Uniden Waterproof DSC Marine Radio UM380 - Manual (Page 26)

22 English
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:
x Throughout the race, you use
group calling to update the
racers on the time, race status,
and any course corrections.
x
A power boat full of
spectators comes a little too
close to the race path. You use
individual calling to contact
the power boat and advise
them to stay clear of the race.
x You see a rowboat entering
the area, but since it doesn’t
have a radio, you can’t
communicate with the
rowboat. You use all ships
calling to alert all the other
boats in the area of the
possible danger.
