In order to obtain a good reading effect, the aiming beam projected by the viewfinder should be aimed at the center of the barcode, but it can be aimed in any direction for reading. 2. Aim the scanner at the bar codes and press the trigger so that the aiming beam is in the middle of the bar code. 3. The closer the scanner is to the barcode, the smaller the aiming beam; the further away the scanner scanner is from the barcode, the larger the aiming beam. If the barcode is small, the scanner should be close to the barcode; if the barcode is large, the scanner should be farther away from the barcode, so that it is easier to read the barcode correctly. 4. If the bar codes is highly reflective (for example, coated), you may need to tilt the scanner scanner at an angle to successfully scan the bar code. 1、2.4G wireless transmission, 20?30 meters transmission range(open space). The operating distance is short and the bit error rate is low. 2、Strong storage capacity, up to 4,000 barcode data can be stored.
