2.9 Emergencies and warnings
You can use your C-Series display to mark the position of a man overboard or to sound
an alarm when a particular situation occurs e.g when a depth limit is reached, a
specified period of time has elapsed etc.
Man Overboard (MOB)
Marking a MOB
If you lose a person or object overboard, and need to return to the location, you should
use the Man Overboard (MOB) function immediately. The MOB function can be
used whilst any application is in use and is activated by either pressing and holding the
WPTS/MOB key for three seconds, or by a MOB message being received from other
equipment on the SeaTalk system.
When a MOB is activated the following is initiated automatically:
Alarm - the MOB alarm is triggered (Morse --- every 30 seconds).
Waypoint - a MOB waypoint is placed at your current position.
Positional information - the bearing, range and vessel position are displayed in
the data bar. These are calculated according to the MOB data type set in the System
SetUp (see
page 183
). Assuming that your boat and the MOB are subject to the
same tide and wind effects, dead reckoning normally gives a more accurate course.
Radar range change - if radar is transmitting, the system changes the radar
range to
1
/8 nm.
Active navigation is suspended - Navigation to any active waypoint is sus-
pended and any existing navigation function is cancelled. No further GOTO or route
functions are selectable whilst the MOB function is active.
Autorange motion mode - If radar/chart synchronization is set to OFF (see
page 76
), the chart application changes the motion mode to Autorange.This dis-
plays the largest possible scale of chart that will include both the target waypoint
(MOB symbol) and your on-screen vessel.
Other equipment - other Raymarine equipment acknowledges the MOB.
Current position to MOB position - as your vessel moves away from the MOB
position, a dotted line is displayed from your current position to the MOB position.
Note: To obtain a MOB position, you need either position data from a GPS (or equiva-
lent device) or heading and speed data.
