NEC 2 of 5 Redundancy
If you are encountering errors when reading NEC 2 of 5 bar codes, you may want to adjust the redundancy count. Redun-
dancy 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 NEC 2 of 5 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.
