To wipe the memory and to program for card processing, I need two passwords for this machine. One password is correct - 1, alpha, alpha, 6, 6, 8, 3, 1. But the second password that should be the same as above (it is called "file group password") was changed for some reasons. And this password is unknown. I tried everything that I found in Internet, including 0000 or 1234 or 9999 or 1111, etc. Is it possible to resolve this problem or I have to thru away this CCM?
