Humminbird NS 10 Operation Manual page 61

Position 4, the boat has deviated substantially from your planned route due to oncoming
traffic or other unforeseen hazards. This scenario illustrates the information the NS 10 will provide
in this situation. As you begin to deviate to the left of the route, a LEFT OF COURSE indicator
appears, and the desired course line begins to drift to the right of the steering indicator. If the turn
is continued, a point is reached where it would be more expeditious to continue the left turn to
return to the route, rather than turn back to the right. At this point, an audible alarm will sound and
a warning message will appear in the graphic display area stating HEADING AWAY FROM
WAYPOINT. The current route line is no longer visible on the "forward-looking" view.
