5. Basic Operation
The following sections give an overview of the basic operation of
the DragonEye Compact LIDAR for normal speed measurement
applications. Be sure to review the "Recommended System Checks"
section to understand the suggested daily performance checks and
periodic certications. Additional details of special features and other
operation modes are in the "Advanced Controls and Modes" sections.
5.1 Battery Installation
Lift the rubber battery cover
from the lower corners and
remove the old batteries.
Figure 5.1
Battery Installation
Insert two "AA" cell
batteries, positive end
against the at contacts
and negative ends against
the spring contacts. Replace
the rubber batter cover and
press the snap in place.
The DragonEye Compact LIDAR is
designed to use quality alkaline
"AA" cells from brand name manufacturers.
The device also functions with rechargeable NiMH
"AA" cells commonly available at consumer stores.
• The LIDAR's rubber battery cover forms part of the
water resistant enclosure protecting the unit from rain
and moisture. Please be sure to change batteries in a
dry environment.
5.2 Powering On
When fresh batteries are installed, the unit will automatically power
up, run through Self Test and be ready for use.
DragonEye Compact User’s Manual
17
• If the LIDAR is inactive for approximately 30 seconds,
it will automatically transition into sleep mode to
conserve battery life. If this happens, simply click the
re trigger again to wake up the unit.
5.3 Selecting Speed Mode
The LIDAR will normally power up in "Speed" mode, unless it was
recently used in a dierent mode. If "Speed" mode is not displayed
on power up, simply press until the side panel displays:
MPH
FT

5.4 Using the HUD Sighting System
The Head-Up display provides a precision aiming reticle, speed
reading, and other status information. To nd the sighting reticle,
press and release the trigger to wake up the LIDAR and look directly
through the HUD letting your eyes focus on a target well in front of
the LIDAR unit. If you haven't used a HUD device before, it might take
a minute or two for your eyes to adjust the rst time.
Figure 5.4
HUD aiming
DragonEye Compact User’s Manual

• Make sure the LIDAR's brightness setting is on medium
or high if working in daylight.).
The LIDAR's laser beam is invisible, but will be contained within the
aiming reticle. This is your aim point for target vehicles.
5.5 Roadside Setup
When rst learning to use the DragonEye Compact LIDAR, it is best to
select a straight stretch of roadway with a line of sight of 500 ft
(150 m) or more.
Approaching or receding vehicles should be targeted such that your
line of sight through the HUD is as parallel as possible to the path of
the target vehicle. This will minimize the "cosine eect" as described
in Chapter 10 of this manual.
• The cosine eect applies to both RADAR and LIDAR
systems and always results in a slightly lower than
actual reading..
A good rule of thumb for approximately straight roadways is to
target a vehicle at a range which is at least ten times the operator's
perpendicular distance to the vehicle's lane of travel. For example,
if the operator is 30 feet (9 m) from the vehicle's lane of travel, the
vehicle should be targeted at 300 feet (90 m), or greater. This would
result in a measured speed reading which was approximately 0.5%
less than actual.
5.6 Measuring Vehicle Speeds
For approaching targets, aim the LIDAR's reticle at the front grill or
front license plate of the vehicle. Good targets for receding vehicles
are the license plate or tail lights. Use the boundaries of the reticle
pattern to ensure only the intended vehicle is being targeted.
Squeeze and hold the laser re trigger while maintaining your aim.
DragonEye Compact User’s Manual
19
You may hear an intermittent audible tone as the LIDAR searches
for a valid target signal. You will also see "----" displayed in the HUD
indicating the laser is ring and a reading is being acquired. Once
target vehicle data is identied, the LIDAR will product a continuous
lower frequency tone. When the data from the vehicle reaches an
acceptable accuracy level, audible tone will switch to a continuous,
higher frequency and the vehicle speed reading will be displayed in
the HUD and on the side panel.
• At typical distances the acquisition sequence can
happen very quickly and you may simply hear the high
frequency tone and see the speed display immediately.
A positive speed reading will be shown for an approaching vehicle,
while receding vehicles are indicated with a negative reading. (Both
the HUD and the back panel will show a "-" sign for receding vehicles.)
The DragonEye Compact LIDAR will continuously update the target's
speed reading at an approximate rate of 3 times-per-second as long
as the trigger is depressed and the data quality is acceptable. While
not required, it is recommended to track the vehicle for at least 1
second to establish robust condence in the speed reading.
