hi Damon
the red line is same thickness at all points
It has a button labled digital array.
I was under the impression that there is a nine point digital array adjustment
What i need to know is there a nine point digital array adjust on this chassis
or not
DP15E
I just finished reading kevin's post and his had this feature
does anyone have # to call Hitachi Tech Assist
