the machines on the network. Wait until an operator has
finished.

report.
PLU FILE ERROR This message appears after switching on the machine or
after amending the PLU file should it detect any corrupt
PLUs.
At a stand–alone machine, replace the file using the
DCU or re–create all the entries at the keyboard.
If this message appears at the master, swap the
machine with a slave set to sub department 0. Amend the
network map. Re–assign keys if necessary.
If this message appears at a slave, copy the PLU file to
the slave (see Part 3 of the Users’ Handbooks).

format entered at machine YY. Re–programme the PLU or
machine with the correct format.

entered the correct unit price. If you are in receipt mode,
print the receipt for any current transactions.
