I'm using a Tech4, MRC 220 controller, DC, and wanted to ask about the graduations and numbers around the control knob. I have to have the power turned up to between 20 and 30 before anything starts to move. Is this pretty much normal, or do I have dirty track, even tho I clean it frequently?
Also, the controller has a "brake"button on it. Doesn't seem to do anything when I push on it. What is it's purpose? Iv'e misplaced the sheet that came with the controller, so I'm asking for some advice. Thanks---John R
