Group MMSI Number

Nautical organizations like yacht clubs and regatta event organizers can establish Group MMSI numbers. Messages can then be automatically transmitted to all members of a group without making individual calls.

The Group MMSI is established by modifying the MMSI assigned to one (1) group member. To modify the MMSI number, drop the last digit of the number and insert a zero

(0)at the beginning.

Example:

Member MMSI number 366123456 becomes Group MMSI number 036612345.

Group MMSI numbers may be entered and changed any time without resetting the radio. Each member of a group must enter the group MMSI number in their radio to receive group messages.

NOTE

ALL digits must be entered for the display to show complete.
