will activate the cursor in the GPS window (indicated by highlighted
characters in a GPS window field). It is used to highlight fields for data
entry, changing information or cycling through available options. Pressing a
third time will deactivate the cursor.

or move through data fields.

cannot fit on the screen all at once.

This manual will describe entering data using
the K and O knobs. Experiment with them and
become efficient in entering data with the concen-
tric knobs. This will greatly reduce the amount of
time required to navigate with the GNC 300XL.
Whenever the GNC 300XL is displaying a list
of information that is too long for the display
screen, the scrolling arrow prompt will indicate
which direction to scroll to view additional infor-
mation. To scroll through a list (with the cursor
active), simply rotate the inner knob. When the
cursor in not active, use the outer knob to view
additional information.
