Page 131: What Is Waas
SBAS system should be capable of providing your GPS unit with increased accuracy at any location in the world. Currently, enabling WAAS on your Garmin GPSMAP 376C in regions that are not supported by ground stations may not improve accuracy, even when receiving signals from an SBAS satellite.
Page 132: Loran Td Setup
The LORAN TD (Time Delay) feature eases the transition from using LORAN to using GPS. The GPSMAP unit automatically converts GPS coordinates to LORAN TDs for those who have a collection of LORAN ﬁxes for favorite ﬁshing spots and other waypoints recorded as TDs.

Page 134: Map Datums And Location Formats
Every chart has a map datum reference, and you can set the GPSMAP 376C to match most of those commonly used. If you are navigating and comparing the GPS coordinates to a map, chart, or other reference, set the map datum in the GPS unit to the same datum as the map to ensure the most accurate navigation.
Page 135: Digital Selective Calling (Dsc)
Coast Guard when used in an emergency distress call. To obtain a MMSI number, users must register their VHF radio with the FCC (Form 605). Garmin does not supply this number! For more information regarding MMSI numbers, visit navcen.uscg.gov/marcomms/gmdss/mmsi.htm.

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 GPS unit displays 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.
