I'm repairing a Marconi 2019 Signal Generator and I want to re-calibrate the thing. For this I need the code to overcome the "second degree protection" (top-secret ;) in this apparatus. Does anyone know this key-sequence?
Marconi 2019 second degree protection code?

Quoting from the technical manual:
"Press SECOND FUNCT, 0, then in the rotation given first MOD OSC then ON/OFF and finally CARRIER FREQ keys holding down all three keys for a minimum of 5 seconds. Follow this by pressing SECOND FUNCT and the numeral 7, 8, 9 or '.' as required."
