Before using the programming cable, ensure you have the correct programming software for your specific QYT mobile radio model installed on your computer. Drivers for the USB cable are typically included with the programming software or can be downloaded from the radio manufacturer's official website.

- Verify Installation: After installation, connect the USB end of the cable to an available USB port on your computer. Open your computer's Device Manager (Windows) or System Information (macOS) to confirm that the cable is recognized and the drivers are correctly installed, typically appearing as a new COM port.
2.2 Connecting the Cable
