Setup
1. Charging the Scanner

2. Connecting the Receiver (Wireless Mode)
- Insert the USB receiver into an available USB port on your computer or host device.
- The system will automatically install the necessary drivers.
- The scanner should automatically pair with the receiver. A successful connection is usually indicated by a specific sound or light on the scanner.
3. Bluetooth Pairing (Bluetooth Mode)
To connect via Bluetooth without the receiver:
- Ensure the scanner is powered on.
- On your host device (computer, tablet, smartphone), enable Bluetooth and search for available devices.
- Select "Klanata S20W" (or similar device name) from the list to pair.
- A successful connection will be confirmed by an audible beep or indicator light on the scanner.
Operating Instructions
1. Power On/Off
To power on the scanner, press and hold the trigger button for a few seconds until you hear a beep and the indicator light illuminates. To power off, press and hold the trigger button again until the scanner powers down.
2. Scanning Barcodes
- Point the scanning window at the barcode you wish to scan.
- Press the trigger button. A red aiming beam will appear.
- Position the aiming beam to cover the entire barcode.
- Upon a successful scan, the scanner will emit a beep and the indicator light will flash. The decoded data will be transmitted to your connected device.
3. Scanning 1D and 2D Codes
The Klanata S20W is capable of decoding both 1D (linear) and 2D (matrix) barcodes, including QR codes, PDF417, and Data Matrix. Ensure the entire code is within the aiming beam for optimal scanning.
Maintenance
1. Cleaning
Regularly clean the scanning window with a soft, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaning solution. Do not use harsh chemicals or abrasive materials, as these can damage the scanning window.
2. Battery Care
To prolong battery life, avoid fully discharging the battery frequently. Charge the scanner when the low battery indicator appears. If the scanner will not be used for an extended period, charge it to approximately 50% and store it in a cool, dry place.
3. Storage
Store the scanner in a clean, dry environment away from extreme temperatures, direct sunlight, and corrosive materials. Protect it from drops and impacts.
