Critical Warning”, you may be able to restart the LIDAR and gain
usable time by switching the brightness and volume to the lowest
acceptable levels.
Jam / ECM Attempt Indication
The DragonEye Compact Speed LIDARTM contains sophisticated
counter measures to defeat LIDAR “Jamming” devices available in
the consumer market place, while continuing to display accurate
speed calculations. The system also indicates when a jammer or
other Electronic Counter Measure (ECM) is detected on the target
vehicle by displaying the phrase “Jam ECM” on the side display and
flashing the “” symbol in the HUD. Note that extremely bright
surfaces on the target vehicle, such as high beam headlights or sun
reflections can cause the jam indicators to turn on. If you experience
any difficulty locking in a speed reading when “Jam” is indicated, try
moving the HUD aiming point to another location on the vehicle.
Basic Operation
The following sections give an overview of the basic operation of the
DragonEye Compact Speed LIDARTM for normal speed measurement
applications. Be sure to review the “Recommended System Checks”
section to understand the suggested daily performance checks and

Battery Installation
Lift the rubber battery cover
from the lower corners and
remove the old batteries using
the pull ribbon.
Insert two “AA” cell batteries on
top of the pull ribbon, with
positive end against the flat
contacts and negative end
against the spring contacts.
Replace the rubber battery cover and ensure a good seal along the
tongue and groove interface.
Note: The DragonEye Compact Speed LIDARTM 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.
Caution: 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.
Powering On
When fresh batteries are installed, the unit will automatically power
up, run through Self Test and be ready for use. (Note: 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 fire trigger again to wake up the unit.)

DragonEye Technology, LLC |Doc. 30666 Rev. 03
Selecting Speed Mode
The LIDAR will normally power up in “Speed” mode, unless it was
recently used in a different mode. If “Speed” mode is not displayed
on power up, simply press until the side panel displays:
Using the HUD Sighting System
The Head-Up display provides a precision aiming reticle, speed
reading, and other status information. To find 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 first time.
(Note: 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
split oval aiming reticle. This is your aim point for target vehicles.

Your Lidar may include a user selectable Menu option to use a red
“Dot” reticle instead of the split oval. When selected in the Menu
system, the Dot reticle HUD view will look similar to the illustration
below:
Roadside Setup
When first learning to use the DragonEye Compact Speed LIDARTM, it
is best to select a straight stretch of roadway with a line of sight of
150 metres 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 effect” as described
in Appendix A of this manual. (Note: The cosine effect 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 vehicles lane
of travel. For example, if the operator is 9 metres from the vehicle’s
lane of travel, the vehicle should be targeted at 90metres, or greater.
This would result in a measured speed reading which was
approximately 0.5% less than actual.

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 fire trigger while maintaining your aim.
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 firing and a reading is being acquired. Once
target vehicle data is identified, the LIDAR will produce 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.
Note: At typical distances the above 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. (Note:
Both the HUD and the side panel will show a “-“ sign for receding
vehicles.)
The DragonEye Compact Speed LIDARTM 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 confidence in the speed reading.

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 fire trigger. If a speed reading is lost after tracking a vehicle,
the last speed reading will flash for approximately two seconds,
giving the operator an opportunity to lock in the vehicle’s speed.
Note: The flashing speed reading will be immediately over written if
the operator acquires a new speed reading.
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 fire trigger is pressed 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
speed reading is locked, the unit will go into a sleep mode, turning
off the HUD and displaying “Power-Save” on the side panel along
with the locked reading. In the Power-Save state, a first 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.
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:
MODE
ENTER

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 metres. Above this, range readings are displayed to the
nearest integer foot or meter.
The maximum target distance is approximately 914 metres which
can be obtained from highly reflective surfaces such as retro-
reflective road signs or vehicle tail lights/license plates. The range to
non-retro-reflective targets will vary depending upon their infrared
reflectivity. Typical ranges are >305 metres from a tree with green
foliage, >457 metres to a white concrete building. The minimum
range (in “Normal” Weather Mode) is 3 metres when in Range Mode
and 15 metres when in Speed Mode
