Restarting navigation
When you steer to avoid an obstacle or the
vessel drifts, you may go off your intended
course (Line 1 in Figure 7-7). Use the steer-
ing or highway display to return to course.
Also, if you don’t need to return to the origi-
nal course, you can go directly to the waypoint
(Line 2 in Figure 7-7) using the restart func-
tion as on the next page.

Switching waypoints
When you arrive to a waypoint on a route,
you can switch to the next waypoint three
ways: AUTO1, AUTO2 and MANUAL.
AUTO1: Automatically switches the TO
waypoint when your boat is within the arrival
alarm area. For how to set the arrival alarm
area, see “8.3 Arrival Alarm” on page 8-1.
AUTO2: Automatically switches the TO
waypoint when the boat enters the arrival
alarm range or the boat passes an imaginary
perpendicular line passing through the cen-
ter of the destination waypoint.
MANUAL: When the boat enters the arrival
alarm area, the TO waypoint may be switched
by using the soft key RESTART (on the LOG
display). If the arrival alarm is not set, the
waypoint will not be switched. To be alerted
when you arrive at a waypoint turn on the
audio alarm. For further details, see “8.2 Au-
dio Alarm On/Off” on page 8-1.
