Garmin GPSMAP 376C - Manual (Page 136)

Non-Federal Users in the United States
Commercial users, or those who travel outside the United States or
Canada, must apply for a ship station license or an amendment to a
ship station license. To find out if you require a Ship Station license,
contact http://wireless.fcc.gov/marine/fctsht14.html . If your vessel
requires licensing by the FCC, you will obtain a MMSI during the
application/licensing process when you file FCC Forms 159 and
605.
Federal Users in the United States
Federal users can obtain MMSI assignments from their agency
radio spectrum management office. These procedures are currently
under review by the National Telecommunications and Information
Administration (NTIA).
Users Outside the United States
Users can obtain an MMSI assignment from their telecommunications
authority or ship registry, often by obtaining or amending their ship
station license.
Users In Canada
Industry Canada is responsible for assigning MMSI numbers to
commercial and recreational vessels. Information is available at the
following Web site: http://apollo.ic.gc.ca/english/mmsi.html .
How Can Garmin Help You with DSC?
To receive distress calls or position reports, you must have a
DSC-equipped chartplotter as well as a VHF radio with DSC
support. During normal, non-emergency position report
communication, Channel 70 (156.525 MHz) has been set aside as
the VHF/DSC digital call channel.
For a distress call, press the MayDay button on the VHF radio. The
call transmits on an emergency channel with the MMSI number
attached to the call, if the receiver has DSC support. Any DSC-
equipped mariner (on sea or land) within range can receive the call.
When the GPSMAP 376C is connected to a VHF with DSC support,
the GPSMAP 376C shows a call list, log, and a directory. Basic
wiring is required for the Garmin unit and VHF radio to send and
receive NMEA data from each other.