5.7 Speed Display Lock
Once a desired speed reading is acquired, the operator can "lock" the
speed reading on the side panel display by simply releasing the laser
re rigger. If a speed reading is lost after tracking a vehicle, the last
speed reading will ash for approximately two seconds, giving the
operator an opportunity to lock in the vehicle's speed. (The ashing
speed reading will be immediately over written if the operator acquires a
new speed reading.)
5.8 Speed Display Lock Retention
Once a speed is locked into the side display, it will be retained there
for up to 20 minutes. If the laser re trigger is depressed within 30
seconds after the speed is locked, the display will clear and prepare
for a new reading. If no buttons are pressed for 30 seconds after the
DragonEye Compact User’s Manual
20
speed reading is locked, the unit will go into a sleep mode, turning
o the HUD and displaying "Power-Save" on the side panel along
with the locked reading. In the Power-Save state, a rst laser trigger
press and release will "wake" the LIDAR but retain the locked reading.
A second trigger press will then clear the reading. This feature is
intended to aid in preventing the operator from accidentally clearing
the locked reading.
5.9 Range Mode
The LIDAR system can be used to measure distances to a variety of
targets. To enter Range Mode, press the Mode Button until the
side panels displays:
FT
Figure 5.9
Side Panel indicating Range Mode active
Use the aiming reticle in the HUD to select your desired target.
Squeeze and hold the trigger down until a range reading is displayed
in the HUD and on the side panel display. The trigger may be
continuously held down as the unit is moved from target to target
for quickly checking multiple ranges. The last range reading in the
display is locked when the trigger is released. Range readings are
displayed in tenths of a foot on the side panel and in the HUD up to
999.9 feet (or 999.9 m). Above this, range readings are displayed to
the nearest integer foot or meter.
The maximum target distance is 3000 feet (914 m) which can be
obtained from highly reective surfaces such as retro-reective road
signs or vehicle tail lights/license plates. The range to non-retroreective targets will vary depending upon their infrared reectivity.
Typical ranges are >1000 feet (305 m) from a tree with green foliage,
>1500 feet (457 m) to a white concrete building and 1000 feet (305
m) from a very black, non-reective target. The minimum range (in
"Normal" Weather Mode) is 10 feet (3 m) when in Range Mode and 50
feet (15 m) when in Speed Mode.

6. Advanced Controls and Modes
6.1 Self Test Initiation
Press to enter the system menu options. "Self Test" is displayed
as the rst menu option. Press to initiate the Self Test sequence.
All critical internal timing electronics and software components are
checked. Also, all display components are illuminated to allow the
user to verify proper operation. A pass or fail indication is given at
the end of the self-test. A "pass" indication then returns the operator
to the current mode of operation, while a "fail" indication will halt
operation indicating the need for service.
6.2 Weather Modes
Press the button, and then use the up/down arrows
to select "Weather". Press Enter to select "Weather" then use the
up/down arrows to select "Normal" or "Poor". Press the Enter button
to conrm your choice and exit back to your current mode of
operation. The weather modes function as described below:
6.2.1 Normal Weather Mode
In Normal Mode, the LIDAR has no additional restrictions placed
upon the minimum distance at which a target can be acquired
(besides the normal minimum range specication). If rain, snow,
fog or other obstacles are present in the line of sight to the target,
it is possible the LIDAR will receive signals from these objects
preventing a reading from being displayed on the targeted vehicle.
6.2.2 Poor Weather Mode
Select Poor Weather Mode to improve the LIDAR's ability to shoot
through rain, snow, fog, or other airborne particulates such as
heavy dust or sand. The Weather indicator will be displayed in
both the HUD and the side panel display.
In Weather mode, the LIDAR will not acquire any targets within
250 ft (76 m). However, due to its smart target-lock capability, the
LIDAR will continue to track oncoming cars inside the 250 ft limit,
provided they were initially acquired outside of this range.
DragonEye Compact User’s Manual
22
6.3 Minimum and Maximum Ranges (Range Window)
While in Speed mode, the Minimum and Maximum Range settings
are used to set limits (or a range window) outside of which, speed
readings will not be displayed.
To adjust either of these settings, press the Menu button and
then use the up/down arrows to display "Minimum Range"
or "Maximum Range". Press the Enter button to select. The
display will give you the option to use the up/down arrows to set the
range or 'shoot object' to use the LIDAR's range function to set the
range limit. To manually set the range, simply use the up/down arrow
buttons to set the desired limiting distance. If the arrow buttons are
held down, the units will change in larger increments after about
10 seconds. When the desired range value is in the display, press
the Enter button to accept. Note, once the operator begins to
use the up/down arrow buttons to set the range limit, the "shoot"
option will no longer be available. Alternatively, the Minimum and/
or Maximum range values may be set by "shooting" a target that
represents the particular range limit (such as a school zone or work
zone sign). To shoot the Minimum or Maximum range, enter the
desired menu and instead of using the up/down arrows, pull and
hold in the LIDAR trigger and aim at the target that represents the
Minimum or Maximum range. You may range to the target multiple
times until you are positive the correct target has been selected.
