SETUP
If you prefer, you can enter and save up to five user-entered grids. User-
entered grids are non-standard grids that are used in relatively small
operational areas, in areas where grid systems are locally prescribed, and in
areas that are not directly supported by any of the built-in coordinate
systems. A user-defined grid can also be used to increase the accuracy of
position data that is collected in an area that is more accurately described by
a local grid. The user-defined grid utility can also be used to input State Plane
Coordinate Systems. Parameter tables for these inputs are provided in
Appendix 12.
A number of options are available when entering a user-defined grid. Refer
as necessary to Table 4-1 while entering a grid.

To enter a user-defined grid, access SETUP 8 and use the RIGHT ARROW
to scroll through the coordinate systems. Stop when an empty user grid
is displayed and press ENTER.
Key in any grid name up to 16 characters long and press ENTER. Press
the RIGHT ARROW to select the mapping function or projection
(transverse mercator, lambert conical, stereographic, oblique mercator,
or polyconic). Press ENTER when the desired function/projection is
displayed.
