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 de-
creasing 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 appli-
cation.
• 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 elimi-
nate 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.
