No patrol speed (unit

Weather conditions (heavy rain,
snow or fog) may affect the Eagle
II’s ability to pick up groundspeed.
Verify the patrol speed is above
the minimum patrol speed setting
and below 100 MPH (160 km/h).
To check the setting, press
PAT/SEL. To change the setting,
press MODE.
Place unit in stationary mode and
unsquelch audio. Drive patrol
vehicle and verify the TARGET
window displays proper
groundspeed and the Doppler
audio is free of interference. If no
speed-readings are obtained, or no
Doppler tone is heard, change
antennas.
If speedometer input is used:
Verify unit is synchronized to
patrol vehicle (see Sec. 6.7).
Verify patrol speed is above 10
MPH (16 km/h).
Verify antenna is aimed
properly and is not obstructed.
Remove unit from service if above
tests fail.
