Size - 1.65" Height, 1.05" Depth, and 5.50" Width Counting unit Weight - 1.6 lbs. Size - 1.65" Height, 3.90" Depth, and 5.50" Width Antenna Weight - 1.4 lbs. Size - 2.50" Dia. X 4.75" Length Remote Weight - 0.4 lb. Size - 1.00" Height, 6.20" Length, and 2.25" Width Accuracy: +1, -2 mph stationary, ±2 mph moving +2 / –3 km/h stationary, ±3 km/h moving Automatic Self-Test: Performed every 10 minutes Stationary Speed Range:12 mph to 200 mph Standard or 2 mph to 200 mph (set-up menu selectable) Stationary Fastest Speed - Same speed range as stationary speed Moving Speed Range: Patrol speed – Once acquired, will track to 150 mph. Acquistion speed is selectable with P.S. 5/20 key. 5 in patrol window for patrol speed acquistion speeds of 5 to 90 mph; 10 in patrol window for patrol speed acquistion speeds of 10 to 90 mph; 20 in patrol window for patrol speed acquistion speeds of 20 to 90 mph Opposite lane target speed – 200 mph Max closing For 5 mph patrol speed: 20 mph to 195 mph; For 70 mph patrol speed: 35 mph to 130 mph. Opposite lane Fastest Speed – Same speed range as opposite lane speed Same lane target speed – Related to patrol speed: ±70% of patrol speed within 5 mph of patrol speed. For 50 mph patrol speed: 15 → 45 mph and 55 → 85 mph. Same lane patrol speed must be greater than 15 mph
