Mob Mode; Dsc Vhf Radio Integration - Raymarine LIGHTHOUSE 3 Advanced Operation Instructions

The MOB feature requires your vessel to have a valid position fix from a GNSS (GPS) receiver. Dead
reckoning mode also requires Heading and Speed data.
When you activate the MOB alarm:
• an audible alarm is sounded which is repeated every 30 seconds until the alarm is cancelled.
• a MOB Databar providing Bearing and range from MOB, and elapsed time since MOB was initiated,
is displayed along the top of the screen. The Databar persists across apps and the Homescreen,
and remains until the MOB alarm is cancelled.
• a MOB warning is displayed in the bottom of the screen, which requires acknowledgement.
• the Chart app is placed in a special MOB mode to help you navigate back to the point your vessel
was at when the MOB was initiated.

MOB mode

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. You can change the MOB mode at anytime from the
Alarms menu: Homescreen > Alarms > Settings > MOB data type:.

call is received by your DSC VHF radio a notification is also displayed on the MFD.
