I am a relatively new Flex 5000C user. Very satisfied. ANF works great but I can't seem to get TNF to work. Yes I have read the eight page "white paper". Any advice? Looking for step by step "TNF for dummies" level info here
Yup that is precisely what I do. TNF button ights up when I click. TNF+ lights up but only as long as I hold mouse button down then it goes out. See no change in display when I hit TNF+; the eight page white paper says TNF+ button should result in a new notch showing on screen which I can control (depth and width). I must be missing and intermediate step?
