Set Current Parameters to Default Values
TheRealScan74comesfromthefactorywithspecificdefaultvaluesalready
determinedforthevariousprogrammingparameters.Sometimesotherdefaultvalues
aredesired.Thisfunctionpermitsthecurrentparametersettingstobestoredassoft
defaultvalues.Whenthisisdone,scanningtheDefaulttagsetstheparametersto
these
valuesratherthanthefactorydefinedvalues.
