IF THE DOME DOESN'T REMEMBER WHERE 'DOME HOME' IS:
- -Make sure dome and dome home are off:
4. Miscellaneous Menu
1. Set Switches
Dome NO
- -Manually set dome to South with handpaddle

- -Wait it out for about 10 minutes

IF THE TELESCOPE DOESN'T KNOW WHERE IT IS:
- -Turn tracking off:

3. Rates Menu
1. Set Track Rates
Set RA to 15.00 (hit ENTER for the rest)
- -Set telescope position in computer:
1. Initialization Menu
2. Set telescope position
MEAN RA: at zenith RA = Siderial Time (found on the left side of the screen 'S.T.__:__:__') Set RA approximately 15 seconds ahead of S.T.
DEC = 44o57'00''
EPOCH = Enter current year (example: May 2002 = 2002.4)
When S.T. catches up with the number entered for RA hit ENTER
- -Check to make sure it is set to zenith:
On monitor opper left, telescope HA should be 00.00.00 (or very close to it)
