Resolució de problemes
| Problema | Solució |
|---|---|
| Els auriculars no s'emparellan amb el dispositiu. | Ensure earbuds are fully charged. Turn off and on Bluetooth on your device. Forget "YD03" from your device's Bluetooth list and re-pair. Ensure earbuds are removed from the case to enter pairing mode. |
