6. Održavanje
Da biste osigurali dugotrajnost i optimalne performanse vaših TF-T28 slušalica, slijedite ove smjernice za održavanje:
- čišćenje: Redovno brišite slušalice i kutijicu za punjenje mekom, suhom krpom koja ne ostavlja dlačice. Izbjegavajte upotrebu jakih hemikalija ili abrazivnih materijala.
- Otpornost na vodu: The earphones are IPX4 rated, meaning they are resistant to splashing water and sweat. Do not submerge them in water or expose them to heavy rain. Dry them thoroughly if they get wet.
- Skladištenje: Kada se ne koriste, slušalice čuvajte u kutijici za punjenje kako biste ih zaštitili od prašine i oštećenja. Čuvajte ih na hladnom i suhom mjestu, dalje od ekstremnih temperatura.
- Punjenje: Koristite samo priloženi kabel za punjenje ili certificirani Type-C kabel. Izbjegavajte često prekomjerno punjenje ili potpuno pražnjenje baterije.
7. Otkrivanje problema
If you encounter any issues with your TF-T28 earphones, try the following steps:
- Nema problema sa zvukom/vezom:
- Provjerite jesu li obje slušalice napunjene.
- Isključite i uključite Bluetooth na uređaju, a zatim pokušajte ponovo upariti uređaj.
- Forget the "TRANSFORMERS TF-T28" device in your phone's Bluetooth settings and re-pair.
- Provjerite da li su slušalice unutar dometa prijenosa vašeg uređaja od 10 metara.
- Samo jedna slušalica radi:
- Vratite obje slušalice u kutijicu za punjenje, zatvorite poklopac, pričekajte nekoliko sekundi, a zatim ih ponovo izvadite. Ovo često resetuje vezu.
- Check if both earbuds have sufficient battery.
- Problemi s punjenjem:
- Provjerite je li kabel za punjenje sigurno spojen i na kućište i na izvor napajanja.
- Pokušajte s drugim kabelom za punjenje ili adapterom za napajanje.
- Očistite kontakte za punjenje na slušalicama i unutrašnjosti kućišta suhim pamučnim štapićem.
- Kontrole dodirom ne reaguju:
- Pazite da su vam prsti čisti i suhi kada koristite dodirne kontrole.
- Try restarting the earphones by placing them in the case and taking them out.
