6. Check the operational readiness of the scanner by pointing the scanning surface towards a flat surface
and pulling the trigger. A green target line as well as the red illumination should now be visible. Now scan
a sample label. The scanner emits an audible signal to confirm that the label has been read; if necessary,
the data are now passed on to the PC.
2.3 How do I scan codes?
This section explains the best way to scan codes:
The scanner must be held at a slight angle to the
bar code. (Do not hold the scanner at a right angle
to the bar code.)
The green LED line which serves as an alignment
aid should be positioned at the center of the code.
This ensures that the center point of the camera is
aligned with the code.
(The scanner will not be able to detect the label
correctly if it is not fully captured by the camera.)
The green LED line is smaller and narrower if the
scanner is held closer to the code. Small codes
should be read at a smaller reading distance. With
larger codes, the reading distance must be large
enough so that the camera can capture the
complete code.
