To avoid truncation errors, the scanner can be programmed to only decode bar codes of one specific
length, i.e., containing a specific number of digits. It is also possible to program the scanner to only
decode bar codes of either of two specific lengths.
To set one or two lengths for all
symbologies:
1. Scan “START” to enter the
programming mode.
2. Scan “Enable length setting (H1)
for all symbologies”.
3. Scan a sample bar code of
the desired length.
4. Repeat Step #3, re-scanning
the sample bar code length or a
different bar code length to get 2
lengths.
5. Scan “END” to exit the
programming mode
To set one or two lengths for selected
symbologies:

3. Scan a sample bar code of
the desired length #1
4. Repeat Step #3, re-scanning
the sample bar code length or a
different bar code length to get 2
lengths.
5. Scan “END” to exit the
programming mode
“Setting the Number of Digits” can only be applied to Code 39, NW-7, 2 of 5, and MSI/Plessey. WPC,

2. Scan “Enable minimum length for selected codes” (HL)
3. Scan bar codes of the
required type and length .
4. Scan “END” to end the programming sequence.
