Group Call - Uniden MHS235 Owner's Manual

Call type What it does
Distress Alerts all stations that you need assistance and
sends them your current position.
Individual Calls a single station using the User MMSI.
Group Calls all the stations that have the same Group
MMSI as yours.
All Ships Calls all stations within range of your radio.
Suppose you are coordinating safety for a sailboat race. Before the race starts, you instruct
all the racers to enter your group MMSI number into their radios. During the race:
Throughout the race, you use group calling to update the racers on the time, race
x
status, and any course corrections.
A power boat full of spectators comes too close to the race path. You use individual
x
calling to contact the power boat and advise them to stay clear of the race.
You see a rowboat entering the area, but since it doesn't have a radio, you can't
x
communicate with the rowboat. You use all ships calling to alert all the other boats in
the area of the possible danger.
