UPC/EAN Security Level

The scanner offset four levels of decode security for UPC/EAN bar codes. Increasing
levels of security are provided for decreasing levels of bar code quality. There is an
inverse relationship between security and scanner aggressiveness, so be sure to choose
only that level of security necessary for any given application.
Security Level 0 - This is the default setting which allows the scanner to operate in its
most aggressive state, while providing sufficient security in decoding in spec UPC/
EAN bar codes.
Security Level 1 - As bar code quality levels diminish, certain characters become prone
to mis-decodes before others (i.e., 1, 2, 7, 8). If you are experiencing mis-decodes of
poorly printed bar codes, and the mis-decodes are limited to these characters, select
this security level.
Security Level 2 - If you are experiencing mis-decodes on poorly printed bar codes, and
the mis-decodes are not limited to characters 1, 2, 7 and 8, select this security level.
