Ok. You will have to allocate the dept function to them then.
Try this:
Turn key to PGM mode
9950
. (decimal point)
a/FOR (next to decimal point)
1
Now type the dept number on the numeric keys e.g 12
Now press the new dept button that you want to place the dept on.
CA/AT (cash button)
If you get an error, then it will need to be done in service mode, but try that for a start.
If it programs the new depts and prints them out as you program but they won't work in REg mode, then that is okay. They may need a status assignment which we can do next. See how you get on.
