1.0 SYSTEM DESCRIPTION
1.1 The battery powered or USB powered, laser based speed measuring lidar system is a single-
piece design, consisting of the laser optics, aiming Heads-Up-Display (HUD), speed and range
displays and counting and control circuitry.
1.2 The unit meets all requirements of the International Association of Chiefs of Polices (IACP) Lidar
Performances Standards as defined in “SPEED-MEASURING DEVICE PERFORMANCE
SPSPECIFICATIONS: LIDAR MODULE” and is listed on the current IACP Consumer Products
List (CPL).
1.3 The unit is rated Class I eye safe. The laser system is designed to operate at a wavelength of 904
nanometers, +10 nm.
1.4 The unit operates within its specifications at ambient temperatures from –22F to +140F (-30C
to +60C).
1.5 The unit is waterproof to IP 67 and NEMA 6 rating.
1.6 The unit is capable of accurately determining target vehicle speeds with an accuracy of +1/-2
mph (+2/-3 km/h). The unit measures speeds in a range from 10 to 200 mph (16 to 320 km/h).
1.7 The speed processing circuit of the unit utilizes scientifically accepted “time of flight” principles,
including software for filtering out of boundary data, least squares averaging and time/distance
calculations to determine the average speed of the target vehicle.
1.8 The unit allows the operator to accurately measure the range to a stationary or moving object.
The unit displays the range in tenths of feet (tenths of meters), with +6” (+0.15 m) accuracy. The
unit will measure range from 10.0 feet to 8,000 feet (3.1 to 2438 meters)
1.8.1 The unit operates from four (4) AA batteries either alkaline (LR6*) or NiMH (HR6*) rechargeable.
The unit will also operate, as a USB “device” from a standard USB cable connected to a
computer or USB power supply.
(*LR6 and HR6 are IEC names for Alkaline and NiMH AA size electrochemical cells)
1.9 The unit incorporates an automatic self-test feature which verifies the operation of the unit upon
power-up and whenever the manual “Test” (check) switch is depressed for three (3) seconds.
1.10 All switches used on the unit are waterproof push button membrane style with tactile feedback.
1.11 The rear panel display is a 256 x 64 graphical OLED (Organic Light Emitting Diode), which does
not require any backlighting.
1.12 The factory aligned Head-Up-Display (HUD) is a green OLED display.
1.13 The laser, glass optics and all electronics are enclosed in a metal housing which has a
permanent forward swept handle. The dimensions of the housing, including handle, are 9.00”
high by 4.21” wide by 6.0” long, with a weight of 2.5 pounds including batteries.
1.14 The unit has a USB connector on the side, which when connected to a PC and appropriate
optional software, allows speed, range and unit functions to be displayed and recorded. The unit
is a USB “device”.

3. 1.15 The unit has a special internal crystal calibration mode, where the operating quartz crystal
frequency is available at an output connector. Normal unit operation is disabled while in this
mode.
2.0 DESCRIPTION OF FEATURES
2.1 The unit contains the following push button controls located on the rear panel:
a. Menu select the menu
b. Speed-Range/Up arrow select range or speed / “up” selector
c. Volume/Down arrow controls audio volume / “down” selector
d. Check activate test mode / accept new entry / Display Lock
e. Power/ Rear Panel Brightness turn unit on/off / control rear panel brightness
f. Weather/ HUD Brightness activate weather mode / control HUD brightness
2.2 The unit activates the laser by pulling the trigger, releasing the trigger will turn the laser off, which
also locks a valid displayed speed and range.
2.3 A valid speed will be shown in the HUD and rear panel displays. A dashed line “----“ indicate the
laser is firing, but insufficient data has been received to calculate and display any speed reading.
2.4 The unit provides an audible output when laser pulses are being returned from the intended
target. This provides the operator a tone to verify that the lidar is receiving reflected laser pulses
from the target. This tone will be a constant pitch, but will be staccato as pulses are first
received, increasing to a solid tone when proper data has been received and a speed displayed.
2.5 The unit has continuous tracking of vehicle speeds. When the operator holds the trigger
depressed, the unit updates the HUD and rear panel speed displays three (3) times per second.
2.6 The unit has a menu feature to select “continuous” speed tracking, or “single” speed mode. In
single speed mode, the unit turns off the laser and stops speed calculations after the first valid
speed is shown in the HUD and rear panel display. The trigger must be released and pressed
again to get a new speed reading.
2.7 The HUD has a selectable reticle of three (3) shapes. The HUD will show speed, direction and
distance of the target. There are five (5) steps of HUD brightness to accommodate various
ambient light requirements. The “range” reading in the HUD can be turned on/off via the menu
features.
2.8 The unit indicates the direction of travel of the target, whether approaching or receding. The HUD
will show a “+” sign if the vehicle is approaching and a “-“ if the vehicle is receding. The rear
display will show a “down” arrow if the vehicle is approaching and an “up” arrow if the vehicle is
receding.
2.9 The unit allows the user to select speed readings in either English (mph) or metric (km/h)
measurement systems.
2.10 The unit has an adjustable range control allowing the operator to select the distance at which
targets will be detected, both at maximum range and minimum range. The unit allows the
operator to preset the distance, or measure the distance to a known sign or target and increment
or decrement this measured distance as required. No target speeds will be displayed when the
intended target is outside the specified minimum and maximum limits.
2.11 The unit allows the operator to control by push button the audio volume in five (5) steps, with an
audio off position.

