Recommendation/Instructions

  1. It has been found that a short between the audio drain wire and microphone drain wire will cause this concern.
  2. Pull back the tape at X2 of the VCIM far enough to see where the bare wires are covered.
  3. Tape the bare wires individually to prevent them from shorting. Then tape the harness back up.
