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.
NAV
SETUP
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.
