2. Connect the other end of the USB cable to a USB port on your computer or host device.
3. The scanner will be recognized by your device and is ready for use.

6. Operation

6.1 Basic Scanning

To scan a barcode, ensure the scanner is connected to your device via one of the methods described in Section 5.2. Open a text editor, spreadsheet, or any application where you want the scanned data to appear. Point the scanner's window at the barcode and press the scan button. The scanner will emit a light beam and a beep (if enabled) upon successful decoding, and the barcode data will appear on your screen.

6.2 Decoding Ability

The NETUM C740 is equipped with a CCD sensor, allowing it to decode 1D barcodes from various surfaces, including:

• Printed paper labels
• Digital screens (computer monitors, smartphones, tablets)
• Barcodes through glass surfaces or plastic shrink wrap

6.3 Data Upload Modes

The scanner supports two primary data upload modes:

• Instant Upload Mode: Barcode data is transmitted directly to your connected device as soon as it is scanned. This is ideal for real-time data entry.
• Storage Mode: If the scanner is out of range or not connected, it can store scanned barcodes in its internal flash memory. It can store approximately 2000 Code128 barcodes. Data can then be batch uploaded to your device when a connection is re-established.

7. Maintenance

To ensure the longevity and optimal performance of your NETUM C740 barcode scanner, follow these maintenance guidelines:

• Cleaning: Regularly wipe the scanner's exterior with a soft, dry, lint-free cloth. For the scanning window, use a lens cleaning cloth or a soft cloth lightly dampened with a mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive materials.
• Battery Care: To maximize battery life, avoid fully discharging the battery frequently. If storing the scanner for an extended period, charge it to about 50% and store it in a cool, dry place. Recharge every few months to prevent deep discharge.
• Storage: Store the scanner in a clean, dry environment away from extreme temperatures, direct sunlight, and corrosive materials.
• Handling: Handle the scanner with care to prevent drops or impacts that could damage internal components.
