Section 7--System Operation
7.2
7.1.
Setup
1. Select a location that provides a good view of the traffic
to be monitored.
2. Check the immediate area for potential interference
sources, such as large reflecting signs in the direct path
of the radar's microwave beam, power substations and
other sources of electrical interference.
3. Position the patrol vehicle in a safe location, with easy
access to the roadway.
NOTE: Cosine error (angle between the target's direction
of travel vs. the path to the radar), in the stationary
mode, will ALWAYS be in the driver's favor.
Refer to the National Highway Traffic Safety
Administration's "Basic Training Program in
RADAR Speed Measurement" for speed reduction
information due to cosine angle effect.
4. Adjust the Doppler audio for the desired listening level.
Depress the AUDIO switch. The TARGET window
will display "Aud" and the PATROL window will
display the current audio level.
With "Aud" still being displayed, depress either the
AUDIO (down) or RANGE (up) switches to decrease or
increase the audio level. The displays will return to their
normal mode two seconds from the last switch entry or
momentarily depress the HOLD switch to return to
normal operation immediately.
5. To unsquelch the audio, depress the AUDIO switch. The
TARGET window will display "Aud". Depress the
MODE switch. The LOCK window will display "Un".
