Switching waypoints

When you arrive to a waypoint on a route, you can switch to the next waypoint by one of the three methods below.

PERPENDICULAR: Automatically switches the destination waypoint when the boat comes passes an imaginary perpendicular line passing through the center of the destination waypoint.

ARRVL ALM CRCL: Destination waypoint is automatically switched when the boat comes within the arrival alarm range. For how to set the arrival alarm, see the paragraph 3.11.2 Arrival alarm.

MANUAL: The destination waypoint may be manually switched by using the RESTART soft key (see page 3-49). This function is operative when “1 POINT” is selected as the GOTO method (see page 3-44).
