6.5  Setting and Operating Target Tracking 
The Target Tracking function automatically tracks the acquired targets and records and displays the 
course and speed of the targets as vector. Alerts can also be output based on the set collision decision 
criteria (CPA and TCPA). 
 
Note 
At power off and during preparation for transmission, tracking data records are deleted. 
 
6.5.1 Acquiring target 
The methods for acquiring targets include Auto Acquisition (automatic acquisition) mode and ACQ 
MANUAL (manual acquisition) mode. 
Both modes can also be used concurrently. 
 
6.5.1.1  Automatic acquisition (automatic acquisition) mode 
By setting up and enabling the automatic acquisition/activation zone (AZ), targets intruding into the AZ 
can automatically be acquired/tracked and also issue a new target warning. 
 
Note 
If manual acquisition is made in a state in which the number of targets being tracked has reached 
the maximum number of targets, the target with the lowest danger level among the targets that 
have been captured thus far automatically is erased successively. 
When all the targets that are tracked are for manual acquisition and the number has reached the 
maximum number of targets, no further acquisition is allowed. 
 
 
Take the following steps to enable automatic acquisition/activation zone (AZ). 
1  Click on the [Menu] button on the left toolbar. 
The menu is displayed. 
2  Click [Alert] - [New Target Alarm] on the menu. 
The [New Target Alarm] dialog is displayed.
