5.9 How to Use Waypoints
A particular location is known as a “waypoint”, whether it be a starting point, a desti-
nation point or an intermediate point on a voyage. This radar system can store 200
waypoints. Waypoints 1 to 198 are user set waypoints, waypoint 199 is reserved for
external input, waypoint 200 is reserved for MOB (Man Over Board). Waypoints can
be entered with the cursor, or from the menu (manual input of latitude and longitude).
Waypoints 1 to 198 can be edited from the menu.
