I'm am just now switching from series 2 units to the premiere. With my series 2 units, when you FF and/or rewind, you hear "doot" sounds with each press of the button. For three presses, "doot, doot, doot". With premiere, all the buttons have their respective sounds, but when using the FF and/or rewind, there is no sound at all - no "doot, doot, doot". Is it supposed to be like that, or is there someway I'm missing to turn this feature "on"?
