Normally the NC software or the MC are only exchanged by or upon consultation with the

Caution
The SIK (System Identification Key) will remain with the machine.
It must be inserted into the new or replacement MC; i.e. all enabled options are still
available.
Only defective SIKs are exchanged.
If options were enabled on the defective SIK, you will receive the code numbers to enable
these on your new SIK after giving us the number of your defective SIK.
The SIK number is displayed after entering the code "SIK". It can also be found on the SIK
housing or on a sticker below the ID label of the MC.
The defective SIK has to be returned.
Caution
Since the iTNC consists of two components (MC 422 und CC 422) you can exchange each
component individually or both together.
When sending us both components, do not forget to state both ID numbers.
The ID number of the MC can be found on the right side of the housing.
The ID number of the CC can be found on the underside of the base plate of the housing.
