14. AIS TARGET FUNCTIONS
14-8
14.6 Activated Targets
When you change a sleeping target to an activated target, the target’s course and
speed are indicated with a vector. The vector can be monitored to find vessel move-
ment.
To activate a sleeping target, put the cursor on the target then press the ACQ/ACT
key.
When the screen gets full of activated targets, it is difficult to discriminate the radar
display and tracked targets. When this occurs, sleep some activated targets to clear
up the screen.
