Sending a group call
A group MMSI is a shared MMSI. When a DSC call is transmitted by
one of the vessels in the group, all the radios that have the same
MMSI entered will receive the message, and can reply on the chosen
channel if necessary.
To enter a group MMSI, see “Creating a group MMSI” on page 85.
¼ Notes:
• Unlike the DSC or ATIS MMSI, a group MMSI can be changed at
any time.
• Group calls are always sent with ROUTINE priority.
• No DSC acknowledgement is required for a group call.
1. Select DSC MENU → GROUP.
2. The display shows the names of your pre-programmed groups.
3. Select the group that you want to call.
4. On the “CHOOSE CH” screen, select INTER-SHIP. (Or, select MANUAL
to use a duplex channel—see point 2 of “General usage” on page
51.)
The display shows “SET INTER”
5. Use ▲ or ▼ to reach the working channel you want to specify and
