7. Fejlfinding
| Problem | Mulig løsning |
|---|---|
| Statisk eller dårlig lydkvalitet | Ensure the FM frequency on the transmitter matches an empty frequency on your car radio. Try different empty frequencies. Adjust the volume on both your phone and car radio. |
| Bluetooth forbinder ikke | Make sure Bluetooth is enabled on your phone and "BC87" is selected. Restart the transmitter and your phone, then try pairing again. Ensure the device is within the 10M wireless range. |
| Enheden tænder ikke | Check if the car's cigarette lighter socket is receiving power (e.g., car ignition is on). Ensure the transmitter is fully inserted into the socket. |
| Langsom opladning eller ingen opladning | Verify that your charging cable is not damaged and is compatible with fast charging. Ensure your device supports PD or QC 3.0 for optimal speeds. Check if the car is running to provide sufficient power. |
| Call quality issues (echo, unclear voice) | Ensure the dual microphones are not obstructed. Reduce background noise in the car if possible. The CVC8.0 noise reduction should minimize most issues. |
