A:AnswerTo set the Sleep timer, go the the "home" screen. (See Pic #1) Scroll all the way to the left and select the "Settings" icon. NEXT scroll to the right to the Sleep timer selection and select it. ( See Pic #2) The timer will advance in 30 minute increments up to 4 hours I believe, before returning to the "OFF" setting.
I hope this helps.
