Sounds like a great house and that it works well for short range RF connections.
Do you pair the TV Connector to your hearing aids? The reason I ask is that is typically part of configuring a Bluetooth system.
I just looked at the technical data sheet and the manual for an Oticon TV Adapter 3. No mention of Bluetooth but it does state that it uses the 2.4 GHz (ISM band). I also pair the aids with the adapter. Dredging around the FCC database I found the application for the Oticon adapter - sure enough it does use Bluetooth. The listed power output for Bluetooth is 4 mW and there is another power level of 21 mW for another mode in the same frequency band that is not marked as Bluetooth.
The manual for the TV adapter claims a range of up to 50 feet with a maximum emission of 17.1 dBm EIRP. I have no idea how to convert dBm (dB-milliwatts) to transmit power as I haven’t a clue as to antenna gain. In my case, I can walk away from our living room TV (adapter under it) through the dining area and kitchen into the garage and still hold a good connection to the adapter (about 45 feet).
The same FCC site also has the doc for the ConnectClip - it lists two Bluetooth power levels (1 and 5 mW) and two other modes of 8 and 12 mW that are not marked as Bluetooth.
The technical data sheet for the ConnectClip lists two wireless range figures:
up to 33 feet with Bluetooth Class 2 devices (e.g. mobile phones)
up to 65 feet between ConnectClip and hearing instruments
I have no idea what the modes not marked as Bluetooth are but they are in the same band as Bluetooth and other 2.4 GHz unlicensed devices.
The FCC site also lists a number of Oticon hearing aids - most show Bluetooth with 1 mW or less for power output.
