MX-4000W 5. Operator Function
5.9.2.1.4.2 MASTERK3 IMPORTING ERROR
If your importing 2 PIN MASTER KEYS is wrong, you will see the screen as depicted as below.
5.9.2.1.4.3 EDIT MACK3.
Editing MAC MASTER KEYS is same to editing PIN MASTER KEYS. But if user choose 'TDES' by
'KEY MODE' button, there is no need to import MAC MASTER KEYS. So the screen as depicted as
below is only shown when a owner of ATM choose 'TDES, TMAC(11)' mode.
