Multiple SymbolsWhen this programming selection is turned On, it allows you to read multiplesymbols with a single pull of the scanner’s trigger. If you press and hold thetrigger, aiming the scanner at a series of symbols, it reads unique symbols once,beeping (if turned on) for each read. The scanner attempts to find and decodenew symbols as long as the trigger is pulled. When this programming selectionis turned Off, the scanner will only read the symbol closest to the aiming beam.Multiple Symbols OnNo Read* Multiple Symbols OffWith No Read turned On, the scanner sends an “NR” to the host if you pull andrelease the trigger without reading a code (e.g., bad bar code). If No Read isturned Off, the “NR” will not be sent to the host.No Read On* No Read OffIf you want a different notation than “NR,” for example, “Error,” or “Bad Code,”you can edit the output message using the Data Formatter (page 5-5). The hexcode for the No Read symbol is 9C.Video ReverseVideo Reverse is used to allow the scanner to read bar codes that are inverted.The “Off” bar code below is an example of this type of bar code.Note: If additional menuing is required, Video Reverse must be disabled to readthe menu bar codes and then re-enabled after menuing is completed.Video Reverse On* Video Reverse Off3 - 12 2020/3820 User’s Guide
