Holding down the volume button will cycle up and down through the volume settings. Yet I suspect that the internal speaker has finally given up the ghost. This is a pretty old Whistler RD. I would highly recommend upgrading to a modern radar detector which has much better overall performance. One of my favorite current Whistler products for the budget conscious is their Pro78. This model provides very good performance at a reasonable price.
