Please push the power supply button after pushing the home button when you erase the screen after the alarm is set. The alarm sound can be set according to an arbitrary number of seconds for an arbitrary iPod library tune. ( The correspondence music file is only AAC(.m4a) and MP3 of 44.1k and stereo file.
