4. Troubleshooting Help Functions
After startup, CORINA performs an internal self-test. The test results are filed in FIFO
memory. If an error is detected, an alarm signal also sounds three times in succession. In
the models 5 + 6 (CORINA standalone) a sound repeated three times does not indicate an
error, but the switching on of the operating voltage.
Meaning of the error messages:
