UPC/EAN Security Level
The LS 400Xi 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.
UPC/EAN 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.
UPC/EAN SECURITY LEVEL 0
UPC/EAN Security Level 1
As bar code quality levels diminish, certain characters become prone to misdecodes before
others (i.e., 1, 2, 7, 8). If you are experiencing misdecodes of poorly printed bar codes, and
the mis-decodes are limited to these characters, select this security level.
