If the symbol isnine or fewer alphanumeric characters with a data identifier of S, it is a “serialnumber” symbol.Chapter 8, Using a Quick Check 800 Verifier lists the symbol types and errormessages. If an application does not have a unique symbol format, the unit willsimply display the symbology.♦ To review the format procedures:1. Scan a symbol.2.
