Footswitch/handswitch wiring
The optional foot switch/handswitch is connected to the RJ-45 con-
nector on the left side of the QC-330.
The wiring of the switch is sometimes duplicated
by other external switching devices to facilitate re-
mote operation in conjunction with other devices
in a larger semi-automated system.
CAUTION
Never apply power to the footswitch or
handswitch wires. Applying power to the con-
nector wires or wiring the switch connector in any way
other than shown by this diagram can cause serious damage the QC-330 and void the
product warranty.
