■ Receiving DSC calls
IMPORTANT!
Distress call reception should stop after one
sequence because the coast station should
send back an ‘acknowledgment’ to the ship.
If the distress call continues, even
after the coast station sends back an
‘acknowledgment,’ the ship in distress may
not receive the acknowledgment.
In such cases, you should send back an
‘acknowledgment’ instead of the coast
station and contact the coast station.

To send the acknowledgment,
