Garmin GPS 72 - Manual (Page 60)

The LORAN Position Format fi eld is located under the Units tab in the Main Menu.
The ‘LORAN TD Setup’ window contains the fi elds 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” fi eld on the ‘Location Tab” and
press ENTER.
2. Highlight ‘Loran TD’, press ENTER.
3. To change the settings of any of the fi ve fi elds, highlight the fi eld, 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 have been changed since the
waypoint was created, the waypoint will now reference the active GRI-chain and secondary
stations and adjust the TD coordinates accordingly. Remember that the GPS is not relying
on the LORAN signal for navigation and actually converts the TD coordinate to a useful
LAT/LON coordinate before storing the waypoint to memory or using it for navigation.
Because of this the unit can navigate to a TD coordinate anywhere in the world.
