MSI Redundancy
If you are encountering errors when reading MSI bar codes, you may
want to adjust the redundancy count. Redundancy adjusts the number of
times a bar code is decoded before transmission, which may reduce the
number of errors. Note that the higher the redundancy count, the longer it
will take to decode the bar code. To adjust the redundancy, scan the MSI
Redun-dancy bar code below, then scan a redundancy count between 0
and 10 on the Programming Chart inside the back cover of this manual.
Then scan the Save bar code. Default = 0.
