I use 1.2 for one satellite only, and prior to finding that one, never used it at all, so I may be mistaken, but, I thought that the 1.2 positions were stored in the motor.
Also, I did have a problem one time, while searching for that one satellite, whereby I managed to hose my USALS aiming by modifying the 1.2 positions. I think I stupidly modified the "0" position instead of picking another number. Anyway, the cure was to switch back to USALS, go into the aiming screen, and select the "go to reference" option. This never did exit the "please wait for moving" screen (typical Openbox stupidity), but after the dish quit moving, I hit the exit key, cycled power on the receiver, and it worked properly again.
