Note: If ENTER is pressed for two seconds or more and then released, Autostar emits a beep and “ENTER to Sync” is displayed. "ENTER to Sync" may be used only after your telescope has been aligned and is pointing at an object. See page 30 for more details.

3MODE Key: Press to return to the previous menu level. The top menu level is “Select Item." The MODE key is similar to the ESCAPE key on a computer.

Note: Pressing MODE repeatedly while in the “Select Item” level moves

Autostar to the topmost screen: “Select Item: Object.”

Note: If MODE is pressed and held for two seconds or more, information about the telescope's status displays. When the status displays, press the Scroll keys (7, Fig. 2) to display the following information and more:

■Right Ascension and Declination (astronomical) coordinates

■Altitude (vertical) and Azimuth (horizontal) coordinates

■Local Time and Local Sidereal Time (LST)

■Timer and Alarm Status

Press MODE again to return to the previous menu.

E GO TO Key: Press to slew (move) the telescope to the coordinates of the cur- rently selected object. While the telescope is slewing, the operation may be aborted at any time by pressing any key except GO TO. Pressing GO TO again resumes the slew to the object. Also, press GO TO after a slew is completed to activate a "spiral search."

F Arrow Keys: Press to slew the telescope in a specific direction (up, down, left, and right), at any one of nine different speeds. See SLEW SPEEDS, page 16.

G Number Keys: Press to input digits 0 to 9. When data is not being entered, the Number keys can be used to change the slew speed. To operate, just press a number key (1 is the slowest speed, 9 is the highest speed). Press the Number key "0" to turn on and off the red utility light on the top of the handbox.

H Scroll Keys: Press to access options within a selected menu. The menu is dis- played on the first line of the screen. Options in that menu are displayed, one at a time, on the second line. Press the Scroll keys to move through the options. Press and hold a Scroll key to move quickly through the options.

I ? Key: Press to access the "Help" function. Help provides on-screen information on how to accomplish whatever task is currently active.

Hold down the ? key and then follow the prompts on the display to access details of Autostar functions in the Help feature. The Help system is essentially an on- screen instruction manual.

If you have a question about an Autostar operation, e.g., INITIALIZATION, ALIGNMENT, etc., hold down the ? key and follow the directions that scroll on the second line. When satisfied with the Help provided, press MODE to return to the original screen and continue with the chosen procedure.

J Coil Cord Port: Plug one end of the Autostar coil cord (see 1)) into this port located at the bottom of the Autostar handbox and the other end into the HBX port of the computer control panel (A, Fig. 1e).

1) Coil Cord: Plug one end of the Autostar coil cord into the HBX port (A, Fig. 1e) of the computer control panel of the telescope and the other end into the Autostar coil cord port (See J).

1! RS232 Port: Plug in RS232 connections for downloading and connecting to com- puter. Useful for downloading the latest satellite data and software revisions directly from the Meade website (www.meade.com) Requires optional #505 AstroFinder™ Software and Cable Connector Kit. See OPTIONAL ACCESSORIES, page 38.

1@ Utility Light: Use this built-in red light to illuminate star charts and accessories without disturbing your eye's adaptation to darkness. Press "0" to turn the light on and off.
