[II]  Vector Length: VECTOR TIME 
 
The vector length of a target is proportional to its speed, and the vector time can be switched in a range of 1 to 
60 minutes by used for ten-key. 
The diagram below illustrates a vector length of a target for six minutes, and the tip of the vector represents the 
target’s position expected to reach six minutes later. 
 
 
 
 
 
 
 
 
Refer to Section 5.1.4 Setting Vectors for how to change the vector time.
