ROTOR MAX
---
The rotor has been changed. The
maximum speed of the installed rotor is
higher than that of the rotor that was
previously used and this has not yet been
detected by rotor recognition.
Set a speed up to the maximum
speed of the rotor that was
previously used. Press the
START / IMPULS
key to run rotor
recognition. See chapter, "Rotor
Recognition".
