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 GPSMAP 76CSx 
is not relying on the LORAN signal for navigation 
and actually converts the TD coordinate to a useful 
latitude and longitude 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.
You must know your GRI chain number and 
secondary stations to create a LORAN TD position.
