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 96.
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.
Select DSC MENU GROUP.
The display shows the names of your pre-programmed groups.
Select the group that you want to call.
On the "CHOOSE CH" screen, select INTER-SHIP. (Or, select MANUAL
to use a duplex channel—see point 2 of "General usage" on page
46.)
The display shows "SET INTER"
Use or to reach the working channel you want to specify and
press [OK].
When the SEND prompt appears:
•
Press [OK] to send the call request on CH70, or
•
Press [X] to exit without sending.
For information on receiving a group call, see "Receiving a DSC
Note:
group call" on page 60.
