currently selected in the Setup TD field. If you enter a

different LORAN chain number, change the secondary

stations or offsets in the Setup TD field, the active

waypoint information will reflect those changes. Since

the GPSMAP 76 does not rely on the LORAN signal

for navigation, it can reference a different GRI chain

and/or secondary stations and still navigate to the

location stored in memory.
The Location Format field is accessed in the Main

Menu under the Setup option’s Location tab. The

‘LORAN TD Setup’ window contains the fields to

select the Loran GRI-Chain Number, Primary and

Secondary Stations, and TD Offsets.
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 displayed 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 76 converts the

TD coordinate to a LAT/LON coordinate before storing

a waypoint to memory. The unit can navigate to a

converted TD coordinate anywhere in the world.
