The reading angle is important factor.
Perform reading at the angle indicated in the figure. We recommend you
to set at approximately 2° to 3° angle from the perpendicular position.

Perform reading so that the entire symbol falls within the center of the red LED light.

The reader can still read a barcode even if the barcode is not in the center of the red LED light. However, if a part of the
barcode lies outside the LED light, the barcode cannot be read. Make sure the entire barcode is inside the LED light.
