The procedure is as follows: 1) Remove the jumper wire (JW) from the R467, and instead, mount a 27K resistor. 2) Remove the chip jumper wire (JR) from the R468, and instead, mount a 27K resistor. 3) Remove the JR209 27K resister, and instead, connect a chip jumper wire (JR). 4) Remove the JW219 27K resister, and instead, connect a jumper wire (JW). Use either suitable lead wires or conductors as the jumper wires.
