a car battery through the cigarette lighter socket.
An AC adaptor (AD-5, optional) is required when using household current. Use
only a genuine CASIO adaptor with the same voltage rating (100,117,220, or 240)
as the power supply in your area to prevent component damage. Plug the AC
adaptor into the AC outlet and the cord into the unit. This will automatically
cut off the battery power supply.
