ABSTRACT:
A compact disc player is modified to convert it into a program repeater that plays preselected messages on a repetitive basis. Unused or used information channels in the CD player are employed. A sequence controller which is added to the conventional circuitry controls the operation of the conventional controller. When power is supplied to the CD player, a power monitor activates the sequence controller and the sequence controller then sends control signals to the controller, instructing it to activate the CD player and to place the CD player in its PLAY, AUTO REPEAT, or other preselected modes. The sequence controller also looks for a proprietary code placed on an unused information channel, and sends a deactivation signal to the sequence controller if the code is not found. An internal or external timer may be employed to provide power to the CD player at predetermined times so that the CD player operates as a program repeater entirely without human intervention.
