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.
Touch scanning/long-range scanning (Touch Read)
You may select touch scanning or long-range scanning. The touch scanning is a
method in which you bring the bar-code reading window to a bar code to be scanned.
The long-range scanning allows you to read bar codes wider than the readable area of
the bar-code reading window by pulling the bar-code reading window away from bar
codes. (The BHT-5000 can read bar codes at a maximum distance of 20 cm (7.9") from
the bar-code reading window.)
If "Touch Read" is set to ON, the reading speed increases in touch scanning. In long-
range scanning, however, this setting may decrease the reading speed and efficiency
when the ambient illuminance is low or too high.
If "Touch Read" is set to OFF, the BHT-5000 can scan bar codes irrespective of the
ambient illuminance. This setting, therefore, is suitable for long-range scanning. Note
that the scanning speed will slightly decrease.
Decode level
You may set the recognition level. Decreasing the level value increases the bar-code
reading efficiency, but the BHT-5000 might misread low-quality bar codes (split or
stained). To the contrary, increasing the level value decreases the bar-code reading
efficiency, but it precludes almost all possibilities of misreading. The default "3" is
recommended.
NOTE
* For BHT-5000s having a 26-key pad, use F5 , F6 , F7 and F8 keys instead of
