should be. Use the equatorial head latitude and azimuth adjustments to place Polaris in the center of the eyepiece.
Do not use the direction buttons to position Polaris. Once Polaris is centered in the eyepiece press ENTER; the
polar axis should then be pointed towards the North Celestial Pole.
Light Control – This feature allows you to turn off both the red key pad light and LCD display for daytime use to
conserve power and to help preserve your night vision.
Factory Settings – Returns the Advanced GT hand control to its original factory settings. Parameters such as
backlash compensation values, initial date and time, longitude/latitude along with slew and filter limits will be reset.
However, stored parameters such as user defined objects will remain saved even when Factory Settings is selected.
The hand control will ask you to press the "0" key before returning to the factory default setting.
Version - Selecting this option will allow you to see the current version number of the hand control, motor control
and GPS software (if using optional CN-16 GPS accessory). The first set of numbers indicate the hand control
software version. For the motor control, the hand control will display two sets of numbers; the first numbers are for
azimuth and the second set are for altitude. On the second line of the LCD, the GPS and serial bus versions are
displayed.
Get Alt-Az - Displays the relative altitude and azimuth for the current position of the telescope.
Goto Alt-Az - Allows you to enter a specific altitude and azimuth position and slew to it.
Hibernate - Hibernate allows the telescope 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 desire 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 confirm the current setting. Press ENTER to wake up 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.
Turn On/Off GPS
-
If using your Advanced GT telescope with the optional CN-16 GPS accessory (see Optional
Accessories section of the manual), you will need to turn the GPS on the first time you use the accessory. . If you
want to use the telescope's database to find the coordinates of a celestial object for a future or past dates you would
need to turn the GPS off in order to manually enter a time other than the present.
