The appliance includes security and control logic, a communication interface coupled to the distribution network, and circuitry or software for disabling operation of the appliance. The controller transmits individualized information to the appliance via the distribution network independently of a physical location of the appliance. The controller may be a personal computer or a portable unit. The appliance includes a unique identification code stored therein, and the individualized information contains an address portion containing this unique identification code. The appliance also includes a security code stored therein. The security code must be transmitted to allow operation of the appliance.
