The LORAN Position Format field is located under the Units 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” andpress ENTER.2. Highlight ‘Loran TD’, press ENTER.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 have been changed since thewaypoint was created, the waypoint will now reference the active GRI-chain and secondarystations and adjust the TD coordinates accordingly. Remember that the GPS is not relyingon the LORAN signal for navigation and actually converts the TD coordinate to a usefulLAT/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.IntroductionAppendix GLoran TD
