3.5.26.4 Transmitting a Group Call

You can send and receive DSC calls from groups of stations that share the
same MMSI number. There are three types: ROUTINE for normal calls,
SAFETY for advisory alerts, and URGENCY for assistance when life is not
in immediate danger.
The RAY230/230E can receive all three types of Group calls but can only
transmit ROUTINE Group calls. As with any DSC operation, the call is
made on channel 70.
To make a Group Call:
1. Set up the Group MMSI number as outlined in Section 3.5.30.3.4.
2. Press the INDV key. Ind appears on the 7-segment display, the DSC
indicator is illuminated, and SHIP appears on the dot matrix display.
3. Press the SQ UP/DOWN key to alternate between SHIP, SHORE, and
GROUP. Stop on GROUP. The GROUP message only appears if you
have set up the Group MMSI number as outlined in Section 3.5.30.3.4.
4. When GROUP appears, press the ENT key. GrP appears on the 7-
segment display and the registered Group MMSI number appears on
the dot matrix display.
Note: Since only one group MMSI number can be registered at a time,
only one MMSI number can be displayed when GROUP is selected. To
change the group MMSI number, see Section 3.5.30.3.4.
5. Press ENT to accept the MMSI number.
6. Use the SQ UP/DOWN key to select the Working Channel for
communication.
7. When the desired channel number appears, press ENT. The dot matrix
display scrolls between the Working Channel and the Group MMSI
number.
