Directly following the Progress Bar is the Sleep Timer button. Invoking the Sleep Timer will stop playback after a set period of time or at the next chapter boundary.
Activating the Sleep Timer button once will set the Sleep Timer for 15 minutes, twice will set it for 30 minutes, three times will set it for 45 minutes, four times will set it for 60 minutes, and five times will set the Sleep Timer to stop playback at the end of the current chapter. Activating it a sixth time will turn the Sleep Timer off. At the conclusion of the selected period the volume will fade for10 seconds and playback will stop. Activating the Play/Stop button will cancel the Sleep Timer.
Each time the button is activated BARD Mobile will announce the amount of time the Sleep Timer has been set for or, if it has been activated for the sixth time, it will announce that it has been turned off.
