INVERT (Black-and-white inverted label reading function)
This function makes it possible to read white bars on a black background.
Activating this function might increase the frequency of bar-code reading errors. This function should
usually be set to OFF.
DECODE LEVEL
You can set the decode level. Decreasing the level value increases the bar-code reading efficiency, but
the BHT might misread low-quality bar codes (split or stained). To the contrary, increasing the level
value decreases the bar-code reading efficiency, but it will diminish the possibility of misreading.
The entry range of the level value is from 1 to 9 and the default is 4.
