5-30
Note: The UPCE0 and UPCE1 parameters are always set to match each
other. Therefore if a change is made to a parameter to either the
EPCE0 or UPCE1 Advanced Properties that same change is
automatically made to the Advanced Properties for the other
symbology.
Note: UPCE0 and UPCE1 are enabled as the same symbology at the
scanner. Therefore, the only way for UPCE1 configuration to be used
is if UPCE0 is disabled. When UPCE0 is disabled, it is scanned by the
imager but rejected by Data Collection Wedge.
