You may also purchase a “Universal” type AC adapter that allows you to select the desired output voltage, and normally includes several of the most popular plug sizes. Make sure that the adapter you purchase is “UL Listed”. Look for the “UL” mark on the packaging and on the adapter itself.

Connect the adapter housing directly to a 120V AC outlet. Connect the appropriate adapter plug to the “DC Input 4.5V” jack on the side of the CD player. Remove the rubber cap from the Input jack before connecting the adapter plug. Replace the rubber cap when the adapter plug is removed from the player.
