B-10 Barcode Reader
B.2.4 Scanning in Hand-Held Mode
1. Ensure all connections are secure (see the appropriate host chapter.)
2. Aim the digital imager reader at the barcode.
3. When the digital imager reader senses movement, in its default Auto Aim trigger mode,
it projects a red LED dot which allows positioning the barcode within the field of view.
If necessary, the digital imager reader turns on its red LEDs to illuminate the target
barcode.
4. Center the symbol. Be sure the entire symbol is within the rectangular area formed by
the illumination LEDs.
5. Hold the trigger until the digital imager reader beeps, indicating the barcode is
successfully decoded.
NOTE: Steps 2 - 4 may be required to repeat on poor quality or difficult barcodes.
The aiming pattern is smaller when the digital imager reader is closer to the symbol
and larger when it is farther from the symbol. Scan symbols with smaller bars or
elements (mil size) closer to the digital imager reader, and those with larger bars or
elements (mil size) farther from the digital imager reader.
The digital imager reader can also read a barcode presented within the aiming dot
not centered. The top examples in show acceptable aiming options, while the bottom
examples cannot be decoded.
