3.8 Man Overboard (MOB)

If your RayData is connected via SeaTalk to other instruments with the
facility to handle "man overboard" (MOB) calculations, you can send
and cancel MOB warnings. Note that no waypoint data will be sent by
the RayData.

Sending an MOB Warning

To send an MOB warning, press the DEPTH and SPEED keys
together, as indicated by the MOB label on the RayData front panel. An
audible alarm sounds (unless this has been disabled using the Setup
option, as described in Chapter 4).
If there is no MOB Master instrument on your SeaTalk system, the
RayData screen will display the message "MOB NOT AVAILABLE".
If an MOB Master on the SeaTalk system responds, the audible alarm
stops and an MOB page such as the following is displayed:
This shows the location and distance of the MOB point you need to
steer towards, together with a steering bargraph. It is a special version
of the Waypoint/Bearing/Distance page (see page 56).
The MOB page is also displayed if a SeaTalk MOB message is
received from other instruments.
Note: Certain models of Raymarine chart plotters will respond to an
MOB warning from the RayData, and track to the MOB location, but will
not return the data for the RayData to display. In this case, you can turn
off the audible alarm by pressing any key. The message "MOB NOT
AVAILABLE" will be displayed until you cancel the MOB.
