points to be displayed on the screen. This mode is best used after points
have been logged into the memory.

mapped. The maximum value is 26.56X15.93 and a minimum of
0.10X0.06 miles.

BOUNDARY: Allows the user to select a field currently in memory to
be used as the scale. This is useful when returning to a field that has

for an optimum scale to be set for the area to be covered.

to provide a more accurate reference for the map and also allows for
better usage of the available screen area.
