Observe the ESD precautions. --> See "Important Information" on page 28 – 523!
Remove the SIK from the defective MC 422 and insert it into the new MC 422.
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 number is displayed on the screen 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.
Remove the label with the SIK number (over the ID plate) from the MC and apply it on the new
MC 422 (over the ID plate).
