It is important to understand that menu selections are set in a loop (Fig. 16

This means

that pressing the Scroll Down key (7, Fig. 2) cycles down through all the available

options within a given category, then returns to the first option. The Scroll Up key (7,

Fig. 2) cycles up through the options in the opposite order. Note that this capability is a

quick way to get to an option that is near the bottom of the list. The following example

demonstrates this capability.

Example:

To navigate to the “Select Item: Setup” menu option when the “Select Item: Object”

menu is displayed:

1. Press the Scroll Down key five times or the Scroll Up key once.

The screen in Fig. 17 displays two lines of information. The top line shows the current

menu level. The second line displays an option which may be selected within that

menu level. Some options are choices that select the next menu level down. The

Scroll keys move up and down within the list of available options, showing one option

at a time.

When the desired option is displayed on the second line, press the ENTER key to

choose that option and move down one menu level.

Press the MODE key to leave a level; e.g., the wrong menu option is chosen.

Important Note: No matter how many levels into Autostar II are traveled,

each press of the MODE key moves up a level, until the top level, "Select

Item," is reached. Once in the Select Item level, press MODE to return to

the topmost level, "Select Item: Object."
