• If the BHT fails to read due to specular effects or other
factors, change the scanning angle of the reading win-
dow or the distance from codes as shown at right, and
try it again. (Specular effects occur when the reflec-
tion of the light from the bar code becomes exces-
sively strong. This can easily happen when the re-
flecting surface is polished or covered with vinyl.)
• The laser light indicates the scanning range as a guide.
The indicated scanning range will deviate a little bit
from the actual one. Keep the BHT so that the laser
light comes to almost the center of the bar code height.
• The BHT can read bar codes at a maximum distance of 40 cm (15.7")* from the
reading window. (*For details about the scanning conditions, refer to Appendix
A.)
• The bar code reading procedure may differ depending upon the application
used, so follow the application's manual.
BHT-100B
Turn the BHT power on, bring the bar-code reading window to the bar code to be
scanned, and press the trigger switch. The BHT-100B emits a laser light to indicate the
scanning range and turns on the illumination LED to scan the bar code.
When the BHT has read the bar code successfully, the indicator LED will illuminate in
green.
