I have prodded in this forum and other places on the web, but could not find assistance. I want to set up the SP3 alarm clock, and have it ring to wake me up in the morning. I have tried with the unit plugged into AC, and on battery power. In both cases, it seems the SP3 is shutting down. I get no alarm clock or even emails received during the night. What do i need to do in order to have it running in some mode so it stays awake during the night?
