4 Setting Up and Using the Scanner
Follow the steps below to connect and get the scanner up and communicating with its host.
1. Attach the HP Retail Integrated Barcode Scanner to the host device.
2. Configure the Interface, if necessary (refer to Configuring the Interface on page 9 ).

Using the Scanner
The scanner functions by capturing the barcode (object) image and decoding the codes. The bar
code scanner is set by default for Automatic Object Sense Read Mode that activates the aiming
system on object motion. The aiming system indicates the field of view as an indication of where the
bar code or object should be located for decoding.

Figure 4-2 Relative Size and Location of Aiming System Pattern
A red illumination lights up the label. The field of view indicated by the aiming system will be smaller
when the scanner is closer to the bar code and larger when it is farther from the code. Symbologies
with smaller bars or elements (mil size) should be read closer to the unit. Symbologies with larger
bars or elements (mil size) should be read farther from the unit.
If the aiming system is centered and the entire bar code is within the aiming field, you will get a good
read. Successful reading is signaled by an audible tone plus a good-read green spot indication.
Refer to the HP Retail Integrated Barcode Scanner Programming Reference Guide (PRG) for more
information about this feature and other programmable settings.
