3.9 Man Overboard (MOB)
If a person or object is lost overboard, and you need to return to the
location, use the Man Overboard (MOB) function.
Note: To obtain MOB position, a valid GPS fix must be available.
➤
To initiate the MOB procedure from the Chart display, press and hold the
GOTO
key for two seconds. The system performs the following tasks
automatically:
•
Stops any GoTo or Follow operation.
•
Selects a
1
/
2
nm scale (even if cartography is not available).
•
Marks the current position as a temporary waypoint with an MOB
symbol which replaces any current active waypoint and route.
•
Displays the MOB data box, showing the bearing and range to the
MOB position, the elapsed time since the MOB was initiated and
COG data (Figure 3-64).
Figure 3-64: MOB Data Box
•
Sends an MOB message, including bearing and range, to other units
in the system, via NMEA.
Notes: (1) A suffix (c) to the POSition data indicates that the vessel’s
position has been User Calibrated, see Chapter 4,Chart Set
Up Parameters.
(2) The
RANGE
key operates normally to change chart scale.
➤
To cancel MOB, press and hold the
GOTO
key for 2 seconds.
The MOB symbol and data box are removed and the unit returns to
normal Chart mode.
