• A digital playback device was developed for people with visual impairments so the buttons are large and tactile and it has a slot for the CD instead of a tray that the CD needs to fit into perfectly. • A digital playback device provides audio descriptions of the function of each button. All features of the player make it easier for clients to listen to any form of CD. • A digital playback device will either eject a CD or give you an audible error message if you insert the CD upside down. • You can play your standard music and book CD’s on a digital playback device but you cannot play the DAISY CD’s on a standard CD player.
