cated by other external switching devices to fa-
cilitate remote operation in conjunction with other
devices in a larger semi-automated system.
CAUTION
Never apply power to the footswitch
wires. Applying power to the connector wires or
wiring the switch connector in any way other than shown
by this diagram can cause serious damage the QC-300 and void the product
