Bernafon Soundgate-TV adapter vs. Sennheiser SET840-S?

Okay, I sent an email to Bernafon U.S.A. and got a very rapid response saying that my Veras 9CPs do have an automatically-activated t-coil that will be activated by the field generated by a room loop or neck loop, if the field is strong enough. The tech guy also said that my audiologist can rig one of my four program switches to turn the t-coil on/off manually, if I want. I printed that email out and will take it with me to the audiologist in case she doesn’t know about that feature.
