Practice Targeting

When first connecting, allow approximately 3 seconds for the reader to initialize.
1. Hold the reader steady and point it at a test symbol.
2. Squeeze and hold the trigger.
3. Move the reader toward or away from the symbol in a fluid motion until the two side-by-side
blue bars converge in the middle of the symbol. When the reader is at the optimal distance
(about 4 inches or 10 cm), it will decode the symbol and will beep and vibrate while
emitting a green LED flash to indicate a Good Read. At this optimal distance, the two
blue bars should just be touching. Note that the bars overlap as you continue to draw
the reader away from the symbol.
4. If no decode occurs, slowly draw away from or move closer to the symbol while holding
the blue bars centered steadily on the symbol.
When the reader is closer to the symbol, you will
see two separate bars.

Targeting Suggestions
• Typically, you should not hold the reader exactly perpendicular to the symbol. Position
the reader at an angle to avoid specular reflection.
• Use smooth, fluid motion when targeting the symbol. Do not wave the reader side-to-side
or up-and-down, or attempt to sweep across a symbol, as sudden movements will create
blurred images.
• The reader is omnidirectional and can decode symbols in any orientation. When decoding
1D symbols, be sure that the entire symbol falls well within the field of view.
3-2
As you draw the reader away from the symbol, the
two bars converge. At the optimal distance, the
two bars should just be touching, as shown above.
