To avoid truncation errors, the scanner can be programmed to only decode bar codes of one specific length,

of either of two specific lengths.
To fix one (1) length (or number of digits) of bar code:
1. Scan "START" to enter the programming mode.
2. Scan "Enable fixation" bar code.
3. Scan a sample bar code of the desired length.
4. Repeat Step #3, re-scanning the sample bar
code.
5. Scan "STOP" to exit the programming mode.
