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.

Automatically switches the TO waypoint when 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
comes within the arrival alarm range. For how to set the arrival alarm, see the
paragraph “2.11.2 Arrival alarm.”
MANUAL:
The destination waypoint may be manually switched by using the
RESTART soft key (see page 2-50). This function is operative when “1 POINT” is
selected as the GOTO method (see page 2-45).
