12.8 Test Call
This function sends a test signal to a coast station, over one of six distress and safety
frequencies. For that reason, it should not be executed unnecessarily. You can prepare a
test call beforehand (see Chapter 6) or at the moment you intend to send a test call. To
send a prepared test call, see page 6-9 for the procedure.
