When you get in range of your TV connector and you hear the two tone (ding-dong) chime in your Phonak HA, you can short press either button on one of your aids to connect to the TV connector , without taking the phone and switching in the myPhonak app.
But you need to innitiate the short button press within a certain timeframe (15 sec.) after the double chime signal.
After this timeframe you need the MyPhonak App to switch to the TV stream
If you miss the short time to connect (seems more like 10 seconds max to me), you can use long presses to scroll through to connect. No need to open the app.
On another note, I have my TV Connector on a “smart plug” so I can fully disable it. I also have Roger devices on Manual plus beep, for similar reasons.
