4. WAYPOINTS, NAV LINE
23
Note:
Waypoints are automatically switched when own ship is either 1/2 of
the arrival alarm range or 0.5 nm from next waypoint, whichever
figure is larger. For example, the arrival alarm range is 2 miles. Since
1/2 of the arrival alarm range is 1 mile and it is larger than 0.5 miles,
the waypoint will be switched when your ship is 1 mile from a next
waypoint.

use the WPL for destination waypoint, set USED WPL# to WPT in the
NAV INFORMATION 3 menu. This should only be used when connected

longitude position of waypoint, course, etc.
