[4.4] Setting the special bar-code scanning parameters
Black-and-white inverted label reading function (INVERT)
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 can usually be set to OFF.
DECODE LEVEL
You may 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 setting range of the level value is from 1 to 9 and the default is 4.
