Beseler computerized color head

Does anyone know how to adjust the knobs on the Beseler dichro 45 computerized color head. I picked one up from someone and it's been tricky to say the least. I have the D.A.T.A. module that goes with it. Can I use the enlarger separately from the data module?

On a separate note, does anyone have the D.A.T.A. module manual? I have one for the colorhead, but it hasn't been real helpful.

Thanks !
