Abstract
Abstract The present invention is directed to an X-ray diagnostics installation having control elements for control of specific components of the installation. In order to prevent inadvertent actuation of the elements, an activation switch must be actuated to cause each of the control elements to be effective for a predetermined time. The length of the predetermined time can be increased by actuation of one of the control elements following the actuation of the activation switch.
