Bend the antenna ground tab fully up from the board. Carefully lift the board, unplugging the black connector at its base, and lay the board out of the way on its bundle of colored wires. The scanner would indeed program the new frequency limits, but would not pick up anything in that band. I later discovered that I would have to re-align the receiver to pick up anything. Just beware of the possible problems of restoring the 51-88 band.
