Wow, belay that last drivel from me!
My friend's cans are a slightly older model and he had a slider which polled for Bluetooth. We, working together via Zoom, decided that a button with a zig-zag on it (a biy like a heart monitor trace) was the Bluetooth button and it did indeed set the blue light flashing.
After I had far too hastily replied to your most sage advice, I realised that and pressed and help the power button.
It worked, a thousand thanks and a thousand pardons for not thinking your response through properly!
I must engage brain before composing replies!
Thanks again.
