Hibernate - Hibernate allows the NexStar to be completely powered down and still retain its alignment when turned back on. This not only saves power, but is ideal for those that have their telescopes permanently mounted or leave their telescope in one location for long periods of time. To place your telescope in Hibernate mode:

1.Select Hibernate from the Utility Menu.

2.Move the telescope to a desired position and press ENTER.

3.Power off the telescope. Remember to never move your telescope manually while in Hibernate mode. Once the telescope is powered on again the display will read Wake Up. After pressing Enter you have the option of scrolling through the time/site information to update the current setting. Press UNDO to edit the current setting and enter the correct time and date. If you are using the CN16 GPS accessory, the GPS receiver will automatically download the current date and time to the telescope.

Pressing UNDO at the Wake Up screen allows you to explore many of the features of the hand control without waking the telescope up from hibernate mode. To wake up the telescope after UNDO has been pressed, select Hibernate from the Utility menu and press ENTER. Do not use the direction buttons to move the telescope while in hibernate mode.
