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:
• the buzzer sounds
• the Alert 521 "TT New Target" appears in the [Alert] box
• the symbol of the target is red and flashes
• the AIS function is automatically turned on if it is off
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].
