An apparatus for supporting an operator in operating a medical device has a signaling device that signals a necessary operation of a component to be operated of the medical device. The signaling device emits a signal from the component to be operated and/or orients a signal onto the component to be operated. The signaling device emits at least one of an optical, an acoustical, and a haptical signal. The apparatus also includes a control apparatus that controls the signaling device based on the component operation to be performed, with the control by the control apparatus being independent of an operator request.
