You must first load the magazine with discs before you can play a compact disc. Each of the 12 trays holds one disc. Slide the button on the top of the magazine and gently pull out one of the trays. Load the trays from top to bottom, placing a disc on the tray label side up. If you load a disc with the label side down, the disc will not play and an error will occur. Gently push the tray back into the magazine slot until it locks into place. Repeat this procedure for loading up to 12 discs in the magazine. Once you have loaded the discs in the magazine, slide open the door of the compact disc (CD) changer. Push the magazine into the changer in the direction of the arrow marked on top of the magazine. 3-36
