danger
Use this distress procedure:

• If no answer, repeat; then try another
channel
Caution
Every ship at sea is to obliged to give
absolute priority to radio
communications relating to ships in
distress - it is vital that false distress
calls or messages not be broadcast.

communications with
another station

communications with
another station
And - you do not know what
working channel the
