6. Operating Instructions
6.1 Basic Scanning Operation
Once powered on and connected, the BL-601 is ready to scan. The scanner operates automatically or can be triggered externally depending on its configuration.
- Ensure the barcode is within the scanner's field of view and focal range.
- The scanner will emit a laser beam to read the barcode.
- A successful read is typically indicated by a green LED and/or an audible beep (if configured).
- The decoded data is then transmitted to the host system via the connected interface.
