Manutenção
Classificação de impermeabilidade (IPX7)
The speaker features an IPX7 waterproof rating, meaning it can be submerged in water up to 1 meter for 30 minutes. This makes it suitable for use in showers, by the pool, or during light rain. Ensure the charging port cover is securely closed before exposing the speaker to water.

Limpeza
Limpe o alto-falante com um suave, damp pano. Não utilize produtos de limpeza abrasivos ou solventes, pois estes podem danificar a superfície ou os componentes internos.
Cuidados com a bateria
Para prolongar a vida útil da bateria, evite descarregar completamente a caixa de som com frequência. Carregue-a regularmente, mesmo que não a utilize por longos períodos. Guarde-a em local fresco e seco.
Solução de problemas
- A caixa de som não liga: Ensure the speaker is fully charged. Connect it to a power source using the USB-C cable and allow it to charge for at least 30 minutes before attempting to power on again.
- Sem som: Check the volume level on both the speaker and your connected device. Ensure the speaker is properly paired via Bluetooth or that the TF card is correctly inserted and contains playable audio files.
- Não foi possível emparelhar via Bluetooth: Ensure the speaker is in pairing mode (usually indicated by a flashing LED). Turn off Bluetooth on your device and then turn it back on. If issues persist, try restarting both the speaker and your device.
- Stereo pairing not working: Ensure both speakers are powered off before attempting to pair them together. After they pair with each other, connect your device to the master speaker. Remember that TF card playback does not support stereo sound across two speakers.
- Problemas com danos causados pela água: While the speaker is IPX7 waterproof, always ensure the charging port cover is sealed tightly before exposure to water. If the speaker has been submerged, allow it to dry completely before attempting to charge or power on.
