5.4  DECISION OF TARGETS AS IDENTICAL 
(ASSOCIATION)
 
 
 
CAUTION 
If a great value is set as a condition for deciding targets as 
identical, a tracking target near an AIS target is regarded as 
identical to the AIS target and it may not be displayed any 
more. 
For example, when a pilot boat (which is a small target not 
being tracked) equipped with an AIS function approaches a 
cargo ship as a tracking target not equipped with an AIS 
function, the tracking target symbol of the cargo ship may 
not be displayed any more.

Setting of Function to Decide Targets as Identical (Association) 
 
When an AIS target and a tracking target are decided to be identical, an association symbol is displayed for 
the targets regarded as identical.    In this case, the AIS target symbol is automatically activated. 
 
 
 
z  Turn off  Association  in order not to make a decision 
on if targets are identical, or in order to display 
symbols that have disappeared.
