The miter was off on the postive stop settings. 0 degrees was offabout 3/4 of a degree. There is no way, that I could determine,how to correct this problem. So I had to send it back. Apparentlythis is not an isolated issue. In the owner's manual was an insertthat states if this happens with the digital readout model, thenreset the miter read out. Of course the positive stops still exitswith the incorrect settings so I don't know what you are suppose todo. I guess the positive stops become not usable.
