3. WAYPOINTS (MARKS)
3.1 Entering Waypoints
In navigation terminology a waypoint is a
particular location on a voyage whether it
be a starting, intermediate or destination
waypoint. Your unit can store 950
waypoints. Waypoints can be entered on
the plotter display four ways: at cursor po-
sition, at own ship’s position, through the
menu (manual input of L/L or TD), and by
MOB position.
Entering a waypoint by the cursor
1. On the plotter display, use the cursor
pad to place the cursor on the location
you want to make a waypoint.
2. Press the [ENT] key. The following win-
dow appears.
