UPC/EAN Security Level
The scanner offers 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.
