The RE3-ACC-PCA is an accessory kit allowing the RE3 bodypack transmitter to be mounted into the Electro-Voice Polar Choice PC Boundary Sat and PC Satellite models, while also allowing the transmitter to be used in other traditional bodypack transmitter applications.

The adapter accessory mounts permanently to the RE3-BPT via its strong adhesive backing, and the supplied belt clip allows the RE3-BPT with the adhesive mount attached to be securely-clipped to a belt, waistband, or other garment.
