5.5.1. Level 1
After switching on the smartCUE interface the LED DATA O.K. is blinking (with the Morse sign OK)
provided that the auto-diagnostics are in order. The internal microprocessor and basic internal circuits
are being tested. The tests for output line drivers are not included at this level.
