Fig. 19: 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. 20). 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 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.

Audiostar 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.

NOTE: To perform an accurate calculation, Audiostar must be properly initialized with the current date, time, and location of the observing site. To enter the current date, time, and location information of your observing site, see INITIALIZING AUDIOSTAR, page 16, before proceeding with this exercise.

Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
