In the R-390, I notice that for the 16-32 MC CAM, when the others are in alignment and the lines can be seen through the holes for those, the line for this cam is hidden by the 8-16 MC CAM underneath it. I don't see how that could be visible and presume it's normal but wondering how one is supposed to align the 16-32 MC CAM properly. Thanks, Barry - N4BUQ
