with a short pause at each location. Press ENTER to start the survey. While a slew is

Sleep Scope is a power saving option that shuts down Autostar and the telescope
without forgetting its alignment. With "Sleep Scope" selected, press ENTER to acti-
vate 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 ses-
sions. 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 telescope to move to its pre-determined Park position.
Once parked, the screen prompts to turn off power.
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.
Cord Wrap 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. This menu is set to "On" and cannot be
changed by the user.
