Raymarine A series, Installation And Operation Instructions Manual

13.1 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 every 30
seconds until the MOB is cancelled.
• An MOB alarm dialog is displayed until it is
acknowledged.
• 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. As
the vessel moves away from the MOB position a
dotted line is displayed, joining the MOB position
with the vessel's position.
• 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.
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.
