They don’t make a click when you rotate the micro adjust arm when it’s engaged. This changes the distance by 1/2 yard increments. You can “feel” a click but it’s not audible. When you lock the “arm” into place there is a “click”. When the arm isn’t engaged the wheel is in neutral and can be turned. When it’s engaged the only way to turn the wheel is by rotating the arm. It’s not loud.
