Different regions of the world use various models for lat/lon coordinates
on their charts, called "datum." You should always be sure that your
941X is using the same datum as your charts.
Press the STAR key until you display the USER CUSTOMIZATION
screen, then press the NAVIGATION OPTIONS menu key. Move the
cursor down to GEODETIC DATUM and press EDIT. Use the up or
down cursor keys to scroll through the list of datums (organized alpha-
betically, as in the list below). When you come to the datum you desire,
press ENTER, or press CLEAR to leave the datum choice unchanged and
exit the edit function.
The following chart lists the datums available in your 941X:
