Using AC power
An AC adaptor (AD-5, optional) is required when using household current. Use only
genuine CASIO adaptor with the same voltage rating (100, 120, 220, 230 or 240V) as
the power supply in your area to prevent damage to internal components. Be sure to
turn the power of the unit off before you connect the adaptor to the unit. Plug the AC
adaptor into the AC outlet and the cord into the unit. This will automatically cut off
the battery power supply.
