Scanning Instructions

When the scanner is in the Manual scan mode, you can follow the steps below to scan a barcode:
1.
Press and hold the trigger. Then the scanner will project a red aiming beam.
2.
Aim the red beam across the center of barcode, as shown in Fig.1-12.
3.
Release the trigger when the red beam goes off. If the barcode is decoded successfully, the scanner
will beep and the decoded data will be sent to the Host.
Note: For the same batch of barcodes, the scanner will keep a very high success ratio in certain distance
which can be regarded as the optimal scanning distance.
