These 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 library.
General Settings Tab 
GPS Mode - Allows you select Normal GPS operation for navigation 
and position reporting, Battery Saver which slows the satellite updating 
process to save power, Simulate GPS to save power and yet use GPS 
features to plan routes, etc. and GPS Off for maximum power savings.
Location Format - Allows you to choose from different grid formats. 
The default location format ‘hddd
o
mm.mmm’ displays the latitude and 
longitude in degrees and minutes and is the one most commonly used. 
Selecting a location format will cause the map datum to match that  format.
Map Datum - Offers a selection of nearly all map datums in common 
use.  Every map is based on a map datum (a reference model of the 
earth’s shape) and is usually listed in the title block of the map.  If you 
are comparing GPS coordinates to a paper map, chart, or other refer-
ence, the map datum in this field must match the horizontal map datum 
used to generate the map or other reference.  The default datum is WGS 
84 (World Geodetic Survey 1984) and should only be changed when 
using maps or charts specifying a different datum.  If a map does not 
specify a datum, use the list to find datums applicable to the region of 
the map, select the one that provides the best positioning at a known 
point.  You may also choose the ‘User’ datum for custom designed grids.
Enable/Disable and Clear Track Log - As you move about the unit 
creates an automatic track log of your movements which can be viewed for 
later reference when saved to MapSource. The ‘CLEAR’ button, allows you 
to record a new track logs when the current log is full.
