8. Field Tests
You shall do the following tests to verify the operation and accuracy
of the Genesis II Select™.
8.1 Operator-Requested Self Test
Pressing the TEST button initiates a comprehensive system self test
checks the following:
DISPLAY TEST: Allows the operator to verify that the digit segments
and status LED lights are working correctly and that none of the
pixels in the number segments are burned out.
CIRCUITRY TEST: Checks the internal circuitry. If the unit passes all
internal checks, the messages ROM PASS, RAM PASS, and DSP PASS,
and TEST PASS will be displayed, or if the test fails then FAIL will be
displayed in the MODE window and the unit should be removed
from service.
SPEED SIMULATION TEST: Verifies the speed accuracy using
synthesized Doppler frequencies corresponding to a series of four
simulated speeds: 25, 50, 75, and 100 km/h. These speed are first
displayed in the patrol window and then in the target window. In
each case the speed being displayed is accompanied by a audio tone
that is proportional to the speed being displayed (speed increases,
pitch increases). Once the test is successfully completed, a TEST PASS
will be displayed, followed by a single tone and then followed by a
two tone audio tone.

8.2 Road Test
After the radar unit passes the self test, conduct a road test to
confirm the correlation between the patrol vehicle speedometer and
the patrol speed displayed on the radar.
