9. Vianmääritys
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| Moduuli ei käynnisty. | Ei virtaa, väärä äänenvoimakkuustage, faulty power source. | Check power connections. Ensure power source is 3.5V-5V DC. Try a different power adapter or battery. |
| Ei äänituloa/-lähtöä. | Incorrect audio cable connection, module not paired, incorrect mode. | Verify audio cables are securely connected. Ensure module is paired with the correct device. Check if the module is in the correct Transmit/Receive mode. |
| Poor Bluetooth connection or short range. | Antenna not connected, obstacles, interference. | Ensure the external antenna is securely attached. Reduce obstacles between the module and the paired device. Avoid placing near Wi-Fi routers or other strong RF sources. |
| Ei voi muodostaa pariliitosta laitteen kanssa. | Module not in pairing mode, device too far, interference, previously paired device. | Ensure the module is in the correct pairing mode (check indicator lights). Bring devices closer. Turn off Bluetooth on other nearby devices. Try clearing previous pairings on both devices. |
| Sound quality is poor (static, distortion). | Weak signal, interference, low quality audio source. | Improve signal strength by reducing distance or obstacles. Check audio source quality. Ensure audio cables are not damaged. |
