Using Man Overboard (Mob) Functions - Raymarine e7D Installation And Operation Handbook

11.1 Using Man Overboard (MOB)
functions
Man overboard
If you lose a person or object overboard, you can use the Man
Overboard (MOB) function to mark the position that the vessel was
at when the MOB function was activated.
The MOB function is available at all times, regardless of which
application is running. MOB can be set to Dead Reckoning or
Position mode. Dead Reckoning mode will take into consideration
the effects of wind and tides. This usually provides a more accurate
course. Position mode does not take these factors into account.
To obtain a MOB position, your multifunction display must have a
GPS position fix. If you're using dead reckoning, heading and speed
data must also be available.
When MOB is activated:
• An audible MOB alarm is sounded.
• An MOB alarm dialog box is displayed.
• The system sends MOB alarms to other Raymarine equipment.
• The active chart application is changed to a low-detail 2D view,
with an initial range of 15 m (50 ft). Motion mode is set to Auto
Range.
• The active radar application range is changed to 230 m (760 ft).
• All Goto and Follow functions are disabled in all applications.
Navigation to any active waypoint is stopped and any existing
navigation function is cancelled.
• If position or heading and speed information is available a MOB
waypoint is placed at the current vessel position in any application
that is capable of showing waypoints and vessel position.
• MOB data is displayed in the databar, replacing the existing data.
• MOB data is displayed on the homescreen, replacing the status
icons.
• As the vessel moves away from the MOB position a dotted line is
displayed, joining the MOB position with the vessel's position.
When the MOB alarm is cancelled:
• MOB data is removed from the relevant applications.
• The chart application motion mode is reset.
• The chart is centered on the vessel and pitch / rotation set to
default.
• GOTO and route functions are restored.
• The databar mode is reset.
• A MOB normal mode signal is sent to any instrument on SeaTalk.