Press the Enter button to conrm the value. Once the Minimum
and/or Maximum range values are set, the LIDAR will display only
speeds between these values. If a vehicle is acquired outside of this
range window, a target acquired audible tone will be heard but
dashes (- - - -) will be displayed in the HUD and on the side display
in the speed reading area. Also the word "window" will be displayed
to indicate the target was acquired outside of the allowable range
window. To quickly remove the Range Window settings, use the
Menu button, then use the arrow buttons to select "Load Defaults".
Press the Enter button to reset all user settings to default values.
DragonEye Compact User’s Manual

• The adjustable Maximum Range Menu may not be
available on some units where jurisdictions may x the
maximum range allowed for the LIDAR devices.
6.4 Direction Filter
The DragonEye Compact LIDAR allows the user to set the system to
display speeds on:
1) Only approaching vehicles
2) Only receding vehicles
3. Both approaching and receding vehicles
The default value is set for both approaching and receding vehicles.
To set the Direction Filter, press the Menu button then use the
up/down arrows until "Direction Filter" is displayed on the
side panel. Press the Enter button and then use the up/down
arrows to display the desired lter setting: APPROACH, RECEDE, or
BOTH. Press Enter to accept the setting.
The LIDAR will return to the current operating mode (range or
speed).
• If a vehicle is targeted in a direction opposite that of
the Filter selection, the LIDAR will still output the solid
audible tone, however the HUD and side panel will
show "- - - -" in the speed display area. The side panel
will also display the indication "Approach" or "Recede"
to indicate that a vehicle has been targeted traveling in
a direction opposite to that of the Filter.
6.5 Dierential Distance Test
The Dierential Distance Test is an optional accuracy check preferred by
some jurisdictions. It is not a manufacturer required test for daily system
checks. This function provides a slightly dierent test for LIDAR Units set
up in English versus Metric units, so please review carefully.
DragonEye Compact User’s Manual
24
6.5.1 Dierential Distance: LIDAR in English Units (MPH)
The (MPH) Dierential Distances Test uses two xed targets
separated by a precisely known distance. Using the LIDAR's range
function to determine the separation between the targets, coupled
with the internal acquisition period of the LIDAR's speed mode, the
test provides a simulated speed reading (in MPH) which should be
double the target separation measured in feet.
Use two at targets, approximately 2 ft x 2 ft square, painted at
white. Place the targets at precise distances from a "zero" point
where the LIDAR will be positioned. The targets should be set
at integer feet values from the LIDAR zero point and should be
approximately 25 ft apart. Recommended target distances are
50.0 ft and 75.0 ft from the LIDAR unit. Ensure the front end of the
LIDAR unit is positioned exactly at the zero point, using a tripod if
necessary.
On the LIDAR unit, press the Menu button then use the up/
down arrows until "Di Distance" is displayed. Press Enter .
Carefully obtain a range reading from the rst target and then
press Enter . Carefully obtain a range reading from the second
target and then press Enter . The LIDAR will then display the
simulated speed on the rear display. The speed reading should be
within +/-1 MPH or twice the range separation as measured in feet.
For example, using the target distances of 50.0 and 75.0 ft, the
simulated speed reading should be 2 x 25.0 = 50 MPH +/-1 MPH.
So a simulated reading of 49, 50, or 51 would pass the test. Press
Menu to exit the Dierential Distance Test and return to the
normal operating mode.
If the LIDAR does not pass the test, carefully recheck the distances
and reposition the targets and LIDAR if necessary then repeat the
test. If the unit continues to fail the test, please contact customer
service.
DragonEye Compact User’s Manual
25
6.5.2 Dierential Distance: LIDAR in Metric Units (KPH)
The (KPH) Dierential Distance Test uses two xed targets
separated by a precisely known distance. Using the LIDAR's range
function to determine the separation between the targets, the
KPH Dierential Distance test provides a quick check of the LIDAR's
ability to measure the distance between two targets.
Use two at targets approximately 0.5 m x 0.5 m square, painted
at white. Place the targets at precise distances from a "zero"
point where the LIDAR will be positioned. The targets should be
set at integer feet values from the LIDAR zero point and should
be approximately 10m apart. Recommended target distances are
20.0 m and 30.0 m from the LIDAR unit. Ensure the front end of the
LIDAR unit is positioned exactly at the zero point, using a tripod if
necessary.
