- Point -
inverted labels, however, there is higher chance of barcodes being incorrectly read.
This should normally be set to "OFF" (black/white inverted label reading disabled).
 "2: DECODE LEVEL": Decode level
Set the decode level (barcode reading tolerance level).
Press [ ] to decrease the setting value and [ ] to increase the setting value.
Decode level entry range: 1 - 9
Decreasing the level increases the barcode reading efficiency, however, the BHT may incorrectly read
low-quality (split or stained) barcodes.
On the other hand, increasing the level decreases the barcode reading efficiency, but will decrease the
possibility of incorrect reading.
