When operating the AP50 in NAV mode to automatically steer 
through a route of waypoints, the AP50 will steer to the first 
waypoint in the route after you accept the first waypoint as the 
location to steer towards. 

 

If you use a GPS/Chart plotter, the AP50 will, when you arrive 
at the waypoint, output an audible alarm and display an alert 
screen with the proposed new course information. If the required 
course change is more than 10

°, you will need to verify that the 

upcoming course change is acceptable. 

 

Verification is performed by pressing the NAV button or turning 
the course knob after the alert screen is displayed. If an external 
alarm unit (optional) is connected to the AP50 system, an alarm 
is given after 5 seconds. If no verification is received, the AP50 
will continue on the current set course in NAV mode.
