If in an emergency situation, press the large independent Distress button to send an automated digital Distress signal. The digital distress signal with GPS coordinates calls for help from other ships or coast stations.
The dedicated DSC watch-keeping receiver continuously scans the six distress channels in rotation. A total of 100 MMSI numbers (75 Individual and 25 Group) for DSC calls can be stored with a 10-character ID name. When you receive a DSC call, while you are in process with another DSC call, the IC-M803 can hold both DSC procedures to switch between the DSC calls with the Multiple Task Mode function.
