With a spare piece of resistor leads, install a jumper across each of the TWO sets of jumpers
marked "9V". You will probably need to hold them in place with some paper masking tape
before you solder. Turn the board over, solder the jumpers in place, and trim the excess leads.
Now, install the regulator in its spot on the board next to the two jumpers, making sure that it
lines up with the outline silk-screened on the board. Hold it in place with some tape, turn the
board over, and solder the regulator to the pads. Trim the excess leads.
