To Configure A Map Fix - Lowrance LCX-112C Operation Instructions Manual

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.
