Q: The battery on my ULTIMATE EARS BOOM ran out overnight and my back up alarm didn’t go off on my iPhone (or iPad). Why?

A: Your ULTIMATE EARS BOOM always sets a backup alarm on both the speaker itself and on your source device, just in case something goes wrong. For Apple devices, ensure that your device’s Ringer and Alert settings are enabled by sliding theChange with Buttons setting to ON. To find this setting, go to: 

For iOS 5.1.1
Settings >> General >> Sounds >> Ringer and Alerts

For iOS 6.x and 7.x
Settings >> Sounds >> Ringer and Alerts
