A little help with MRA x-creen Sport, please

[BadNews]

I've installed it on my stock screen. How do you adjust it? The instructions say something about releasing the "rotary knob" for adjusting. Do you turn it to release, or just pull it back out? I don't want to break the knob. The knobs in question are right in front of my fingertips in the photo:

Thanks in advance!

You turn those levers 90-degrees. That will loosen the pivot adjustment allowing you to move the screen or arms to whatever angle you wish.
Turn the levers back 90-degrees to locked position to hold the arms or the screen in place.
Yours are shown in the "unlocked" position I believe?
You should feel the levers get easier to move toward the unlocked position, and a bit harder to move toward the locked position.

I have a "knock-off" version of that extension, and the levers hold it in place pretty well, even over 100mph.

Thanks! That worked! Yes, they are unlocked in the photo above. I turned them 90* as suggested and I could feel the 'rotary knob' lock into place, and it prevented me from being able to move the spoiler or levers until I unlocked them.
Thanks again!
