The default AIS activation range is 5.0 nm. Any AIS target that is within 5.0 nm of your
boat is automatically activated. If you require a shorter or longer activation range, you
can change the range from the menu. Open the [SYSTEM] menu and select [AIS SET-
UP]. Select [ACTIVATION RANGE] and enter the range desired. (Note that tracking
continues internally on a maximum of 200 targets within 50 nm.)
