Initialization is a pro- cedure that ensures that Autostar oper- ates correctly. When you first use Autostar, it doesn't yet know where the observa- tion location site is or the time or date of the observation ses- sion.

During the procedure, you will enter infor- mation, such as the current time and date, observation location, and telescope model. Autostar uses this information to pre- cisely calculate the location of celestial objects (such as stars and planets) and how to move your tele- scope correctly for various operations.

Moving Through Autostar’s Menus

The Autostar database is organized in levels for quick and easy navigation.

•Press ENTER to go deeper into Autostar's menu levels.

•Press MODE to move back toward the top menu level.

•Press the Scroll keys to move up and down through the options available for each level.

•Press the Arrow keys to enter characters and digits.

The Arrow keys are also used to move the telescope.

Initializing Autostar

This section describes how to initialize Autostar. Perform this procedure the first time you use Autostar or after performing a RESET. An example of this procedure is presented in "APPENDIX E," page 36.

1.Make sure that the vertical and horizontal locks (6 and 9, Fig. 1) are secured as described on page 5.

2.Verify that Autostar is properly connected to your telescope. See “HOW TO ASSEMBLE YOUR TELESCOPE,” page 10.

3.Flip the telescope power switch to the ON position.

The Autostar screen is activated and a copyright message displays briefly, followed by a short beep. Then Autostar takes a few moments to start up the system.

4.A message displays that warns not to look at the Sun. At the end of this message, press the Speed/? key to signify that the message has been read and understood.

5.The Getting Started menu displays a scrolling message with two choices:

a.Hold down the Speed/? key (8, Fig. 3) for information on Autostar functions and controls. When finished, press MODE (3, Fig. 3) to exit Help and to return to the Getting Started pro- cedure, or,

b.Press ENTER (2, Fig. 3) to bypass the Help tutorial and continue with initialization.

6.Autostar then requests the current date. Use the Up and Down Arrow keys (5, Fig. 3) to enter the digits for the date. Use the Right Arrow key (5, Fig. 3) to move from one number to the next in the day display, and also to move to the month. Then, use the Scroll keys (6 and 7, Fig. 3) to cycle through the list of months.

When the current month is displayed, use the Right Arrow (5, Fig. 3) to move to the year. Use the Up and Down Arrow keys to enter all four digits of the current year. Press ENTER when the date has been entered.

7.Autostar then requests the current time. Use the Up and Down Arrow keys to enter the time. (Use a "0" for the first digit if less than 10.) Use the Right (or Left) Arrow key to move from one number to the next. Press one of the Arrow keys (5, Fig. 3) to scroll to "AM" or "PM." If you select the "blank" choice that follows "AM" and "PM," the clock displays time in a 24-hour (military time) format. Then, press ENTER to start the clock.

NOTE: When multiple choices are available within a menu option, the current option is usually displayed first and highlighted by a right pointing Arrow (>).

8.The next screen requests the status of Daylight Savings Time. Pressing a Scroll key tog- gles between the YES/NO settings. Select the desired setting by pressing ENTER.

NOTE: Daylight Savings Time may be referred to by a different name in various areas of the world.

9.The next screen asks for the Country or State (listed alphabetically) of the observing site. Use the Scroll keys to cycle through the database of countries, states, and provinces. Press ENTER when the correct location displays.

10.The next screen asks for the city (listed alphabetically) closest to the observing site. Use the Scroll keys to cycle through the database of cities. Press ENTER when the correct city appears on screen.

11.The next screen asks for the telescope model. Use the Scroll keys to locate ETX-60 or ETX-70. Press ENTER to select the appropriate model.

12.System initialization is complete and the screen reads "Setup: Align".
