Loran TD Setup
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 ARROW KEYPAD, highlight the ‘Setup tab, then press RIGHT to highlight the ‘Units’ sub-
menu tab. Highlight the “Position Format” field and press ENTER. You may also press MENU from
the “Units” tab to display the ‘Loran TD On’ option. (If you use ‘Loran TD On’, skip to step 3.)
2. Highlight ‘Loran TD’, press ENTER, then highlight ‘Setup’ and press ENTER.
3. To change the settings of any of the five fields, highlight the field, press ENTER, select/enter the
desired setting and press ENTER.
4. When done, press the QUIT 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 now references 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 (in the background) before storing
the waypoint to memory or using it for navigation. Because of this the unit can navigate to a TD coordi-
nate anywhere in the world.

book” from the Garmin web site.
