A method for use in a multifunction handheld device includes receiving a first plurality of digitally formatted files from a host device when coupled to the host device via a host interface. A selected one of the first plurality of digitally formatted files is played, the playing includes generating an audio output. The method monitors for a low voltage condition produced by a low battery voltage. When the low voltage condition is detected, a first fail safe algorithm is enabled to disable the audio output, store an audio setting corresponding to the playing of the audio output, and to shutdown the multifunction handheld device.
