I just discovered a great Easter Egg in the RC Pro. If you want to silence the beep, just turn the volume all the way down(Fn + right scroll wheel up). That triggers another dialogue to disable beeping.  Easy.

That's an amazing find, I will give it a try.

Brilliant.  Thanks for sharing.

Here is a screenshot

Huh!?! Great find and better yet thank you for sharing!

You can also disable the sound at „every“ boot

Good information on this

This does NOT work for the pairing beeping sound. So I’m in a house with relatives and I have to go and hide to pair my drone. It’s infuriating. Like almost to point of wanting to smash it.

... pairing is a quite other thing!   

Why do you need to pair your drone after the first time? If you are talking about the startup sound, start it outside when you go fly.

I just purchased the RC Pro, i don't see a button labeled "Fn" on it. Are you actually referring to the standard RC-N1 controller?  
I would like to mute the button beeping sounds if possible.

Nice find! Will come in handy when doing night flights in the wilderness trying not to scare the wildlife…

It's technically the "Back" button, upper left button on the RC Pro. See page 18 of the current manual for a list of the combinations.

Exactly this. How do we get it to be quiet when turning the RC pro on and the drone as well. I just want silence. Even outside.

Thanks for this.
