A conventional circuit requires a booster circuit for generating a voltage higher than an external power supply voltage, thus low power consumption is difficult to be achieved. A dispenser is mounted to one of the front, rear and opposing side walls and includes a detergent storage portion that is selectively exposed to release detergent into the washing chamber. A readwrite head assembly is disposed in relation to the storage medium. In addition, the system may adapt its processing based on location to take into account locally expected siren formats.
