Apple iPod touch iOS 5.1 - Manual (Page 45)

Setting a sleep timer
You can set iPod touch to stop playing music or videos after a period of time.
Set a sleep timer: From the Home screen choose Clock > Timer, then flick to set the number of
hours and minutes. Tap When Timer Ends and choose Sleep iPod, tap Set, then tap Start to start
the timer.
When the timer ends, iPod touch stops playing music or video, closes any other open app, and
then locks itself.
Converting videos for iPod touch
You can add videos other than those purchased from the iTunes Store to iPod touch, such as
videos you create in iMovie on a Mac, or videos you download from the Internet and then add to
iTunes. If you try to add a video from iTunes to iPod touch and a message says the video can’t play
on iPod touch, you can convert the video.
Convert a video to work with iPod touch: Select the video in your iTunes library and choose
Advanced > “Create iPod or iPhone Version.” Then add the converted video to iPod touch.
