If you'd like to change the item prices on the Uniwell NX-5400, turn the MA key to Z1 and depending on if it's a scanned item or on the register itself, do the following.
SCANNER: Press "305" then press "X" register should now display (P--305), now scan the item. You'll now see the current item price. Enter the new price and press "X" "CL" "CL". You're price should be changed and ready to use.
ON REGISTER: Press "305" then "X" now check the number of the item you'd like to change on the register and enter it followed by "." You'll see the old price on the screen, insert the new price and press "X" "CL" "CL" The price should now be changed.
Hope this helps. Let me know if you need any further assistance.
