What does the DSC control unit do if the GMDSS Radio Operator fails to insert updated information when initiating a DSC Distress alert?

Correct Answer: Option C — It will initiate the DSC Distress alert, and default information will automatically be transmitted.

If manual position and time inputs are missing and no GPS interface is active, the DSC controller will still transmit the distress alert. It automatically inserts default values, such as "90 degrees North, 180 degrees East" for position, to ensure transmission is not blocked.
