How to Verify Datum

Datum is used to select between different models of the earth. It is essential that you use datum in a consistent way.
If you use paper charts together with electronic chart material, it is recommended that you use the same datum as
your current paper chart to avoid misalignment between your electronic chart system and points taken or plotted on
your current paper chart.
Once you have selected a datum,
all numerical latitude-longitude
position values are presented in
your selected datum.
To change the datum:
1. Select the datum indication in the top box in the information area.
2. Spin the scrollwheel to select appropriate datum, the one that matches your paper charts, then push the
scrollwheel.
Note: ARCS raster charts contain some rasterized position information, like scale bars on PA paper charts, which is
true only if you have selected native datum of that ARCS chart.
