the left side of the unit are used to select pages and
enter data on the left side of the screen. Likewise, the
two concentric knobs and the CRSR button on the
right side of the unit are used to select pages and
enter data on the right side of the screen.
The cursor is an area of inverse video on the
screen. On many pages, data can be added, deleted,
or changed by first pressing the appropriate CRSR
button to turn the cursor function on and bring the
cursor on the screen. The appropriate knobs are then
used to enter the data. When a cursor is on the
screen, the page name normally shown in the left and
right lower segments is replaced with a CRSR
annunciation in inverse video.
a. Page Selection. The left outer knob is
rotated to select one of eight page types for the left
side of the screen. Refer to Table 3D-1.
The cursor function must be off.
Rotating the left outer knob one detent clockwise
or counterclockwise selects the page type marked on
the knob in that direction. Once the page type has
been selected with the left outer knob, the page
number is selected by rotating the left inner knob.
The right side operates in a similar manner. The
navigation pages are available on both sides. The
remainder of the page types are different. Refer to
Only the right inner knob has both an in and an
out position. With the knob pushed in, it works exactly
as the left inner knob. In the out position, it performs a
waypoint scan function. The usual position for the
right inner knob is the in position.
b. Waypoint Data Entry.
1. Press cursor to turn on the cursor function.
2. Rotate the outer knob to position the
cursor in the desired location. The
location will vary. Waypoint identifiers will
be in different places on the page
depending on the type page selected.
3. Rotate the inner knob to select the first
character of the waypoint identifier.
