4.4 How to Filter AIS Targets
If the screen becomes cluttered with AIS targets, you can filter out unnecessary AIS
targets, from the [DISP FILTER] menu.
1. Right-click the AIS mode indication then click [AIS Menu] to show that menu.
2. Open the [5 DISP FILTER] menu.
3. At [1 SLEEPING CLASS A] - [5 VIRTUAL ATON], disable or enable tracking of
respective item as appropriate.
4. Select [6 MAX RANGE] and set the maximum range to display an AIS target. An
AIS target not within the range set here is not displayed.
5. Set the minimum ship speed for AIS targets, with [7 MIN SHIP SPEED]. Any AIS
target whose speed is slower than that set here will not be displayed.
6. Close the menu.
Note: This function is not available for an activated target.
