The PROIWT interface will install into the PRO PP facemask in place the facemask voice emitter front
cover. The speaker portion of the system will clip to the lapel of the user’s shirt or to the harness of the
BioPak 240R respirator. A cable is utilized to connect the facemask interface components to the speaker.
The speaker is provided with a coiled cable attached that will interface with the 2-way radio supplied with
the Innovative Wireless Technologies communication system.
Warning:
Do not damage the voice emitter cup of the facemask during PROIWT installation.
The voice emitter, located internal to the mask, cannot be cut, slit, punctured, or
otherwise damaged. A damaged voice emitter will result in a breach of the respirable
air circuit of the BioPak.
1. Using a T20 Torx screwdriver, remove the four front cover screws and reserve for reuse as
depicted below.
2. Inspect the rubber skirt of the mask and verify that it is properly positioned within the groove of the
speech channel body as depicted below. The skirt must be positioned in the groove of the speech
