Chapter 5: Digital Selective Calling (DSC)
85
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
Ray218E/Ray55E sends Group Routine calls.
Group MMSI Setup
You can program up to five Group MMSI ID numbers and associated Group
names, which can be up to 11 characters long. 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.
Adding a New Group
1. Select GROUP from the DSC Menu.
2. Select MY GROUP ID. If an existing Group name and MMSI ID number are
already stored, those values appear. If blank, <EMPTY 1>, <EMPTY 2>, etc.
are shown to indicate that the Group IDs have not yet been programmed.
Select the first available empty group location. The first field for you to enter
data is the GROUP MMSI number.
3. Fill in the GROUP MMSI field one number at a time. The leading “0” is auto-
matically entered for you. The first character space you can modify is high-
lighted with a flashing underline. A more-detailed description of manual
character entry can be found in “Adding a new Entry“ on page 79.
4. Rotate the
CH/OK
knob. The flashing underline is replaced with a numeric
character. Continue rotating the knob to scroll through the selections. Use the
< and > soft keys to edit selected characters, if necessary.
5. When the appropriate number appears, press the
CH/OK
knob to accept. The
next character to be filled in sequence is then underlined. Continue this pro-
cess until all GROUP MMSI characters have been entered.
When you press the
CH/OK
knob to accept the final MSSI ID digit, the cursor
moves on to the GROUP NAME. The first character space to be modified is
highlighted with a flashing underline.
6. Using the same procedure as above, rotate the
CH/OK
knob to select the
GROUP NAME characters. All alpha and numeric characters are available, as
well as 13 symbols:

7. Press the
CH/OK
knob to accept. Continue this process until all GROUP
NAME characters have been entered.
8. When complete, press the DONE soft key to accept. The new entry appears in
the list.
