Carefully hold the outer edge of the Mystery Control dial and using thumb and forefinger of other hand, gently turn the center domed dial portion COUNTER-clockwise, just like loosening a screw. That domed piece in the center has an embedded machine scew in it that holds the whole dial to the gear shaft.
