I just disabled local control on two SR227's today (16 July 2006) and verified that this
To disable local control on the SR227-C Supersocket, remove the 2 screws from the back of the
socket that enables one to remove the back cover, sliding the black and white wires through the
holes as the back cover is removed. The jumper for pin 7 of the 78570 IC is the small jumper
closest to the RF can transformer and pin 1 of the IC on the component side of the PC board.
Cut it and local control is disabled. The only other jumper on the component side of this PC
board is close to pins 16 and 17 on the other side of the IC close to where a smaller gauge
black wire comes out of the PC board in an area with lots of real estate. Do not cut this one.
Replace the back cover and the 2 screws holding it on and you're done!
