3. The audio alarm sounds. Press the CANCEL key to silence the audio alarm.
4. Communicate with the coast station via radiotelephone (CH16) as below.
a) Say “MAYDAY” three times.

Note: If you do not receive the distress alert acknowledge call, the equipment automatically re-
transmits the distress alert after 3 min 30 seconds to 4 min 30 seconds. Then the equipment
awaits the distress alert acknowledge call. This is repeated until the distress alert is acknowl-
edged.
