Units Setup Page
The Units features are best used by individuals with a
working knowledge of map grids and datums. To learn
more about these subjects, visit the National Imagery and
Mapping Agency at http://www.nima.
mil or inquire at your local library.
To access the Units Setup
page:
1. Press the Page/Quit button or
the Main Page button to open
the Main Menu.
2. In the Main Menu, scroll down
and select Setup.
3. Select the Units icon to open the Units Setup
page.
Position Format—Allows you to choose from different
grid formats. The default position format, ‘hddd°mm.
mmm’ displays the latitude and longitude in degrees and
minutes and is most commonly used.
LORAN TD 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 always
references the LORAN chain
number and secondary stations
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 reflects those changes. Because the unit
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.
To adjust the settings, select Loran TD as the Position
Format to open the Loran TD setup window. To change
the settings of any fields, highlight the field, press the
Thumb Stick In. When done, highlight Save and press In.
