How do I remove all songs and return my RCA h100a mp3 player to it factory settings

You will have to do that using a computer, to do that using a computer, you will have to connect the device to a computer using the usb. Then when the autoplay is on, select open file to view folder, then you go to the music on the device, then you highlight all and right click, then you select delete, it will delete all the songs off the mp3 player and from there it will be the way it was when you first bought it, empty and ready to receive new music on it.
Hope this was helpful. Thanks for using fixya.
