Barcode Scanning Beam Position
1. Remove any protective film from the window of barcode scanner.
2. Launch the
BarcodeDemo
program.
3. Point the laser beam at the barcode.
•
Adjust the distance according to the size of barcode.
•
The scan will stop automatically when the barcode is read, or after ten seconds, if
no barcode is detected.
Correct Scanning Beam Position
1. The smaller the size of the barcode, the closer the handheld needs to be. The effective
scanning range is 1.5-12 inches (40-300mm). If the unit fails to scan the barcode, adjust
the scan angle and distance.
2. The laser beam is a red thick line, when scanning a barcode.
Incorrect Scanning Beam Position
1. The laser beam must pass across the entire barcode.
2. It will not scan the barcode if the laser beam crosses only part of the barcode.
