I tried calling you just now to go over the settings, but your voicemail doesn't seem to be working properly. If you get a chance, give me a call and we'll go over the settings for the new PCB.

Hey Chris,
Per our conversation I first tried pushing the exercise switch for five seconds with the auto/manual switch in the off position. That did not change the rpm. Then, with the auto/manual switch in off, I pulled the F1 fuse and the harnesses from the controller and let it sit for an hour. I moved the dip switches back and forth then reset them in the correct position, th3n plugged harnesses back in, then put F1 fuse back in. After that I pushed the exercise switch for five seconds with the auto/manual switch in the off position. Unfortunately after all of this the unit still ran at the same lower rpm.
