Individual (routine)
Routine calls are used for contacting other vessels, marinas, or shore stations.
Routine calls are made on channel 70 using the dedicated Maritime Mobile Service Identity (MMSI)
number of the station to be contacted, selecting a VHF working channel and sending the call. Both
radios automatically switch to the chosen channel for conversation.
Routine calls can also be made to groups — When groups of ships need the same information (yacht
races, club rallies etc.) a special group-call identity can be used to enable restricted broadcast calls.
Note:
To transmit precise position data, the radio must be connected to a GNSS (GPS) receiver.
Otherwise, regular manual position updating is required.

When making a Distress call you can specify the nature of the distress, if GNSS (GPS) data is not
available you must also specify your coordinates.
Note:
Your radio must have an MMSI number saved before DSC functions can be used.
