The BCHM is provided with a 3.5mm locking connector for connecting the microphone to the BCWBT transmitter. Plug in the microphone's connector and secure the connection by turning the metal slip ring clockwise to thread it on the jack. To unplug, reverse the process. Wear headset so that it wraps around the back of the head. The curved earpieces will fit over the ears. While wearing the headset, adjust the Boom Arm so that the microphone is about two inches from your mouth. Do not place the microphone too close to the mouth.
