To configure a map fix:
To use this format, you need to follow these steps in order. First, take your
map of the area and determine a reference latitude/longitude. (Please note
that in order for this system to work, the latitude/longitude lines must be
parallel with the edge of the map. USGS maps are parallel, others may not
be. Also, this works better with smaller scale maps.) The reference position
can be anywhere on the map, but the closer it is to your location, the smaller
the numbers you'll have to manipulate.
Once you've decided on a reference position, you can save it as a waypoint.
See the waypoint section for information on saving a waypoint. Save the
reference position as a waypoint. Exit from the waypoint screens.
1. Press
MENU|MENU|↓ to GPS SETUP|ENT.
2. Press ↓ to
COORDINATE SYSTEM|ENT.
3. Press ↓ to
SETUP MAP FIX|ENT.
The following screen appears, and
MAP SCALE is highlighted. Press ENT and
enter the map's scale. This is generally at the bottom of the paper map. It's
shown as a ratio, for example 1:24000. Press
EXIT and the unit returns to
the Configure Map Fix screen.
Configure a map fix so the unit can find your position on a printed
chart or topographical map.
Press ↓ to SELECT ORIGIN |ENT. Press → |ENT, then ↓ or ↑ |ENT to choose a saved
waypoint. Select the waypoint you saved the reference point under and press
ENT. The unit displays a waypoint information screen with the command SET AS
ORIGIN selected; press ENT and the unit returns to the Configure Map Fix menu.
Finally, press
EXIT to close this menu. Now press ↑ to COORDINATE SYSTEM|ENT,
select
MAP FIX from the list and press ENT|EXIT|EXIT|EXIT. All position
information now shows as a distance from the reference point you chose.
