Chapter 5: Digital Selective Calling (DSC) 75
5.5 Group Calls
The Group Call feature sends transmissions that are only received by radios
sharing a common Group MMSI number, such as a flotilla or racing fleet. The
Ray49E sends Group Routine calls.
Group MMSI Setup
You can program up to three Group MMSI ID numbers. Group MMSI ID numbers
always begin with a zero (0). You only enter the last 8 digits of the Group ID
number; the initial “0” is automatically entered for you.
