• 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 bar code becomes excessively strong. This can easily happen
when the reflecting 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 bar code reading procedure may differ depending upon the application used, so follow the application’s
manual.
• Before reading labels, clean them if stained.
• Avoid using the BHT in direct sunlight. The BHT might fail to read correctly.
• To read bar codes on curved surfaces, apply the bar-code reading window to the center of each ba
r
code at a right angle.
• If you pull the bar-code reading window away from bar codes, the actual scanning range will
become narrower than the range covered by the illumination LED.
• Do not use the BHT in the vicinity of radio equipment. The BHT may malfunction.
• The light intensity of the laser light or illumination LED will vary depending upon the scanning
conditions and variation of its elements.
• By using the “KbifCE” utility software, codes read by the BHT can be converted into keyboard data
to be transmitted to an application program. The utility software can be downloaded from our web
site (http://www.denso-wave.com
). For further details, refer to “2D Code Scanner/Barcode
Scanner Keyboard Interface with BHT-CE kbifCE User's Guide “ that comes with the software.
