I just bought a modular helmet and a SMH10 to go along with it. I was hoping to have my new helmet paired up to the Freewire on my F6b in addition to having it paired up to my open face helmet. What I just discovered is that Freewire will only pair to one SMH10, so I have to umpair it from the open face helmet before it will pair with the new modular helmet. But I can't seem to find anywhere that explains how to unpair my first SMH10 from the Freewire. I could probably do a factory reset, but that seems to be a last resort. Is there another way to unpair it from my first SMH10?
