1.5 Operation Using the On-Screen Boxes
All radar functions can be accessed by using the trackball alone. This is done by
choosing the appropriate on-screen box with the trackball and operating the
trackball module to choose item and option. (See paragraph 1.9 for location of all
on-screen boxes.) On-screen boxes come in two varieties: Function selection
and function selection w/pop-up menu. On-screen boxes of the latter type have
“
► ” at the right side of their boxes, as in the MARK box shown below.
To operate the radar using on-screen boxes, do the following:
1. Roll the trackball to place the trackball marker inside the box desired.
Note: The trackball marker changes its configuration according to its location.
It is an arrow when placed outside the effective display and a cursor
(+) when inside the effective display. See the illustration on the next
page for further details.
For example, choose the MARK box, which is at the bottom left corner.

MARK box
When a box is correctly selected, its color changes from green to yellow
(default colors) and the guidance box at the bottom right corner shows
operational guidance. The operational guidance shows the function of the
left and right buttons, with a diagonal line separating the information. For the
MARK box, for example, the operational guidance is “MARK SELECT /
MARK MENU.” In this case you would push the left button to choose a mark
or push the right button to open the MARK menu.
