3.4.2 How to set an automatic acquisition zone
You can set an automatic acquisition zone to automatically track any targets entering
the zone. The acquisition zone can be fan-shaped or polygonal. The maximum track-
ing range is set during the installation.
Fan-shaped zone of AZ1: The range is fixed at 3 - 6 NM (width 0.5 - 1.0 NM).
Fan-shaped zone of AZ2: The range is available between 0.7 - 24 (or 32) NM (width
0.5 - 1.0 NM)
Polygon zone of AZ2: The zone can be set within the range of 0.125 NM to 120 NM.
Note: When processing two acquisition zones, create the zones in numerical order
and turn them off in reverse numerical order.
When a target enters an acquisition zone, the following occurs:
1. Click one of the boxes AZ1 or AZ2 at the right side of the screen. The indication
in the AZ box changes from [OFF] to [SET].
2. Click point A.
3. Click point B. The indication in the AZ box changes from [SET] to [WORK].
Note 1: You are alerted when the capacity for automatic acquisition is 95% and 100%.
These alerts are 522 "TT Auto ACQ 95%" and 523 "TT Auto ACQ 100%".
Note 2: If the range scale is changed to less than half of the acquisition zone, the AZ
box shows [OUT]. If the left button is pushed in this state, the acquisition alarm zone
goes into [SLEEP] state (inactive).
