The parameters of the bar code reader are grouped together in a parameter set and
permanently stored in memory. There is one parameter set in permanent memory and
one operating parameter set in volatile memory; in addition, there is a default parame-
ter set (factory parameter set) for initialization. This command can be used to edit the
first two parameter sets (in permanent and volatile memory). A check sum can be
used for reliable parameter transfer.
