Yep it's beeps or clicks. Mine didn't do it earlier today but now it is. I don't know if it is hardware. I went back to the store and they pulled out 5 of them and they all clicked or beeped. I was hard to hear so we went into the back and I showed the store manager. She shrugged her shoulders.
F-ing thing sucks and Motorola covered it up so as not to take a cost or reputation hit.
