Maybe other f5 owners could help me out. When I turn the threshold knob sometimes the number on the screen doesnt move. Other times it will say -9 until I get it cranked all the way around to the right, then it will change to 9. Sometimes it will move to another number and stay there no matter what I do with the knob. I dont understand how this thing works. If this isnt right then it has been like this since I received it a year ago. If this isnt right, what do I do? If it is broken,, is it possible to fix myself? If not, then what? Dont know it it matters but I bought it from Kellyco.
