Caution:
Bias voltage supplied to the microphone must come from voltage and resis-
tance ranges specified above. Voltages supplied in excess of those stated
in the specifications can cause microphone failure and void warranty. The
mic audio signal is present between the ring and barrel of the mic plug; tip is
reserved for transmit keyline.
Inside each ear cup of your headset you will notice an oval fabric piece. This
is intended to prevent debris from entering the speaker element and to help
prevent feedback of the ANR system. Do not operate the ANR modules
without these fabric pieces in place.
