Bionaire BTF 4002 tower fan - Remove the annoying beep!

This is a piggyback to Jose Ruiz’ excellent video (am I allowed to share another’s video? 🤷🏻‍♀️ apologies if not) • Disable beeping sound ... on how to remove function beep the speaker from this fan. He demo’d the newer version in 2018(?) and this is an even older model with a different set up.
I’ve never done a video and I wing it fixing things as you can see as evidenced by my doing this in my sewing room - but I couldn’t find one on how to do this so here is a mediocre video that I hope you find helpful if your dog runs for the hills or wakes everyone at night with this most annoying and IMO useless beep.
