AudioStar Operation
Fig. 40: The AudioStar Universe: The six primary categories listed in the Select Item menu of AudioStar.
It is important to understand that menu selections are set in a loop (Fig. 40). This means that pressing the Scroll Down key (Page 33, Fig. 39, 7) cycles down through all the available options within a given category, then returns to the first option. The Scroll Up key (Page 33, Fig. 39, 7) 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 four times or the Scroll Up key once.
The screen in Fig. 41 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.
2.Press the Scroll Down key once to display the “Event” option in the “Select Item” menu.
3.Press the ENTER key to choose the “Event” option and move down a level. “Event: Sunrise” is displayed.
4.Press the Scroll Down key once to display the “Sunset” option in the Event menu.
5.Press the ENTER key to choose the “Sunset” option and move down another level.
6.AudioStar calculates the Sunset time based on the current date, time, and location. AudioStar then displays the results of the calculation.
7.Press MODE once to start moving back up through the AudioStar levels. The first level up is the Event menu.
8.Press MODE again to move up another level. This is the top level, “Select Item”.
9.Press MODE again to return to the starting point of “Select Item: Object”.
