SNE V VTA adjustment

Hi,

New to the forum!

I need help with downward VTA adjust on my SME V.

According to the manual you have to screw in the VTA screw until you feel resistance, no problem.

To raise the arm you keep turning clockwise, no problem.

But to lower the arm you turn the screw anti clockwise but all that does is undo the VTA screw! I must be missing something somewhere!

I have read on the forum that you need to release a clamp to do the fine adjustment but there is no mention of that in the manual and I'm not sure which clamp.

Any help gratefully received!

Cheers.
