upc 12 price variable barcode programming for TE-3000

I am trying to figure out how to program the TE-3000s to be able to scan price variable upc codes (12 digit) printed from a Hobart Quantum scale.

I have the dealers manual but it only shows how to program the TE-3000s to be able to accept such codes, but it does not specify how you program each different item.

Example, the Flags 1 & 2 are 2 and 1

UPC barcode 21212145502589

The item code is 212145 and 258 is the price.

another same item with different price could be 212145202885 whether the item code is 212145
and price is 288

Any ideas?

For the life of me, I cannot seem to figure what is the One Touch NLU and OBR are used for. Does these keys have anything to do with programming of weight or price variable codes?

Thanks for all responses.
