UPC-E0 On/Off
Most U.P.C. bar codes lead with the 0 number system.  To read these codes, use the UPC-E0 On selection.  If you need to 
read codes that lead with the 1 number system, use UPC-E1 (page 7-24).  Default = On.
UPC-E0 Expand
UPC-E Expand expands the UPC-E code to the 12 digit, UPC-A format.  Default = Off.
UPC-E0 Addenda Required
When Required is scanned, the scanner will only read UPC-E bar codes that have addenda.  Default = Not Required.
