There is no adjustable timing on a 400ex. Only a crank key.
Are you referring to setting the cam in time with the crank?

Set the crank to TDC, marked by a T on the fly wheel, then line up the marks on the cam sprocket level with the top of the head with the cam lobes facing down. You are now in time.

It is that simple and it can't be changed without changing the key on the crank.
