4.3 Scanning from Electronic Screens

The NS-NT91 is capable of reading barcodes directly from electronic screens, such as smartphones and tablets, making it versatile for modern applications.

4.4 Scanner Sound Settings

The scanner provides audible feedback upon successful scans. Refer to the Quick Start Guide or the manufacturer's website for specific instructions on adjusting or muting the scanner's sound.

5. Maintenance

To ensure the longevity and optimal performance of your NetumScan NS-NT91 scanner, follow these maintenance guidelines:

• 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 cleaner. Avoid harsh chemicals that could damage the plastic.
• Storage: Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Handling: Avoid dropping the scanner or subjecting it to strong impacts, despite its robust design.

6. Troubleshooting

If you encounter issues with your NS-NT91 scanner, refer to the following common troubleshooting steps:

• Scanner Not Responding: Ensure the USB cable is securely connected to both the scanner and the host device. Try plugging the scanner into a different USB port or a different computer to rule out port or host device issues.
• No Barcode Read: Verify that the barcode is clean, undamaged, and within the scanner's field of view. Adjust the distance and angle of the barcode relative to the scanner. Ensure the correct scanning mode is active for your application.
• Incorrect Data Output: Check the host device's input settings to ensure they are compatible with the scanner's output. Refer to the Quick Start Guide for programming barcodes to configure scanner settings if necessary.
• Intermittent Scanning: Ensure there are no obstructions around the scanning window. Check for any loose cable connections.
