An X-ray system, comprises a motor-adjustable C-arm, an input device which has a first actuating device and is mechanically connected to the C-arm, a dead man's switch, which is mechanically connected to the C-arm, and a pattern recognition module which cooperates with the input device and the dead man's switch, and is provided to determine a classification of actuating signal patterns generated via the first actuating device. A first signal group is activatable when the dead man's switch is actuated, and a second signal group is activatable when the dead man's switch is not actuated.
