Garmin GPS 48 - Manual (Page 64)

When creating new waypoints using Loran TD coordinates you
muset set the correct loran chain number and secondary sta-
tions in the Setup TD field before storing the waypoint. After
the waypoint is stored in unit memory, it will always reference
the loran chain number and secondary stations currently
selected in the Setup TD field. If you enter a different loran
chain number or change the secondary stations in the Setup
TD field, the active waypoint information will frflect those
changes. Since the GPS 48 does not rely on the loran signal for navigation, it can refer-
ence a different GRI chain and/or secondary stations and still navigate to the location
stored in memory.
To change the Setup TD settings:
1. Highlight the ‘Position Frmt’ field on the navigation setup menu, and press
E. Select LORAN TD, and press E.
2. Select the field to change, and press E.
3. Highlight the new setting, and press E.
