No Read
With No Read turned On, the scanner notifies you if a code cannot be read. If using 
an Scanning Tool Scan Data Window, an “NR” appears when a code cannot be read. 
If No Read is turned Off, the “NR” will not appear. Default = Off.
If you want a different notation than “NR,” for example, “Error,” or “Bad Code,” you 
can edit the output message with NRDSTR menu command, such as: NRDSTRError 
or NRDSTRBad Code.
Video Reverse
Video Reverse is used to allow the scanner to read barcodes that are inverted. The 
Video Reverse Off barcode below is an example of this type of barcode. Scan 
Video Reverse Only to read only inverted barcodes. Scan Video Reverse and 
Standard Barcodes to read both types of codes. 
Note: After scanning Video Reverse Only, menu barcodes cannot be read. You must scan 
Video Reverse Off or Video Reverse and Standard Barcodes in order to read menu 
barcodes.
Note: Images downloaded from the unit are not reversed. This is a setting for decoding only.
