OPERATION

single hand-held unit: -- optional shoulder stock
-- optional tripod mount
Power Source: -- car battery, or
-- internal battery (in handle).
Aim Device: -- Heads-Up Display (HUD)
Targets: -- on-coming and going
-- measures speed and range
Modes: -- Single Shot (short track)
-- Track (continous track)
---- Inclement Weather*
-- Distance/Time (no transmissions)
Testing: -- Self Test on POWER ON
-- Self Test using TEST switch
-- Test HUD and BEAM alignment
Data units: -- English (mph, ft), or
-- Metric (km/hr, m)
Beam: 3 mRad ± 0.5 mrad
0.14° to 0.20°
Sample Time: < 0.4 seconds

* -- Inclement Weather mode suppresses echoes closer than about 250 feet (intended to reduce interference from rain, fog, snow).


CONTROLS

PWR Power ON/OFF
-- On power up runs self test (see below)
TEST run Self Test
-- test circuit elements
-- timing accuracy verified
-- display elements illuminated
Errors indicated by beep code

Alignment Test (press TEST and TRIGGER)
-- Test HUD-Beam alignment (with audio tone)

TRIGGER Lidar mode
-- xmit while pressed (short track mode).
-- press onec to start, again to stop (track mode).

TIME/DIST mode
-- separate depressions when target enters
and exits speed zone.

SPEED / RANGE selects
-- Single Shot mode
-- Track mode
-- Inclement Weather mode
toggles between
-- Speed only
-- Range only
-- Range and Speed
-- exits MIN, MAX, and TIME/DIST modes
AUDIO volume adjust (4 steps)
TIME/DIST Selects Time / Distance mode
MAX update maximum range (TIME/DIST mode)
MIN update minimum range (TIME/DIST mode)
HUD Light 6 brightness levels
PANEL Light LCD and Panel backlights ON or OFF


DISPLAYS / INDICATORS

HUD Heads Up Display
-- Aim Point
-- ± Speed
-- Range
Panel Display LCD

-- ± SPEED
-- RANGE

-- PWR (power on)
-- TEST (self test running)
-- PASS (self test passed)
-- Err (self test detected an error)

-- CLEAR (activates prior to new reading)
-- LOCK (speed in display locked)
-- EMI icon (Electromagnetic Interference)

Speaker Tone proportional to target speed
-- faster target has higher pitch tone
-- intermittent tone, beam off target
-- no tone, no target in beam
-- also used to test HUD-BEAM alignment

Speed Range ± (1 to 299) mph
± (1.6 to 481) km/hr
Speed Accuracy +1 mph, -2 mph
+1.6 km/hr, -3.2 km/hr
Nominal Range Minimum < 5 feet (1.5 meters)
Maximum > 4000 feet (1200 meters)
Range Accuracy < = 1 foot (1/3 meter)
