I have set the alarm clock multiple times when I go to bed at night and it has failed to go off the next morning. The Repeat was set to Never and the Alarm Sound was set to the default-Light.It will tell me at the bottom of the screen that the alarm is set to go off for example: 7 hrs and 21 mins from now. I can test the alarm by setting it to go off in a few minutes and it always will work. Any suggestions?
