Operating Instructions
Once the cable is connected and the software is launched, you can proceed with programming your radio:
- Software Recognition: The programming software should detect the connected radio via the USB cable. Confirm that the software recognizes the radio model.
- Read Radio Data: Use the software's function to read the current program settings and frequencies from your radio. This is often a good practice before making any changes.
- Modify Settings: Adjust frequencies, channel settings, and other parameters within the programming software interface as needed.
- Write to Radio: After making desired changes, use the software's "write" or "upload" function to transfer the new settings to your radio. Follow any on-screen prompts.
- Verify: After writing, it is recommended to read the radio data again to verify that the new settings have been successfully applied.
The cable enables stable and efficient programming of your radio by PC and through the microphone's keypad, offering ease of operation.
