Configuring Your Scanner

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.
