If the phone style has two black clips holding the small PCB in place over the mic assembly and it
does not have a tie-wrap as indicated in the picture below, one should be added. Install a small,
ordinary tie-wrap as shown below to properly retain the mic holder and element in place.
Re-install the base to the phone and secure with 4 screws.
