Reading Bar Codes
Turn the BHT on, bring the bar-code reading window to the bar code to be scanned,
and press the trigger switch. The BHT 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.
• 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.)
• To read bar codes wider than the readable area
of the bar-code reading window, pull the
bar-code reading window away from bar codes.
The BHT can read bar codes at a maximum
distance of 45 cm (17.7") from the bar-code
reading window, respectively. **
** Under the following conditions:
- Ambient illuminance: 500 lux (fluorescent lamp)
- ITF conforming to the UPC Shipping Container
Code
- PCS value: 0.9 or more
- Minimum narrow bar width: 1.2 mm min.
(47.2 mils min.)
• 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 bar 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.
• The light intensity of the illumination LED will vary depending upon the
scanning conditions and variation of its elements.
10. Information to user
DWBT003 is installed in the handy terminal, so DWBT003 has no user’s manual.
FCC user’s manual requirements that are FCC rule Part 15.21 and 15.105 are described on user’s

FCC WARNING : Changes or modifications not expressly approved by the party responsible fo
r
compliance could void the user’s authority to operate the equipment.
CAUTION : Radio Frequency Radiation Exposure
This equipment complies with FCC radiation exposure limits set forth for uncontrolled equipment and
meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C to OET65. This equipment
has very low levels of RF energy that it is deemed to comply without testing of specific
absorption ratio (SAR).
Co-location : This transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter.
