How do I change a PLU price on a Uniwell NX-5400F?

The instructions I received from my tech (who is now not available) is:
1) Set key position to 'Z1/P'
2) Enter PLU code
3) Press 'PRICE' button
4) Enter price (without decimal)
5) Press the 'X' button
6) Press the 'CL' (clear) button
End of instructions, but this is not working. What's being missed?
