8. Position the oval-shaped foam piece around the perimeter of the PROIWT microphone as
depicted below.
9. Position the PROIWT interface assembly onto the speech body channel as depicted below. Verify
that the rubber skirt of the mask has not been forced out of the speech channel body groove.
Secure the interface into position using the four Torx screws from step 1. Hand-tighten the screws
evenly and DO NOT OVER-TIGHTEN.
10. Don the facemask and determine which microphone cable is best suited for the user. The
microphone cable will connect the interface assembly to the speaker and is supplied as a 12” or
18” length. The selected length shall not restrict head movement of the user and should be
positioned to minimize the potential for snagging. The cable contains locking connectors on both
ends. To engage the cable simply line up the contactors and press together. To disconnect the
cable, pull back on the outer shell to release.
