Selecting "4: BARCODE" on the SET SYSTEM menu
calls up the screen shown at left.
Reversed is the current setting.
1 INVERT : Activates or deactivates the
black-and-white inverted la-
bel reading function.
2 TOUCH READ : Switches to the touch scan-
ning (ON) or long-range
scanning (OFF).
3 DECODE LEVEL : Sets the decode level.
Select a desired item by using the numerical keys
or F5 and F6 keys, and then select a desired
setting by using the F7 and F8 keys.
To increase the decode level, press the F8 key; to
decrease it, press the F7 key.
Press the ENT key.
To return to the SET SYSTEM menu, press the C
key.

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.
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-6000 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 (DECODE LEVEL)
You may set the recognition level. Decreasing the level value increases the bar-code
reading efficiency, but the BHT-6000 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 setting range of the level value is from 1 to 9 and the default is 3.
