Mounting the connector
Mount the connector into a cutout, as shown in Figure 12 below.
Connect the eight wires as follows:
• Two for the microphone
• Two for audio
• One for power
• One for ground
• Two for audio shields
Audio and microphone wires should be connected to the back of the
existing microphone and headphone jacks, leaving existing jacks
intact for use with conventional headsets. This is usually the fastest
installation method (see Figures 1 – 4 for reference). Audio shields
should be connected to ground at the existing jack.
(Caution: Use of two headsets wired in parallel is not advised. This
may result in reduced performance.)
