3.  TARGET TRACKING (TT)

You can set an automatic acquisition zone to automatically track any targets entering 
the zone. The acquisition zone can be fan-shaped or polygonal. For the fan-shaped 
zone, the range is fixed at a 3-6 NM (width 0.5-1.0 NM). The polygon zone can be set 
within the range of 0.125 NM to 120 NM. (However, automatic acquisition occurs only 
between 0.1 to 24 NM (or 32 NM)). The maximum tracking range is set during the in-
stallation.

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. "AZx SET" (x=1 

or 2) appears in the box.

2. Click point A.
3. Click point B. The box now shows "AZx 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).

Use the trackball to select the appropriate AZ box. Sleep or deactivate the acquisition 
zone as appropriate:
Sleep acquisition zone: Push the left button momentarily to remove the acquisition 
zone from the screen. The indication in the AZ box changes from "WORK" to "SLEEP." 
To reactivate and display the acquisition zone, repeat this procedure to display 
"WORK." 
Deactivate acquisition zone: Click applicable AZ box and select [Off].

Press the ALARM ACK key, or click the [Alert] box.

•  the symbol of the target is red and flashes
•  the AIS function is automatically turned on if it is off
