5. NAVIGATION
5-3
A red line runs between the points on the route. The line shows the shortest path
to the destination and the direction to go.
The arrival area, the radius of which is set with the arrival alarm, is shown with a red
dashed circle. When your boat comes within the circle or your boat moves through
an imaginary perpendicular line that crosses through the center of the destination
point, the audio alarm sounds and the arrival alarm icon appears at the top of the
screen to alert you. See the description on page 5-1.
After you arrive to a point, the arrival area marker and the dashed line are switched
to the next waypoint.
