When Check Character is set to Validate and Transmit, the scanner only
reads Code 39 bar codes printed with a check character, and will transmit
this character at the end of the scanned data. Default = No Check Charac-
ter.
Code 39 Redundancy
If you are encountering errors when reading Code 39 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 Code
39 Redundancy 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.
Code 39 Message Length
Scan the bar codes below to change the message length. Refer to
Message Length Description (page 6-2) for additional information. Mini-
mum and Maximum lengths = 1-80. Minimum Default = 3, Maximum
Default = 80.
