Switching waypoints
When you arrive to a waypoint on a route, you can switch to the next waypoint
three ways: perpendicular to waypoint, arrival alarm circle and manual.
PERPENDICULAR: Automatically switches the TO waypoint when the boat
enters the arrival alarm range or the boat passes an imaginary perpendicular line
passing through the center of the destination waypoint.
ARRVL ALM CRCL: Automatically switches the TO waypoint when the boat
enters the arrival alarm range. For how to set the arrival alarm, see paragraph
3.11.2 Arrival alarm.
MANUAL: MANUAL: When the boat nears a destination waypoint, the
destination waypoint may be manually switched by using the RESTART soft key
(see page 3-50). This function is operative when “1 POINT” is selected as the
GOTO method (see page 3-45).
