How to use APR-1

FOTRSU 1.7
Just had it fitted on my boat. How is it used? I assume it's a passive device, in which case how will I be alerted that it's picking up enemy radar?

With map contacts enabled, you should see a line as would sonar, except it will be at a much greater distance than sonar so easy to distinguish. In the dialogue box at top of screen, crew may report "Detecting Radar Signals", sometimes, they do, sometimes they do not.
