Configuring Your Scanner
23
UPC/EAN Security Level
The scanner offers three levels of decode security for UPC/EAN barcodes:
Level 0: If you are experiencing misread of poorly-printed or out-of-spec. barcodes, especially in characters 1, 2, 7, and 8 in level 1, please select level 0. Selection of this
security level may significantly impair the decoding ability of the scanner.
Level 1: This is the default setting which allows the scanner to operate fastest, while providing sufficient security in decoding “in-spec” UPC/EAN barcodes.
Level 2: If you failed to read poorly-printed or out-of-spec. barcodes in level 1, please select level 2. This is the most aggressive setting and may increase the misread.

The Supplement Scan Voting is the number of times the same UPC/EAN with 2/5 supplement digits has to be decoded before it is transmitted. It is helpful when decoding
a mix of UPC/EAN symbols with and without supplement digits. This function is effective when you select UPC/EAN with only 2 supplement digits, UPC/EAN with only 5
supplement digits or UPC/EAN with 2/5 supplement digits. The default value is Level 3. When you select higher level, it may impact the reading speed on poorly-printed,
low contrast or damage barcode labels.
