Map Datum
This option allows you to define a primary map datum,
and also a secondary map datum if you need one.
A map datum is a geographic reference that ProMark3 will
refer to to calculate the coordinates of your position.
ProMark3 holds more than 70 different map datums in its
memory.
After selecting the Map Datum option from the Setup
menu, tap the map datum that applies to your country and
working area.
To enter a user map datum, select the term “USER” in the
list of datums arranged in alphabetical order. Then, for
more information on how to enter a user map datum, refer
to the appendix at the end of this manual (page
194).
Time Format
This option allows you to select the time format you want
to use in ProMark3. You can choose from three different
time formats: Local 24Hrs, Local AM/PM or UTC.
After selecting the Time Format option from the Setup
menu, just tap the time format you want to use.
