tajima tmfx D + POWERUP Option\ Centering Needles

Can someone tell me how the D + POWER UP Color change potentiometer settings works once you get into it? I haven't done it yet and can't find any info on the options.

I am trying to center my needles over the needle plate holes. I have removed the color change mechanism and reinstalled, I can set the machine on 100 and turn the color change wheel to a spot that isn't quite centered to the needle hole and will move from 1-12 on manual color change. When I try to set it perfectly centered over holes set on 100 and do a ATH I get 383 error. will the potentiometer settings menu reset where the needle starts over the holes once I have them lined up?

Also are there any Tajima repair techs for hire that do tech phone calls to walk me though this?

Thanks for the help
