The CHECK DIGIT that appears after all parts of the MAC WORKING KEY have been entered is
similar to the checksum that is used to verify that the data programmed into a memory device such
as an EPROM is correct. The CHECK DIGIT can be verified by doing a RECEIPT PRINTER
TEST from the DIAGNOSTICS Menu and comparing the MAC WORKING KEY CHECK DIGIT
on the printout to the original receipt printout from the initial terminal setup. If the CHECK DIGIT
is different from the original, and the terminal is not operating correctly, the MAC WORKING
KEY is corrupt, and you should contact your service organization for assistance.

:
If the MAC WORKING KEY is not entered correctly, no message traffic can take place, so be sure
to enter the key accurately. If your second entry of the key does not match the first entry, you will
be warned and allowed to start over with the first entry.
