This Instruction Manual begins by explaining the operation of
Autostar in sequence from turning on power to locating the first
object in the sky. The telescope and manual should be used together
to complete this important series of operations. The balance of the
manual is a reference for additional functions.
The first time Autostar power is applied, additional activities are
required. Pick a comfortable location and take the time necessary to
read each step carefully. When viewing is required, move to an open
area outside and continue operation.
First Operation
Autostar Installation: Verify that power is turned off at the
telescope computer control panel. Plug the coil cord (13) into the coil
cord port (11). Plug the other end into the computer control panel
HBX (handbox) port. Turn on the telescope power using the switch
on the ETX computer control panel or by plugging in the power cord
to the DS computer control panel.
Initialization: With power on, Autostar begins the startup process by
displaying the Meade copyright message, sounding a beep, and
initializing the computer system. After initialization, Autostar requests
information needed to operate the telescope.
*Problem* If Autostar does not display messages, turn the power off
and then back on. Also, check the batteries or other power source.
If the beep sounded and the screen is difficult to read, press MODE
(3) and Autostar resets the screen to factory settings.
Language Selection: Autostar offers text in one of six possible
languages. Press the key for the desired language.
*Problem* If the wrong language is selected, press MODE and
Autostar requests the language selection again.
Sun Warning: Autostar displays a sun warning message which must
be carefully read by every person using the telescope. After reading
the message, follow the instructions to move to the next operation.
*Hint* If screen messages are moving too fast (or slow), use the
SCROLL keys (8 & 9) to change the speed.
Self Calibration: “Testing Motors” is displayed and the telescope
moves a short distance in both axes. Automatic calibration of the
motors happens only once, the first time Autostar is used.
NOTE: If Autostar is moved to another telescope, it needs to be
recalibrated (see the Setup:Telescope:Calibrate Motor menu).
Getting Started: “Getting Started,” is displayed with a message
offering a description of Autostar operation. Press ENTER (2) to
bypass this tutorial or press the “?” key (10) to begin the message.
At this point, Autostar can move the telescope using the ARROW
keys (5). Pressing one of these keys moves the telescope up, down,
left, or right. The speed of movement is changed by pressing a
NUMBER key (9 = fastest, 1 = slowest).
Date: The date must be entered each time power is applied. Enter
numbers by pressing the numeric keys. Press the right or left
ARROW key (5) to move the cursor. To change the month, use the
up or down ARROW key. After the correct month is displayed press
the right ARROW key to move to the year. Change the year, if
required, using the numeric keys. When the correct date is
displayed, press ENTER to complete the date entry.
*Hint* The utility light (14) is turned on during date and time entry to
illuminate a watch.
Time: Local time must be entered each time Autostar power is
applied. Enter the time using the NUMBER and ARROW keys.
Change AM or PM using the SCROLL keys (8 & 9). When the time
displayed is correct, press ENTER to start the clock running.
