Reading 2D Codes And Bar Codes - Denso BHT-300BWB Operator's Manual

Reading 2D Codes and Bar Codes

Turn the BHT on, bring the reading window to a 2D code or bar code to be scanned,
and press the trigger switch. The BHT turns the marker beam (laser) and
illumination LED on to indicate the scanning range and scan the target code,
respectively.
When the BHT has read the code successfully, the indicator LED illuminates in
green and the marker beam goes off.

* The trigger switch function is
assigned to both of the M3
and M4 keys by default.
• If the BHT fails to read due to specular effects
or other factors, change the scanning angle of
the reading window or the distance from codes
as shown at right, and try it again. (Specular
effects occur when the reflection of the light
from the code becomes excessively strong.
This can easily happen when the reflecting
surface is polished or covered with vinyl.)
