Appendix E Decode Zone 

 
 
The decode zones for the Cordless Hand Scanner is shown below.  The 
minimum element width (“X Dimension” or bar code “size”) is the width in 
thousandths of an inch (mils) of the narrowest element (bar or space) in the 
symbol.  The figures shown are the typical scanning distances (depths of 
field) for selected bar code sizes.  The maximum usable length of a bar code 
symbol (Width of Field) at any given range is also shown.
