The user-defined datum option allows
you to custom-tailor a datum reference
fixim which all position coordinates are
calculated. All entries are defined as
differences finm the WGS 84 standard
datum. CAUTION; Selection and use of
the user datum fimction is for individuals
experienced in the use of map datums.
If the pre-defined map datums do not
correspond to the chart you are using and you are unsure of the correct
