- 2.4Ghz Wireless Connection:
- Insert the 2.4G USB dongle into an available USB port on your computer or device.
- The scanner will automatically pair with the dongle. No driver installation is required.
- Maximum transmission range is approximately 100m (330ft) in a barrier-free environment and 30m (99ft) under obstacles.
- Bluetooth Connection:
- Ensure your device (e.g., tablet, smartphone, computer) has Bluetooth enabled.
- Scan the Bluetooth pairing barcode (refer to the physical manual for specific barcode).
- On your device, search for and select the scanner from the list of available Bluetooth devices.
- Maximum transmission range is approximately 50m (164ft) in a barrier-free environment and 20m (66ft) under obstacles.
- USB 2.0 Wired Connection:
- Connect the scanner directly to your computer via the provided USB cable.
- The scanner will function as a wired device and will also charge simultaneously. No driver installation is required.
3.3 Compatibility
The scanner is compatible with a wide range of operating systems and devices:

- Operating Systems: Windows XP/7/8/10, Mac OS, iOS, Android, Linux.
- Devices: Desktop computers, Laptops, POS systems, Smartphones, Tablets.
4. Operating Modes
The NetumScan 2D-G offers flexible scanning and data handling modes to suit different operational needs.
4.1 Scanning Modes

Image 4: Depicts the three scanning modes: Trigger mode (manual scan), Continuous mode (automatic, constant scanning), and Storage mode (scanner storing data for later upload).
- Trigger Mode (Manual Scan): Press the trigger button to scan each barcode individually.
- Continuous Mode: The scanner continuously emits a scan beam, reading barcodes as they pass within its field of view without needing to press the trigger.
- Auto-sensing Scan: The scanner automatically detects a barcode in its field of view and scans it without manual trigger activation. Note: Some special barcodes may require specific settings to enable this function. If the self-sensing scanning function is inactive, please refer to the manual's troubleshooting section or contact support.
4.2 Data Transmission Modes
- Instant Upload Mode: Barcodes are transmitted to the connected device immediately after scanning.
- Storage Mode: Barcodes are stored in the scanner's internal memory. This mode is useful when operating out of wireless transmission range. Data can be uploaded to your device once you re-enter the transmission range. The scanner can store up to 100,000 barcodes.
5. Scanning Capabilities
The NetumScan 2D-G is equipped with a 32-bit CPU, providing a decoding speed of up to 350 scans per second. It can read a wide array of 1D and 2D barcode symbologies, even those that are smudged, damaged, fuzzy, or reflective.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your scanner.
6.1 Cleaning
- Use a soft, dry cloth to clean the scanner's exterior.
- For the scanning window, use a lens cleaning cloth or a soft cloth lightly dampened with a mild, non-abrasive cleaner. Avoid harsh chemicals.
6.2 Durability and Protection
The scanner features a professional anti-shock design, made from ABS+PC materials with a silicone protective cover. This provides high shock resistance and protects against scratches and friction from falls up to 6.57 feet (2 meters). Its IP54 rating ensures protection against dust and moisture.
