Sound in the jog

Hi everybody. I have discovered a strange sound when I move my jog wheel. May I be worried about that? You can see (and hear) it in the video. Thanks!

The video was just showing a still image for me.

Is it a physical mechanical sound from the mechanism of the jog wheel or a audio sound being made over the headphones or speakers or both ?

I’ve changed the video. Maybe you can see now… Anyway, it’s a physical sound. A little ‘clack’ that always sound in the same point. So I don’t feel that the jog brakes when it sounds.
