3. Operating the Barcode Scanner
3.1 Scanning Barcodes
- Ensure the scanner is powered on and connected to your device (either wirelessly or via cable).
- Open an application or text editor on your device where you want the scanned data to appear. Place your cursor in the desired input field.
- Aim the scanner's light beam at the barcode you wish to scan. Ensure the entire barcode is within the scanning area.
- Press the trigger button. A successful scan will be indicated by a beep and/or a light flash. The scanned data will appear in your application.
3.2 Supported Barcode Types
The GDA S20W scanner supports a wide range of both 1D (linear) and 2D (matrix) barcodes, including common types like EAN, UPC, Code 39, Code 128, QR Code, Data Matrix, and PDF417.
4. Maintenance and Care
4.1 Cleaning
To maintain optimal performance, keep the scanner clean. Use a soft, dry, lint-free cloth to wipe the exterior. For the scanning window, use a lens cleaning cloth. Avoid using abrasive cleaners, solvents, or excessive moisture, as these can damage the device.
4.2 Battery Care
The scanner is equipped with a 2000 mAh rechargeable battery. To prolong battery life, avoid fully discharging the battery frequently. Charge the device regularly, even if not in constant use. Do not expose the battery to extreme temperatures.
4.3 Storage
When not in use, store the scanner in a cool, dry place away from direct sunlight, high humidity, and extreme temperatures. Protect it from drops and impacts.
5. Troubleshooting Guide
- Scanner not powering on:
Ensure the battery is sufficiently charged. Connect the scanner to a power source using the USB cable and allow it to charge for a period before attempting to power it on again. - No scan output on device:
Verify that the scanner is properly connected to your device. If using wireless mode, ensure the USB receiver is securely inserted and the scanner is paired. If using wired mode, check the USB cable connection. Confirm that your cursor is in the correct input field on your device. - Scanner not pairing wirelessly:
Try re-inserting the USB receiver into a different USB port. Power cycle the scanner (turn it off and then on again). Refer to section 2.2 for detailed wireless connection steps. - Incorrect data output or unreadable barcodes:
Ensure the barcode is clean, undamaged, and within the scanner's optimal reading distance. The scanner supports various barcode types; if a specific type is not reading, it might require a configuration setting (usually done by scanning specific setup barcodes, which are not included in this manual).
If these steps do not resolve the issue, please contact customer support for further assistance.
