When a team member starts their shift, they need to remove the CommPack from the charging device and securely insert their personal issue Earpiece via the USB-C connector. Once the Earpiece is securely fitted in the individual's ear they can power on the CommPack, which will start the recording of a new session. Once the display illuminates with the Bodytrak logo and an ascending tone can be heard via the Earpiece, no further action is required by the wearer until the end of the session.
