Linear Security Level
This parameter allows you to select the security level appropriate for your bar code quality.
There are four levels of decode security for linear code types (e.g., Code 39, Interleaved 2 of
5). Higher security levels should be selected for decreasing levels of bar code quality. As se-
curity levels increase, the scanner’s decode speed decreases.
Double-tapping on this parameter displays a dialog box in which you can enter a value from
1 to 4.
Linear security level 1 specifies that the following code types must be successfully read
twice before being decoded:
Linear security level 2 specifies that all types of codes must be successfully read twice
before being decoded.
Linear security level 3 specifies that code types other than the following must be success-
fully read twice before being decoded. The following codes must be read three times:
Linear security level 4 requires that all code types be successfully read three times before
being decoded.
Important: Psion Teklogix strongly recommends that this parameter only be enabled by
personnel with a very strong understanding the scanner and how it operates.
Scanning the wrong parameter code can result in an inoperable unit; if this
occurs, the unit will need to be shipped to a depot for repair.
