Message Length
The message length selection is used to set the valid reading length of the bar
code. You may wish to set the same value for minimum and maximum length
to force the scanner to read fixed length bar code data. This helps reduce the
chances of a misread.
EXAMPLE:
Decode only those bar codes with a count of 9–20 characters.
Min. length = 09 Max. length = 20
EXAMPLE:
Decode only those bar codes with a count of 15 characters.
Min. length = 15 Max. length = 15
For a value other than the minimum and maximum message length defaults,
scan the bar codes below and then scan the 2–digit value and Save bar codes
on the Programming Chart inside back cover. Minimum and Maximum
Lengths = 0–48.
If you make an error while scanning the digits (before scanning Save),
scan Discard on the back cover, scan the Minimum or Maximum bar
code, scan the correct digits, and Save again.
Maximum (Default =48)
