10.8 Vdc. When supply voltage decreases below
this, a message of "Lo bAt" is displayed on the
front panel to warn the officer of a low voltage
condition.
10.8 Vdc-16.5 Vdc
(13.6 Vdc Nominal)
Standby, no displays (0.3A typical)
Front antenna "on", no target (0.4A typical)
Front antenna "on", with target (0.5A typical)
Front antenna "on", during LED test (0.7A typ.)
Stationary mode operating speed range is from 15
mph up to 200 mph for K or Ka-band units. X
band operating speed is 20 mph to 209 mph.
In opposite direction mode, Patrol Speed range is
20 mph to 100 mph in highway mode and 12 mph
to 80 mph in city mode. Target Speed range is 20
mph up to a closing speed of 200 mph.
In same direction mode, Patrol Speed range is 20
mph to 120 mph in highway mode and 12 mph to
80 mph in city mode. Target Speed range is patrol
speed ±70%. There must be a minimum
difference of 3 mph between target and patrol
speeds.
-30°C (-22°F) to 60°C (+140°F)
Operates normally up to at least 90% relative
humidity at 99°F (37°C).
The radar automatically and invisibly checks itself
for proper operation. If an error is detected, the
fault is indicated in the middle window.
