Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Static or poor audio quality | FM frequency interference; weak signal. | Change to a different blank FM station on both the car radio and the transmitter. Avoid frequencies near strong broadcast stations. Ensure the device is securely plugged in. Some users report that adjusting the device's angle or re-inserting it can improve signal. |
| Device not powering on | Loose connection; car cigarette lighter socket issue. | Ensure the device is firmly plugged into the car's cigarette lighter socket. Check if the car's cigarette lighter socket is working (e.g., by testing with another device). |
| Bluetooth not connecting | Device not in pairing mode; incorrect device selected; Bluetooth interference. | Ensure the transmitter's LED is flashing (pairing mode). Forget "HY82" from your phone's Bluetooth list and try pairing again. Restart both the phone and the transmitter. |
| USB/TF card not playing music | Unsupported file format; corrupted files; card/drive not inserted correctly. | Ensure audio files are in MP3, WMA, or WAV format. Check if the USB drive or TF card is inserted fully and correctly. Try a different USB drive or TF card. |
| Key fob interference | FM frequency too close to key fob operating frequency. | If your car's key fob experiences issues, try changing the FM frequency on the transmitter to a different, less crowded part of the spectrum (e.g., if using 107.7 MHz, try 91.3 MHz as suggested by a user review). |
