3.After you type in your name and location, click OK. The following message appears:
Note: When using the external QC3800V linear imager, it does not report ISO/ IEC reflectance parameters; therefore no calibration is necessary or possible.
Scanning Properly Using the QC3800V Linear Imager:
1.The best reading position for the QC3800V linear imager is 6 inches (150mm) from the surface of the bar code to the face of the scanner, with an angle of incidence of 15 degrees from perpendicular. At this orientation, the system performance approximates an average circular aperture size of .006 to .008 inches (.152 to .203 mm). Extreme variations from this orientation may negatively affect the accuracy of some parameter results.
2.Scanning is initiated by depressing the trigger on the linear imager.
3.Listen for an audible tone. When the unit scans and decodes a bar code, it emits a single beep.
•If the unit cannot decode a bar code after a trigger pull, nothing happens.
•After a successful decode, with a result that passes the minimum acceptable grade, the unit emits another beep of the same tone.
•A decode that fails to receive a grade above the minimum requirement causes the unit to emit a beep of a different tone.
