Setup
Align
Fig. 27b: Menu options display on
the second line. Use the Scroll keys
to move up or down through the list
of options. Press ENTER to select
the desired option.
Fig. 27a: Menus set in a loop.
It is important to understand that menu selections are set in a loop (
Fig. 27a
). This
means that pressing the Scroll Down key 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 five times or the Scroll Up key once.
The screen in
Fig. 27b
shows two lines of information in the AutoStar display. The top
line shows the current menu level. The second line displays an option which may be
selected. Some options are submenus that offer more choices. The Scroll keys move
up and down within the list of available options, showing one option at a time.
When an option is displayed on the second line, press the ENTER key to choose that
option.
Press the MODE key to return back to the last menu. This can be useful to exit a menu
or if the wrong menu option is chosen.
Important Note:
No matter how many levels into AutoStar are traveled,
each press of the MODE key moves up a level, until the top level, "Select
Item," is reached. Once Select Item displays, press MODE to return to the
topmost level, "Select Item: Object."
AutoStar Navigation Exercise
To demonstrate how the AutoStar menu structure works, the following exercise
calculates Sunset time so an evening observing session can be planned.
Note
To perform an accurate calculation, AutoStar MUST be properly ini-
tialized with the location of the observing site. See
INITIALIZING
AUTOSTAR
, page 19, before proceeding with this exercise.
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.
