Showing position
coordinates
You can display position coordinates on the
CHART
screen as:
• lat/lon coordinates from the GPS receiver
• Phantom loran TDs that are calculated from the GPS
coordinates (for when you’d like to see your position
mathematically converted to and displayed in loran TDs)
To set up your
CHART
screen to display position coordinates
as loran TDs in addition to lat/lon, see “Changing the chart
setup” starting on page 13-24.
To show your position coordinates and other navigational data
on the
CHART
screen, press either of the two
INFO
keys (the
second
INFO
key will appear only after you press the
INFO
key
at the bottom of the screen): Several forms of numeric
navigational data appear—in large, easy-to-read numbers—at
the bottom of the screen in an
INFO BAR
.
