D Receiving a Distress Call
IMPORTANT!
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
after the coast station sends back an
'acknowledgement,' the ship in distress
may not receive the acknowledgement.
In such cases, you should send back
an 'acknowledgement' instead of the
coast station and contact the coast
station. (p. 34)
