Security
Level
The scanner offers four levels of decode security for delta bar codes, which include the Code 128 family, UPC/EAN, and Code 93.
Select
increasing
levels
of
security
for
decreasing
levels
of
bar
code
quality.
There
is
an
inverse
relationship
between
security
and
scanner
aggressiveness,
so
choose
only
that
level
of
security
necessary
for
any
given
application.

Security Level 0: This default setting allows the scanner to operate in its most aggressive state, while providing sufficient
security
in
decoding
most
“
in-spec
”
bar
codes.
Security Level 1: Select this option if misdecodes occur. This security level should eliminate most misdecodes.
Security Level 2: Select this option if Security level 1 fails to eliminate misdecodes.
Security Level 3 : If Security Level 2 was selected and misdecodes still occur, select this security level. Be advised,
selecting
this
option
is
an
extreme
measure
against
mis-decoding
severely
out
of
spec
bar
codes.
Selecting
this
level
of
security
significantly
impairs
the
decoding
ability
of
the
scanner.
If
this
level
of
security
is
necessary,
try
to
improve
the
quality
of
the
bar
codes.
