP

– Remove the battery cover from the back of

the Trafc Advisor™. Insert the batteries in the

direction indicated by the polarity marks inside

the battery compartment and replace the cover.

– Remove the clear plastic sticker that covers the

orange button and display on the front of the

unit and the yellow sticker from the back of the

unit.

RECALL READINGS

– To recall up to the last 10 measurements,

simply TAP the black RECALL button. Each

time the button is tapped, it will display the

previously recorded speed, most recent rst. A

single dash “-” indicates that you have reached

the end of the list.

AUTOMATIC SHUT-OFF

– The Trafc Advisor™ continues to display the last

speed until the button is tapped again or it will

automatically turn itself off after 30 seconds

of inactivity.

VERTICAL IS CRITICAL

– The Trafc Advisor™makes a measurement by

sending out very low power radio waves and

looking for them to bounce off a moving object.

These radio waves are focused in a small cone

shaped like a ashlight beam which comes out

of the raised square on the back of the Trafc

Advisor™(the radar lens).

– Hold the Trafc Advisor™straight up and down

vertically like a camera phone with the radar

beam pointing in-line with the path of the

moving object.

– If you tilt the Trafc Advisor™down, the beam

may end up pointing into the ground and

missing the moving object.

– Do not block the radar lens.

WATCH YOUR ANGLES

– All Doppler speed radar technology measures objects moving in-line with the radar beam, not

perpendicular. To get the most accurate readings, make sure the path of motion is within the narrow radar

beam cone (about the shape of a focused ashlight beam). Tilting the Trafc Advisor™ too far up or down

may also cause the beam to miss the moving object.

TOP VIEWSIDE VIEW

INSTANT ON

– The Trafc Advisor™will turn itself on and begin

the measurement sequence as soon as you “tap”

(quickly press and release) the ORANGE button.

– When the Trafc Advisor™ senses a moving object

it will display the speed. If it does not nd anything

it will display “---”

– There is no need to clear the display before

making a new measurement. If you tap the button

again the display will be updated with the new

reading.

2. IMPORTANT REMINDER

The Trafc Advisor™ radar is designed for accurate trafc survey work in

trafc engineering, safety and calming programs. It is certied accurate

by the International Association of Chiefs of Police (IACP) designated radar

test lab. However, it does not have all the features recommended for Law

Enforcement use. The Trafc Advisor™ radar is NOT intended for Judicial

Speed Enforcement applications.

How to Avoid the COSINE Error

RADAR MEASUREMENT

USING TRAFFIC ADVISOR™

•TheTrafcAdvisor™is a stationary mode radar and is not

intended to be used in a moving vehicle.

•TheTrafcAdvisor™radar tracks the strongest signal. It

displays the speed of the vehicle with the strongest radar

return, which is typically the closest vehicle.

•TheTrafcAdvisor™measures vehicles that are approaching

and receding from the stationary radar position. It does not

discriminate the direction of the moving vehicle.

BUTTON

OPERATION

•QuicklyTAP(pressandrelease)

the ORANGE button to take a single

measurement snapshot of a vehicle speed.

The displayed speed will remain visible for

30 seconds.

•PressandHOLDtheORANGEbutton

to continuously measure the changing

speed of a vehicle as it accelerates or

decelerates. The Trafc Advisor™ radar will

updatethedisplayedspeedapproximately

every3/4ofasecondaslongasyou

continue to HOLD the ORANGE button

down.

•TAPthesmallblackRECALLbuttonto

review the tracking history of the previous

10 recorded speeds.

Due to the nature of how Doppler speed radar works, all speed radars will only measure the

relative speed of a target in the direction that it approaches or moves away from the speed

radar. The Traffic Advisor™will measure speed most accurately when the path of the moving

target runs directly in-line with the beam of the radar. (Note: Always be safe. Never put

yourself in a position where you could be struck by a moving object.) If you point the beam

of the Traffic Advisor™at an angle different than the path of the moving object, you will

measure a slower speed than the object actually travels along its path. You may also find it

more dif ficult to capture a small object within the narrow beam of the radar when you

measure off angle. (Think of the beam like a focused flashlight beam, not like a floodlight).

This off angle speed measurement error is

referred to as the COSINE error, named after the mathematical function that allows

youtocalculatetheexactspeedversusangle.Themeasuredspeedwillalwaysread

lower than the actual speed as you move off the centerline of the path of the moving

object. For small angles, this error will be very small. The chart above right shows the

percentage error for a given angle between the radar beam and the moving object.

STEP ONE

To change the units of

measurement, press both

buttons at the same time,

and then let go. The

currently selected units

indicator will blink.

STEP TWO

Press the ORANGE

button repeatedly until you

have selected the desired

units.

STEP THREE

Press the RECALL button

to save the selected

units and return to

normal operation.

CAR

FROM 1/2 MILE (0.8 KILOMETERS)

MOTORCYCLE

FROM 1/4 MILE (0.4 KILOMETERS)

Radar technology works by sending a signal out to an

object, and then measuring the reected signal that

bounces back. The larger the object, the greater the

reected signal and therefore the longer the range.

The Trafc Advisor™ will accurately measure the speed

10. VERIFYING THE RADAR ACCURACY

Tuning Fork Test

The tuning fork is calibrated to vibrate at a specific frequency that is picked up by

the radar as a precise speed reading. Tap the tines gently on a solid, non-metallic

surface. Then hold the vibrating tuning fork with the narrow side facing the back of

the radar, a few inches away. Tap the button to read the speed. Be sure not to move

the tuning fork or radar during the measurement. If the speed reading is within ±1

MPH or ±2 KPH of the speed stamped on the fork, the radar gun is working properly.

NOTE: Tapping the tines against very hard surfaces like concrete or metal

can possibly damage the tines. Be sure to only tap the tuning fork against

materials that are softer than metal, such as wood or hard plastic.

Tap tuning fork against solid surface

Position vibrating tuning fork behind radar as

shown here and tap the button to read the speed

7. SOURCES OF INTERFERENCE

Mechanical and Electrical

Before taking radar speed measurements, always start by making a visual tracking

history of the vehicle. All Doppler radar speed measurements need to be considered in

thecontextofthetotaloperatingenvironment.Thiscanincludebothmechanicaland

electrical sources of interference. Sometimes this interference can create unintentional

readings, or so-called “ghost” readings. With a visual tracking history, these are

readily identifiable as such in the presence of a valid target. These unintentional

readings will disappear and be replaced by the target reading when the target vehicle

gets close enough and will not affect the accuracy of the actual target reading.

MECHANICAL

Any objects that rotate, move or vibrate can create

a reading on a Doppler speed radar. Large amounts

of vibration, such as ver y loud noises, can also

result in readings. Things like motors, fans, or

other motion can be detected by the speed radar.

Aiming the radar beam away from the motion will

eliminate the interference. In some cases, if you are

measuring the speed of a vehicle at a very close

distance, you may pick up the engine, the radiator

fan,theheaterorA/Cfaninsidethecar,moving

wheels or hubcaps, etc. In this case, tr y to make

the measurement from a further distance away. You

mayalsoexperiencethistypeofinterferencewhen

you are trying to measure speeds from inside a car

with the engine running, as you may measure the

speedoftheinternalfansandnottheexternal

moving objects.

ELECTRICAL

Cell phones, wireless devices,

radioandT Vtransmitters,

computers, fluorescent lights,

televisions, walkie-talkies, etc.,

can also possibly create

unintentional readings.
