Operator input sequence steps - NCK general reset
1. Turn the NCK startup switch (SIM/NCK label) on the NCU to position "1".
2. Execute POWER ON or Hardware RESET.
3. NCK general reset is requested.
4. After an error-free boot, the system generates the number "6" and a flashing point on the
status display of the NCU.
5. Turn the NCK startup switch back to the "0" position.
