6. Veaotsing
If you encounter issues with your device, refer to the following troubleshooting tips:
| Probleem | Võimalik põhjus | Lahendus |
|---|---|---|
| Seade ei lülitu sisse. | Aku tühi. | Laadige seade täielikult täis. |
| Ei saa Bluetooth-seadmega siduda. | Incorrect mode selected; device not in pairing mode; receiving device too far or not in pairing mode. | Ensure correct TX/RX mode. Press and hold multi-function button for 3 seconds to enter pairing mode. Ensure receiving device is in pairing mode and within 10m range. |
| Heli puudub või on halb helikvaliteet. | Incorrect cable connection; volume too low; interference; incompatible codec. | Check 3.5mm cable connection. Adjust volume on both devices. Move away from sources of interference. Ensure devices support SBC/AAC. |
| Audio delay/latency. | Bluetooth technology inherent latency; codec limitations. | While Bluetooth 5.2 reduces latency, some delay may still occur, especially with certain codecs or older receiving devices. This is often an inherent characteristic of wireless audio transmission. |
| Aku eluiga on oodatust lühem. | High volume usage; frequent pairing/disconnection; aging battery. | Reduce volume. Ensure full charge before use. Battery performance may degrade over time. |
| Cable is too short for my setup. | Standard cable length. | Kaalu ostmistasing a longer 3.5mm audio extension cable if needed for your specific setup. |
