TRESS key. The audio alarm sounds for two seconds.
After the distress alert has been sent, the following screens appear in order.
3. The audio alarm sounds. Press the CANCEL key to silence the audio alarm.
4. Communicate with the coast station via radiotelephone as below.
a) Say “MAYDAY” three times.

transmits the distress alert after 3 min 30 seconds to 4 min 30 seconds. Then awaits the distress
alert acknowledge call. This is repeated until the distress alert is acknowledged.
