The notification is displayed during the test.
6.9.5 Device Errors Display
Error messages are displayed in the "Actual Status", "Summary Status" and "Device Test"

is Err, Wrn, OK, starting with the highest one. More detailed diagnostic information can be
displayed using the utility SW [42], [43]. An overview of the indicated Err messages is included in
