Caution
Observe the ESD precautions. --> See "Important Information" on page 28 – 523!
Remove the SIK from the defective HDR and insert it into the new HDR.
Caution
The SIK (System Identification Key) will remain with the machine.
It must be inserted into the new or replacement HDR; 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 on the screen after entering the SIK code. It can also be found
on the SIK housing.
The defective SIK has to be returned.
The original SIK must be inserted into the new HDR.
Loosen the shipping brace; the HDR must oscillate freely! --> See sticker on the HDR.
Caution
Do not overexpand the locking hook but just lift it slightly.
Insert and lock new HDR (also press the handle down).
