The bistro! Key Operator is authorized to perform the
following service tasks of service level 1:
• Perform customer check-up
• Change descaling filter

The Key Operator also does repairs.
Service maintenance 1 and service maintenance 2 should
only be done by service personnel specially trained for
this machine.
To perform the tasks listed above the Key Operator has
access to the service routines, the component test as
well as to the counters “total number of brewings” and
“operating time”, to the “maintenance counters” (restricted
to customer check-up) and the “descaling filter” in the
machine data.
This access is protected by a special PIN (Key Operator).
The maintenance messages “customer check-up”, “service
maintenance 1”, “service maintenance 2” and “revision”
are displayed. They can be set with “KonfigTool”.
