Man Overboard (MOB) Navigation
As soon as you know that you have a man overboard (MOB) , you should activate MOB
navigation to maximize the chances for a successful rescue. MOB navigation allows you to
create an MOB waypoint to locate the point at which your man went overboard and the relation
of the boat to that point.
Activate MOB navigation: Press and hold the GOTO key for more than 1.5 seconds to activate
the Man Overboard (MOB) function.
When MOB is activated, a MOB waypoint is created at the boat's current position, regardless of
whether the chart cursor is active or not. The MOB waypoint has a large, distinctive icon. Once
MOB is activated, any current navigation will be cancelled and the current route will be
discarded without user notification. MOB navigation will begin immediately, and the MOB View
will show the following:
• The view will switch to the Chart View, and the elapsed time since MOB was activated
will be displayed.
• A line will be drawn from the boat's current position to the MOB waypoint, and the MOB
waypoint will be targeted.
• The latitude/longitude position of the MOB waypoint will be displayed in an additional
information box.
Cancel MOB Navigation:
From the Navigation X-Press™ Menu, select Cancel MOB, and press
the RIGHT Cursor key. Canceling MOB navigation removes the route and any waypoints created
using the GOTO key but does not remove any saved routes from memory.
It is not possible to re-activate MOB or modify the current route without first canceling MOB
navigation. The Off Course trigger is also disabled and the Off Course Alarm circle is not drawn.
Any press of the GOTO key, or selection of a GOTO menu option, will cause an error beep and
a short message will be displayed that will disappear after 2 seconds.