4. 2.12 When the “Test” (check) button is held down for three (3) seconds, the unit performs the following
self-test sequence:
a. EEprom test.
b. Timer test.
c. Calculate Checksum
d. End Self-Test.
2.13 The unit has a three (3) stage battery level gauge. The battery symbol on the rear display show
full, 2/3 full, 1/3 full.
2.14 The unit is equipped with a low voltage measuring circuit. If the power supply (AA batteries or
USB power) falls below a minimum voltage, a “Replace Batteries” message will appear the rear
display. This message alerts the operator that the battery, or the USB power supply is low. The
unit will not function once the “Replace Batteries” message appears. The unit must be turned off,
then on to reset this error condition.
2.15 The unit is equipped with a means to visually indicate the unit is sending out laser pulses. Four
(4) dash lines will be present in the HUD when transmitting laser pulses, but no speed or range
data has been displayed. The rear display shows a “laser” symbol whenever the laser is firing.
2.16 The unit accommodates normal use in adverse weather elements such as dust, rain and snow. It
is capable of being used in these environments without the use of covers or additional protection.
2.17 The unit has an inclement weather mode which allows the operator to select either normal or poor
weather. In this mode, targeting range is increased to a minimum of approximately 200 feet (61
meters). Since use of the lidar device in snow, rain, blowing dust or through the patrol vehicle’s
windshield may reduce targeting range, this mode will allow increased performance under these
conditions.
2.18 The unit has a stopwatch mode which allows the operator to either enter a known distance,
measure a distance from the lidar to a second point, or measure two points. Using this known
distance, the operator can use the trigger to start and stop the timing clock. The rear panel
display will show the known distance, elapsed time and calculated average speed. The unit has
an audio confirmation tone which sounds on activation of the trigger to confirm to the operator
when the timer is started and stopped.
2.19 The unit has a menu feature which allows the operator to select approaching only, receding only
or both directions of target vehicles.
2.20 The unit has a menu selectable feature for a differential distance test to be activated. This allows
the operator to obtain range readings on two targets and perform an internal timing test on the
difference between the two ranges. The difference distance is displayed in the range window and
twice the difference distance is displayed in the speed window.
2.21 The unit has a “display lock” feature. Once a valid speed is acquired, and the trigger is released,
momentarily pressing the “check” key will lock the display. A “lock” symbol will appear and the
trigger button is disabled. The speed/range is locked. The “check” button must be pressed to
unlock the unit.
2.22 The unit keeps track of the last 1,000 events. An event is a valid speed reading when the trigger
is released. The event data consist of Speed, Range, Date, Time, Tracking Seconds. The events
data can be recalled onto the rear display or downloaded using the USB connection.
2.23 The unit has a real time clock (RTC). The RTC is adjustable by using the rear panel button, or
remotely using the USB connection. The RTC has a separate battery to power it when the AA
batteries and USB power are not present, so it will keep time without the AA batteries.

5. 2.24 An optional USB Power Supply is available from the manufacturer. It plugs in to a normal 12 volt
cigarette lighter socket in a car. A normal USB cable will connect the USB power supply to the
lidar unit.
