The 941X's plotter provides a picture of your position, and of what is
around you. Nearby waypoints, avoidance areas, and a lat/lon grid may
be displayed along with an image of your boat.
When you are using the plotter, the five menu keys below the display
screen allow you to perform the following functions:
1) restart the desired track line to run directly from your position to the
waypoint, "zeroing" the cross-track error display
2) change the options available for the plotter
3) center the image of the boat on the screen
4) zoom in to show more detail
5) zoom out to show more area
See page 22 for more information on using the plotter.
