Loran TD Position Format
When creating new waypoints using Loran TD coordinates you must set
the correct loran chain number and secondary stations 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 reflect those changes. Since
the GPSMAP 180 does not rely on the loran signal for navigation, it can
reference a different GRI chain and/or secondary stations and still navi-
gate to the location stored in memory.
To change the Setup TD settings:
1. Highlight the Setup TD field and press
