Enables/disables calculation and verification of optional MSI/Plessey
check characters.
To set this feature:
1. Scan the SWITCH bar code.
2. Scan either the enable or disable bar code below. You’ll need to
cover any unused bar codes on this and the facing page to ensure
that the scanner reads only the bar code you intend to scan.
3. Complete the programming sequence by scanning the SWITCH
bar code.
MSI/PLESSEY CHECK CHARACTER CALCULATION = DISABLE
MSI/PLESSEY CHECK CHARACTER CALCULATION = ENABLE
NOTE
If check character calculation is disabled, the risk is increased that a mis-
read can occur. When disabled, any check characters in a bar code are
treated as data characters.
