Brightness Adj: Adjusts the brightness of the display using the Scroll keys. When complete, press
ENTER.
Contrast Adj: Adjusts the contrast of the display using the Scroll keys. When complete, press
ENTER.
Beep: Turns the beep on or off.
Sleep Scope is a power saving option that shuts down Autostar and the telescope without for-
getting its alignment. With "Sleep Scope" selected, press ENTER to activate the Sleep function.
Autostar goes dark, but the internal clock keeps running. Press any key, except ENTER, to re-
activate Autostar and the telescope.
Park Scope is designed for a telescope that is not moved between observing sessions. Align
the telescope one time, then use this function to park the telescope. Next time it is powered up,
enter the correct date and time – no alignment is required. Pressing ENTER causes the tele-
scope to move to its pre-determined Park position. Once parked, the screen prompts to turn off
power.
Cord Wrap, when set to "On," moves the telescope in such a way as to prevent the cords and
cables attached to your telescope assembly from getting wound around the assembly and tan-
gled as the telescope slews to objects. "Off" is the default setting.

Setup Menu

The Setup menu's primary function is to align the telescope (see
17). However, there are numerous other features available within the Setup menu, including:
Date changes the date used by Autostar. This function is useful to check events in the past or
future. For example, set the Date menu for a day three months in the future. Then check the
"Select Item: Event" menu for the Sunset time on that date. See
Time changes the time entered into Autostar. Setting the correct time is critical for Autostar to
properly calculate locations and events. Time may be set to 24-hour mode (military time) by
selecting the "blank" option which follows the "AM" and "PM" options.
Note: The time and
Daylight Saving is used to enable or disable Daylight Savings time.

Sun Warning: Turns the "Sun Warning" message on or off.
Getting Started: Turns the "Getting Started" message on or off.
NOTE: This feature is usually only required in very cold weather.
IMPORTANT NOTE: When the "Park Scope" option is chosen and the display
prompts you to turn off the telescope's power, Autostar is unable to be returned to
operation without turning the power off and then back on.
NOTE: Daylight Savings Time may be referred to by different names in various areas
of the world. Check local time to verify.
Model: Allows you to select the telescope model connected to Autostar.
Focal Length: Displays the focal length of the selected telescope.
Az Ratio and Alt Ratio: The Az (Azimuth) ratio and Alt (Altitude) ratio refers to the gears
of the telescope's motors. Do not alter these numbers.
Az Percent: The Az (Azimuth) Percent allows you to change the azimuth backlash, i.e., the
way the Arrow keys move the telescope along the azimuth (horizontal) axis. If you enter a
value near 100, the telescope tube responds more quickly (it responds immediately at
100%) as you hold down an Arrow key and also slews (moves) the tube more quickly. If
you enter a value near 0, it takes longer for the tube to respond as you hold down an Arrow
key and also slews the tube more slowly. Experiment with this option. Try changing the per-
cent value until you get a "feel" for the Arrow keys that is comfortable for you.
Alt Percent: The Alt (Altitude) Percent operates identical to the AZ Percent option (see
above), but allows you to change the altitude backlash, i.e., the way the Arrow keys move
the telescope when moving along the altitude (vertical) axis.
