Reading techniques

1. Press and hold the trigger, the scanner projects a green LED square which allows positioning the barcode within its field of view, and turns on the white LED for illumination.
2. When reading a barcode, the green LED square will be smaller when the scanner is closer to the barcode and larger when it is farther from the barcode. Please hold the scanner at an appropriate distance from the barcode, and center the green LED square on the barcode.
3. On a successful barcode reading, the scanner will beep once, and the green LED square and white LED will be turned off. Then the scanner transmits barcode message to the host.
