4.1. Bluetooth Wireless Connection

This mode allows you to connect the scanner to iOS, Android, or Windows Mobile devices without a USB receiver.

1. Turn on the scanner and ensure it is in Bluetooth mode.
2. On your device (e.g., smartphone, tablet), go to Bluetooth settings.
3. Search for available devices. The scanner should appear as "NETUM BLUETOOTH" or "C750".
4. Select the scanner to pair. Once connected, you can start scanning.

4.2. 2.4G Wireless Connection

This mode uses the included USB receiver for wireless connection to a computer or other compatible device.

1. Plug the 2.4G USB dongle (receiver) into an available USB port on your computer.
2. The computer should automatically recognize the device.
3. The scanner is now ready to transmit scanned data wirelessly to your computer.

4.3. USB Wired Connection

For a direct and stable connection, use the provided USB cable.

1. Connect one end of the USB cable to the scanner's USB Type-C port.
2. Connect the other end of the USB cable to an available USB port on your computer.
3. The scanner will function as a wired device and also charge its internal battery.

4.4. Wireless Pair (for 2.4G Wireless Mode)

If the scanner is not pairing correctly with the 2.4G USB receiver, follow these steps:

1. Unplug the USB receiver from your device.
2. Scan the following barcode with your scanner:

   

   The scanner will emit continuous beeps (di di di di...).
3. Plug the USB receiver back into your device. The beeping sound should stop immediately, indicating successful configuration.
4. If the beeping does not stop, repeat steps 1-3 and try plugging the USB receiver into a different USB port.

5. Operating Modes

The scanner has two main working modes: Normal Mode and Inventory Mode.

5.1. Normal Mode (Default)

In Normal Mode, scanned data is transmitted directly to your connected device via USB cable or USB receiver.

• Successful Scan: 1 beep, and data will be outputted on your device.
• Scan Failed: 3 beeps, and data will not be outputted on your device.

To ensure the scanner is in Normal Mode, scan the following barcode:

5.2. Inventory Mode

In Inventory Mode, scanned data is stored internally in the scanner's flash memory instead of being transmitted immediately. This is useful for collecting data when not connected to a host device.

To activate Inventory Mode, scan the following barcode:

5.3. Uploading Stored Data

After collecting data in Inventory Mode, you can upload it to your connected device.

To upload the data, scan the following barcode:

5.4. Total Entry Quantities

To check the total number of data entries stored in the scanner's memory, scan the following barcode:

5.5. Clear All Memory

Use with caution! This action will delete all data stored in the scanner's buffer memory.

To clear all stored data, scan the following barcode:

6. Idle Time Settings

You can configure the scanner's idle time before it enters sleep mode to conserve power. Scan the appropriate barcode below to set your preferred idle time.

7. Keyboard Language Settings

To ensure accurate data transmission in different countries or regions, configure the corresponding keyboard language. American English is set by default. If you use a US keyboard, you can ignore this setting.

To set the keyboard language, scan the appropriate barcode below:

For more language settings, please contact the vendor for the full electronic version of the manual.

8. Decoding Ability

The scanner demonstrates excellent decoding ability for various 1D and 2D barcodes, even from different surfaces and conditions.

9. User Tips

• For optimal scanning, ensure barcodes are clean and clearly visible. Digital barcodes on screens may require a CCD or 2D scanner model.
• If you need to add or remove an 'Enter' suffix after scanning, refer to the 'Common Function Barcodes' section in the full electronic manual or contact customer service for assistance.
• When using foreign languages, if you encounter garbled characters, adjust the keyboard language settings as described in Section 7.

10. Troubleshooting

10.1. Some barcodes cannot be read. Why?

• Dirty or Unclear Barcodes: Ensure the barcode is clean and clearly printed.
• Digital Barcodes: Digital barcodes displayed on phones, computers, or tablets can be read by CCD or 2D scanners. Ensure you are using the correct scanner type for these.
• Disabled Barcode Types: The setting for some barcode types may be off by default. You may need to activate a specific barcode type. Please contact Customer Service if you don't know the exact type of barcode.

10.2. Data cannot be sent to my computer. Why?

If you have turned off Normal Mode and are in Inventory Mode, the scanner stores your scans internally instead of instantly transmitting them. You need to scan the "Uploading the Data" barcode (Section 5.3) to send the stored codes to your connected device.

10.3. Messy code problem encountered while using other foreign languages.

The default language is English. Please refer to the "Keyboard Language Settings" section (Section 7) to change the setting to your desired language.

10.4. Scanner beeps continuously after pairing (2.4G Wireless).

If the scanner continues to beep after plugging in the USB receiver during pairing, try unplugging the receiver, scanning the "Wireless Pair" barcode again, and then plugging the receiver into a different USB port on your device.

11. Maintenance

• Cleaning: Use a soft, dry cloth to clean the scanner's exterior. For the scanning window, use a lint-free cloth and a mild cleaning solution if necessary. Avoid abrasive materials or harsh chemicals.
• Storage: Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge the scanner regularly, especially if it will be stored for an extended period.
• Firmware Updates: Check the manufacturer's website periodically for any available firmware updates to ensure optimal performance and compatibility.
