how can i fix my sony cdx-505rf 10 disc multichanger?

Hi Kelly,

When the battery goes flat you need to push the RESET button.
Simple enough except that you need to find it! It is on the side of the little box that will be hidden away somewhere between the changer unit and the stereo. Follow the leads from the changer, the radio itself or the display panel and you will find it.
Good luck,
James.
