5.2  TARGET TRACKING OPERATION 
 
 
This section explains how to use the target tracking function. 
The target tracking function automatically tracks a target, and displays the target's course and speed as vectors.   
The target tracking function calculates CPA and TCPA, and issues an alarm as needed. 
The tracking data is erased from memory when the power is turned off or during transmission standby. 
 
 
5.2.1    Acquiring Target [ACQ] 
 
Target acquisition can be performed on two modes, Automatic and Manual, and both modes can be used at the 
same time.
