Press the reset button when your in the centre of the area you want to monitor ( the centre point ), move away from the centre
point. As you move further from the centre point the latitude, longitude values will begin to change. Stop moving when you get to
the boundary of the area you want to monitor.
Observe the latitude difference and the longitude difference, use the highest of the two values for the IFMOVE value.
The boundary test can also determine the accuracy of the GPS receiver. When you press the reset button the latitude difference
and the longitude difference values should only increase if you start moving.
an inaccuracy is the amount the values change from zero, when you have not moved. This inaccuracy should be taken into account
when selecting a value for the ifmove command.
The boundary test can also be used to mark your current position. This can be useful if you move away from a particular location
and you want to be able to go back to that exact location. E.g. on a beach or in a forest.
