 SCP-624 is a SanDisk Sansa E200-R MP3 player and voice recorder. Although the original owner's manual claims there are preloaded sample songs, there are no files stored within its memory when played on normal speakers. Uploading music to SCP-624 seems to be impossible, as every program tested, including iTunes, Rhapsody, and Yahoo Music have all returned with encoding errors. When powering up SCP-624 through headphones, a tone will play, and this tone will be picked up through SCP-624's microphone. If SCP-624 does not detect the tone, it will shut down as if it were locked. If SCP-624 hears the tone from normal speakers, SCP-624 will power on normally, but contain no stored data.
