Nikon D1 custom settings

I have a D1 with I think the original 1.03 firmware. The shutter and aperture command dial are swapped.
What do I have to do to get the back dial back to being used for the shutter, then the front dial by the lens for the aperture?

It's all in the manual, if you haven't got a manual you can download it here

It's option 12 in the set-up menu (page 69)
