Meade LXD75 Gebrauchsanleitung

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

Fig. 19). 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 (

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 demon-
strates 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. 20 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.

To demonstrate how the Autostar menu structure works, the following exercise calcu-
lates 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.
