I just bought a used 600ex-rt and when I push the button on the flash head to rotate it, it makes a sort of beeping noise. I shoot wedding and I need that noise to stop. Can’t find the solution anywhere.

Electronic or physical? Regardless, I have four 600EX-RT flashes and none make any noise when pressing the head unlock button, other than a near-silent click of the release catch and the clicks of the detents with rotation or elevation.

Might want to contact the seller / return it if possible, or contact Canon for service.

Electronic. It’s weird. None of my other ones do this.
