Operating the Scanner
Scanning Barcodes:
Once connected, aim the scanner's light at the barcode you wish to scan and press the trigger button. The scanner will emit a beep and the data will be transmitted to your connected device.
Trigger Modes:
- Key Trigger Mode: The scanning light is only active when the trigger button is pressed.
- Continuous Scan Mode: The scanning light remains on continuously when the scanner is powered, allowing for scanning without pressing the button.
- Auto-induction Mode: The scanning light is off until a barcode is presented in front of the scanner, at which point it automatically turns on to read the barcode.
Data Upload Modes:
- Instant Upload Mode: Barcodes are read and uploaded directly to the open file or application on your connected device.
- Storage Mode: All scanned barcodes are stored in the scanner's built-in memory. You can upload the stored data to your device in batch later. This is useful when operating out of wireless range.
