D Sending a Distress acknowledgement
Distress call reception should stop after one
sequence because the coast station should send
back an 'acknowledgement' to the ship.
If the distress call continues even the coast station
send back an 'acknowledgement,' the ship in distress
may not be receiving the call.
In such cases, you should contact the coast station
via the phone and send back an 'acknowledgement'
on behalf of the coast station if the coast station
requires.
IMPORTANT: Distress acknowledgements should
be transmitted only on the 2187.5 kHz, according
to regulations (ITU-R 493-13). When you receive
a Distress call on other frequency bands, [ACK
(Distress)] is not displayed in the software key area.
