The LED lights on Opticon barcode scanners flash and blink in various colors, as well as beep, to notify you of status and potential errors. This guide outlines these patterns for easy interpretation and next steps.
Please remember that to pair a barcode scanner with an Entagged device, it must be one of the compatible models.
