The manual I have shows two quite different circuit
board layouts. The schematic is probably the same.
The simple way is to cut and tape the White/Red wire
going from the power supply board to the backplane.
This carries the Emergency Power Alert tone to the
audio circuitry. The plug also has three other signals
on it: Ground (black), +9.6V (brn/blu) and A+ (org).
