In an arrangement allowing remote maintenance of a computer-controlled
system to be serviced, in particular a medical system, the maintenance
occurs via a spatially independent monitoring system in communication
with the system to be serviced. The system to be serviced is, among other
things, designed for the processing of access-protected data such as, for
example, patient data. Access to the access-protected data by the
monitoring ensues exclusively via an authorization unit associated with
the system to be serviced.
