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.
MARKER
You can select the marker ON/OFF mode from the following:
Normal: Normal mode driven by the trigger switch
Always: In addition to Normal mode, the laser light flashes for 30 seconds while waiting for reading to be
performed.
None: OFF mode
In Normal mode, the marker comes on at the same time as the illumination LED does.
Always mode consumes more current when compared with other modes, and therefore the operating
time is shorter. Do not use this mode unless necessary.
Minimum number of digits to be read for ITF, STF, or CODABAR
You can set the minimum number of digits to be read for ITF, STF, and CODABAR.
Setting a small number of digits increases the frequency of digit-missing reading or misreading
depending upon how to scan bar codes or the quality of bar codes. On the other hand, setting a large
number will diminish the possibility of those errors.
The setting range is from 2 to 20 for ITF, from 1 to 20 for STF, and from 3 to 20 for CODABAR. The
default is 4 for ITF and CODABAR, and 3 for STF.
