ing AIS targets, from the [DISP FILTER] menu.

2. Open the [5 DISP FILTER] menu.
3. At [1 SLEEPING CLASS A] - [2 SLEEPING CLASS B], disable or enable tracking
of respective item as appropriate.
4. Select [3 MAX RANGE] and set the maximum range to display a sleeping AIS tar-
get. A sleeping AIS target not within the range set here is not displayed.

Any sleeping AIS target whose speed is slower than that set here will not be dis-
played.
6. Close the menu.
Note: This function is not available for an activated target.
