MAKING A DISTRESS CALL
The DISTRESS key is used to make a Distress call. A Distress call will send out the position and time information from the input NMEA data along with your MMSI number. This digital information lets other ships and shore stations equipped with appropriate DSC equipment know where you are and that you are in a distress situation.
WARNING: Unless you need immediate help, NEVER use the DISTRESS key. Violators can face felony charges, prosecution, significant fines, and/or incarceration. NOTE: You can only initiate a Distress call when you have a MMSI assigned to your radio and you have DSC enabled. See the Maritime Mobile Service Identity (MMSI) section for more information. NOTE: For more information about using your radio in a distress situation and how to comply with Coast Guard regulations, refer to http://www. navcen. uscg. gov/marcomms/. Refer to the FCC website: http://wireless. fcc. gov/marine/ for general and technical VHF Marine Radio license, specifications, and regulation information.
