Any tips to disable bluetooth on a generic treadmill?

Hi,

I have a cheap generic treadmill that the family uses for excercise. It has a crappy bluetooth speaker built into it. This is a feature that i neither wanted nor have ever used.

Unfortunately the bluetooth has recently become faulty, and whenever the machine is turned on it seems to send out pulses that disrupt all the bluetooth devices nearby (including the mouse and keyboard for my pc).

I’ve opened up the machine, and as far as i can see everything (display, buttons, controllers etc) all seem to be together on one board. Just wondering if anyone has any ideas for identifying and disabling the bluetooth components, or whether there is likely to be some form of antenna that i could disable to mitigate the interference.

Many thanks