On the LIDAR unit, press the Menu button then use the up/
down arrows until "Di Distance" is displayed. Press Enter .
Carefully obtain a range reading from the rst target and then
press Enter . Carefully obtain a range reading from the second
target and then press Enter . The LIDAR will then display the
simulated speed on the rear display. The distance should be within
0.5 m of the actual distance between the targets.
If the LIDAR does not pass the test, carefully recheck the distances
and reposition the targets and LIDAR if necessary then repeat the
test. If the unit continues to fail the test, please contact customer
service.
6.6 Timed Distance Mode
The Timed Distance Mode allows the LIDAR unit to be used to
determine a vehicle's average speed over a known distance between
two visible reference objects along a roadway.
To enter the Timed Distance Mode, press Menu and then use
the up/down arrows to display "Timed Distance" on the
rear display. Press Enter . The side panel will display:
DragonEye Compact User’s Manual
26
Timed Distance
200
or
Shoot Object
Figure 6.6
Side Panel indicating Timed Distance Mode active
The operator may now enter the reference distance in feet (meters)
between the two reference objects using the up/down arrows
. Alternatively, the operator may shoot the two reference points
to determine the distance to be traveled.
• The reference distance must be at least 200 feet (60
meters).
• If the operator elects to shoot the distance to the
reference objects, please ensure both reference points
are on one side of the operator and in a straight line
with the operator's position. The LIDAR will subtract
the two readings to determine the distance.
To shoot the distances, simply aim at the longer range reference
object rst and pull the trigger to obtain a distance reading. Release
the trigger to lock in the distance reading. If you are not satised
with the reading, you may simply aim and shoot the rst reference
object again. Once you are satised with the reading, press Enter
. The unit will prompt you to shoot the second reference object.
If the second reference object is located where you are standing
with the LIDAR, simply press Enter . Otherwise shoot the second
reference object and press Enter when satised with the distance
reading. The unit will show the distance between the reference
objects.
DragonEye Compact User’s Manual
27
At this point you have either entered the reference distance or
determined it by shooting the reference objects. If the reference
distance is acceptable, press Enter . Otherwise press the Menu
button to "escape" from the menu system.
Once the reference distance is accepted, the side display will show
the reference distance and instructions to "Click Trigger to Start". Click
the trigger when a vehicle crosses the rst reference object point to
start the timer. Click the trigger a second time to stop the timer. The
unit will display the average speed of the vehicle on the side panel.
To measure the average speed of additional vehicles, simply click the
trigger once to clear the old reading and the timer is now re-armed
for a new reading.
6.7 Load Defaults
The factory default settings for the LIDAR can be restored at any time
by pressing then selecting "Load Defaults" using the up/down
arrows and pressing Enter . This command restores
default brightness and audio levels as well as settings for Minimum
and Maximum range values.
6.8 ECCM Control
The ECCM menu allows the operator to temporarily disable the
LIDAR's Electronic Counter-Counter Measure (anti-jamming) system.
To activate or disable the ECCM, press then use the up/down
arrows to select "ECCM" and press . Then use the
up/down arrows to select "Active" or "Disabled" and press to
conrm your selection. If ECCM is disabled, the LIDAR unit will return
to ECCM "Active" if it is not in use for a few hours, if the batteries are
replaced, or if "Load Defaults" is selected.
• While the DragonEye Compact is fully functional with
ECCM set to "Disabled", the ECCM setting should be left
in the "Active" state during normal operation to give
the full protection against laser detectors and jammers.
DragonEye Compact User’s Manual
28
6.9 Input / Output Port
A mini USB style connector is located on the bottom of the unit. This
connector can be used to collect speed and range measurement
data during operation using a standard cable and custom software.
Contact Decatur Electronics at 800.428.4315 for further details
regarding use of the I/O port.
7. Recommended System Checks
The DragonEye Compact LIDAR system is designed to provide years
of service with limited maintenance. The unit uses sophisticated
digitally locked electronics to ensure continued accuracy. However
we recommend performing the following system checks before each
shift to ensure condence in the instrument:
7.1 Self Test
Press to enter the system menu options. "Self Test" is displayed
as the rst menu option. Press to initiate the Self Test sequence.
All critical internal timing electronics and software components are
checked. Also, all display components are illuminated to allow the
user to verify proper operation. A pass or fail indication is given at
the end of the self-test. A "pass" indication then returns the operator
to the current mode of operation, while a "fail" indiction will halt
operation indicating the need for service.
