ABSTRACT:
An electrical device (1), especially a CD changer, is proposed, which offers protection against theft. An electrical device (1) is connected by a connecting cable (35) to a second electrical device (5), especially to a car radio. The connection has a first pole (95) for a first reference potential (15) and a second pole (100) for a second reference potential (25). In the second electrical device (5), the first reference potential (15) is connected to the second reference potential (25). A third pole (55) contains a supply voltage feed for the first electrical device (1). In the first electrical device (1), a control unit (40) is provided for controlling the first electrical device (1). When the connection between the first and second poles (95, 100) is cut, the residual charge remaining in the first electrical device (1) produces a voltage difference between these two poles (95, 100), as a result of which a security procedure is initiated in control unit (40).
