GPS

During your field operation, the GPS icon/button in the upper left-hand side of the Map

Screen should appear as green, which means you are receiving a differential GPS

signal. If this icon appears yellow, you are still receiving GPS but are not receiving a

differential signal. If it appears gray then you have lost GPS. In either case, you should

check your GPS settings.