If the LIDAR is unused for an extended period of time (approximately
an hour), the Self Test routine will run upon the wake-up trigger pull.
7.2 Alignment Test
Verify the alignment of the HUD aiming reticle by selecting a target
with straight boundaries such as a telephone pole or road sign at a
distance of >100 feet (30 meters). Set the unit to Range Mode. While
holding the trigger in, slowly pan the aim point on and o the target
edge, verifying the range reading in the HUD changes as the reticle
passes onto the target. The preceding veries horizontal alignment.
Rotate the unit 90º onto its side while continuing to look through the
HUD and repeat the above test to verify vertical alignment.
DragonEye Compact User’s Manual
29
7.3 Fixed Target Distance
The DragonEye Compact LIDAR uses time of ight laser distance
measurement as its core technology in determining vehicle speed.
Therefore a quick check of the unit's ranging accuracy is suitable
for daily condence checks. Locate a at target, at a known range
between 50 and 200 feet (15 and 60 meters).
• The target distance should be carefully conrmed with
a steel tape measure or professional survey device.
Ensure the front of the LIDAR unit is at the zero point, and carefully
obtain range readings from the target. Verify the readings are within
+/- 1 foot (+/- 0.3 meters) of the actual range. If the unit does not
pass both of the above testes, carefully check your setup and perform
the test again. If the unit still does not pass, please contact your
specied service representative.
7.4 Certication
The manufacturer suggests that your LIDAR unit be returned (or sent
to an authorized testing laboratory) periodically for certication. The
certication process will provide detailed checks on alignment and
mechanical integrity as well as verication testing against controlled
speeds from 5 to 200 MPH (8 to 321 KPH).
8. Care, Cleaning, and Storage
Your DragonEye Compact LIDAR is designed to keep performing with
very little user maintenance. Besides replacing the batteries there are
no user serviceable parts and the unit should NOT be disassembled.
8.1 Guidelines
• Avoid spilling food, beverages and other liquids on the device.
• When you are not using or transporting the device, store it in its
original packaging.
• When storing the LIDAR in holsters or other containers used
on motorbikes or vehicles, do not hard mount the LIDAR to the
container; instead use a cushioned container. Hard mounting to
DragonEye Compact User’s Manual
30
vehicle frames can couple excessive vibration into the LIDAR unit
resulting in damage to internal components.
• Store the unit in a cool dry place when possible.
• Avoid temperature extremes beyond -22ºF (-30ºC) and 140ºF
(60ºC). Avoid leaving the unit in excessively hot or cold areas
such as the dashboard of a car in summer or in the trunk on
extremely cold nights.
• Periodic cleaning of the front lenses or HUD glass is only
necessary if they acquire signicant dirt or other debris
that limits optical transmission. If cleaning is necessary, use
compressed air or a soft brush to remove loose debris st.
• To clean the optics, the glass surfaces should be cleaned with
water and a soft cloth or tissue. Isopropyl Alcohol (rubbing
alcohol) can be used if needed. Wipe from the center of the lens
outward in a spiral motion.
• The HUD glass may be cleaned with a cotton swab to facilitate
reaching the surfaces. If you encounter a stain or speck that cannot
be removed with gentle pressure, do not increase the cleaning
pressure as this may damage the lens coatings. Small scratches
and stains during the lifetime of a unit are normal and will not
noticeable aect the performance of the LIDAR.
• When cleaning the main body of the LIDAR use a soft clean cloth
and a mild soap and water solution. Do not use harsh cleansers
such as acetone (nail polish remover), ammonia, or other strong
cleaning solutions as these may damage the polymer housing
materials.
8.2 General Handling
The DragonEye Compact LIDAR is built to be rugged and endure
many types of accident impacts and drops. However, please
remember that much like a camera, the LIDAR is a precision optical
instrument that should be handled with reasonable care. Avoid
dropping or throwing the unit into the patrol car as hard surfaces can
scratch or break the glass components.

10. Cosine Effect
The term "Cosine Eect" as typically used in law enforcement speed
measurement refers to the reduction of a vehicle's measured speed
using Radar or Laser systems as compared to the actual vehicle
speed, when targeting the vehicle at an angle. The diagram below
shows the line "V" as the vehicle's travel direction and the LIDAR
operator's line of sight "O" to the target Vehicle. The angle between
these two lines is labeled theta "Θ". Motion of the vehicle along "Line
V" is projected onto the LIDAR operator's line of sight "Line O". Using
standard trigonometry, this projected motion can be show to be:
ΔΟ = ΔV x COSΘ
