HAND CONTROL OPERATION

INITIAL SETUP

1.

 Make sure the mount is level to the ground.

2.

 Point the telescope roughly to one or a group of visible bright stars in the sky.

3.

 Connect the hand control to the mount with the provided cable. For autoTracking 

telescopes, plug the DC12 volt power into the outlet of the mount to turn on the pow-
er. For Multi-function telescopes simply flip the power switch to the “on” position.

4.

 the initial screen displayed on the hand control is the Version screen. Press ENTER 

to proceed.

5.

 The hand control will display a warning concerning pointing of telescope at the sun 

without proper equipment. If you have read the message already, pressing ESC will 
bypass the message and skip to the next step.
The hand control’s red light will become dimmer and the backlight of the key pads 
will turn off if idle for 30 seconds. Pressing any key turns it back on.

6.

 Enter the telescope’s current latitudinal and longitudinal position using the numeric 

keypad. First enter the longitudinal coordinate, followed by the latitudinal coordinate. 
Use the scroll keys to choose between W or E, and N or S. Pressing the left or right 
directional keys will move the cursor to the previous or next number. Press ENTER to 
confirm. The format you enter should look like this: 123 04’W 49 09’N.

7.

 Enter your current time zone in hours and minutes (see Appendix C) using the scroll 

keys and numeric key pad (+ for East - for West). Press ENTER to confirm. The format 
you enter should look like this if you are in Pacific Standard Time (PST): -08:00

8. 

Enter  the  date  in  the  following  format  mm/dd/yyyy  using  the  numeric  keypad. 

Press ENTER to confirm.

9.

 Enter your current local time using the 24ht time mode (e.g. 2:00PM=14:00). Press 

ENTER to view the time you just entered. If it is incorrect, press ESC to go back to 
the previous screen. If correct, press ENTER again to proceed to the daylight saving
