Locate the "volume" and "set" buttons on the pcb (compare with the labels on the outside of the feeder enclosure).  Remove the tape and small circular metal covering from these buttons (figure 2).  You will see two exposed traces on each button.  Each outer trace has two holes drilled in it (see figure 1).  Drill two additional holes in the pcb, one in each of the inner circular button traces (figure 3).
