To enter a digit 0-9, simply press the key that has the desired digit, and a ‘*’ will appear. To enter
a Hex character (A through F), first press and hold down the <BLUE> key. While holding down
the <BLUE> key, press the numbered key (1-6) that corresponds to the character you want to enter,
as listed in the table on-screen (1=A, 2=B, 3=C, 4=D, 5=E, 6=F). A ‘*’ character will appear.
Release the <BLUE> key. Repeat for each character in the key. Press the <CHANGE> key to clear
the entry and start over. Press the <LEFT ARROW> key to back up and erase a character.
You must enter the key sequence TWICE for each KEY BLOCK: after the second entry, you will
be prompted to enter a second key part. In most instances you will answer NO to this prompt, but
in some cases a second sequence of characters may need to be entered (this requirement is processor-
specific).
The CHECK DIGIT that appears after all parts of the MAC MASTER 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 MASTER 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 MASTER KEY
is corrupt and you should contact your service organization for assistance.

:
If the MAC MASTER KEY is not entered correctly, no message traffic can take place, so be sure
to enter both KEY BLOCKS 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.
