MFD is sounding alarm every 30 seconds ... no message displayed

The Man Overboard (MOB) event is commanded by holding the WPT/MOB button pressed for approximately three seconds. When a MOB has been triggered,
- the MFD will produce an audible alarm and initially display a MOB alert dialog to notify the operator of a MOB event. Following the initial audible alarm, the MFD will sound an audible alarm at approximately thirty second intervals.
- the MOB's position, range, bearing, and time since the MOB event was triggered will be displayed within the Databar
- the MOB's position will be plotted on within the Chart application
- the Chart application will be configured to Auto Ranging in to better display the MOB's location in relation to the vessel
- any previously commanded navigation will be cancelled and a Goto event will be triggered to the location of the MOB. The MOB's position will be plotted on within the Chart application and the Databar.

One may easily verify whether a MOB event has been triggered by examining the contents of the Destination Waypoint Name within the Waypoint Info data item within a Databar, Databox, Data application panel data item, or by displaying the CDI panel within the Data application.

A MOB event may be cancelled by holding the WPTS/MOB button pressed for approximately 3 seconds. Once triggered, the only way to squelch the MOB event's audible alarm is to cancel the MOB event.
