Garmin GPSMAP 76S - Manual (Page 67)

The Location Format field is located under the Setup—Location tab in the
Main Menu. The ‘LORAN TD Setup’ window contains the fields to select the
Loran GRI-Chain Number, Primary and Secondary Stations, and TD Offsets.
To setup Loran TD from the Main Menu:
1. Using the ROCKER, highlight the “Location Format” field on the ‘Location
Tab” and press ENTER.
2. Highlight ‘Loran TD’, press ENTER. This will display the LORAN TD Setup
window.
3. To change the settings of any of the five fields, highlight the field, press
ENTER, select/enter the desired setting then press ENTER.
4. When done, press the PAGE Key to return to the Main Menu.
If the active GRI Chain, Secondary Stations or Offsets are changed, all
waypoints stored in the units memory will update and reference the the new
settings when displayed as a LORAN TD. It is important to note that the saved
coordinates of the waypoint are not being modified, they are only being dis-
played in reference to the different GRI Chain, Secondary Stations or Offsets.
Remember that the GPS is not relying on the LORAN signal for navigation. The
GPSMAP 76S converts the TD coordinate to a LAT/LON coordinate before storing
a waypoint to memory. Because of this the unit can navigate to a converted TD
coordinate anywhere in the world.
