AudioStar Operation

Fig. 20: The AudioStar Universe: The six primary cate-
gories listed in the Select Item menu of AudioStar.
It is important to understand that menu selections are
set in a loop (Fig. 21). This means that pressing the
Scroll Down key (Pg. 22, Fig. 19a, 7) cycles down
through all the available options within a given category,
22, Fig. 19a, 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. 19a 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 AudioStar 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".

AudioStar Navigation Exercise

To demonstrate how the AudioStar menu structure
works, the following exercise calculates Sunset time
so an evening observing session can be planned.
To Calculate Sunset time:
1. Press the MODE key several times, until "Select
Item: Object" is displayed.
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
