parameter options, you have to re-enter the Specific Programming Mode by scanning the two Hex tags again.

The following figure shows how to proceed through a Specific Programming Mode where you change only one of the parameters. This figure presents the specific programming mode for Bar Codes 2 program parameters. Notice that once you have entered the Specific Programming Mode, if you scan the Hex A, Hex B, Hex C, Hex D, Hex E, or Hex F tag, you can enter the specific parameters that correspond to that tag. After you record the parameters, the scanner immediately returns to the Base Programming State. To return to programming, you scan the Hex 1 and Hex 4 tags again and re-enter the Specific Programming Mode. From this point, you can enter either all parameters or another specific parameter.
