Opretholdelse
- Rensning: Rengør regelmæssigt ørepropperne og opladningsetuiet med en blød, tør klud. Brug ikke skrappe kemikalier eller slibende materialer.
- Ørespidser: Fjern og rengør ørepropperne med jævne mellemrum med mild sæbe og vand. Sørg for, at de er helt tørre, før du sætter dem på igen.
- Opbevaring: Når ørepropperne ikke er i brug, skal de opbevares i deres opladningsetui for at beskytte dem og holde dem opladede.
- Vandtæthed: The earbuds are water-resistant (sweatproof), making them suitable for sports and exercise. However, they are not designed for submersion in water. Avoid exposing them to excessive moisture.
Fejlfinding
- Ørepropper parrer ikke: Ensure both earbuds are in the charging case, then open the lid to activate pairing mode. Check your device's Bluetooth settings to ensure "E9" is selected.
- Kun én øreprop virker: Sæt begge ørepropper tilbage i opladningsetuiet, luk låget, og åbn det derefter igen. Dette nulstiller ofte forbindelsen mellem de to ørepropper.
- Ingen lyd: Kontrollér lydstyrken på både din enhed og øretelefonerne. Sørg for, at øretelefonerne er korrekt forbundet via Bluetooth.
- Opladningsproblemer: Verify that the USB-C cable is securely connected to both the charging case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean and free of debris.
