Recently one of my Lametrics (out of 4 I have in the office) started playing music randomly. After about 5 seconds it stopped and scrolled a message, something along the lines of "account signed out from another device" I'm not 100% sure on that.
I have NEVER used any of the Lametrics as a BT speaker, nor the radio function. I anticipate some neighbor found the bluethooth broadcast of "LM####" and connected to it.
How can I disable bluetooth/radio entirely?
