• Limpa os auriculares regularmente cun pano suave e seco.
• Evite expoñer os auriculares a temperaturas extremas, humidade ou luz solar directa.
• Non use produtos de limpeza ou disolventes abrasivos.
• Garda os auriculares nun lugar fresco e seco cando non estes en uso.
• Evite deixar caer os auriculares nin someterlos a impactos fortes.

7 Solución de problemas

If you encounter issues with your LEVN Bluetooth Headset, please refer to the following common solutions:

• Os auriculares non se acenderon: Ensure the headset is fully charged. Connect it to the Type C charging cable and allow it to charge for at least 10 minutes before attempting to power on again.
• Non se pode emparellar co dispositivo:
  • Ensure the headset is in pairing mode (LED flashing blue and red).
  • Make sure Bluetooth is enabled on your device and it is within the 15-meter range.
  • Esquece o dispositivo da túa configuración de Bluetooth e tenta vincular de novo.
  • Reinicia tanto os auriculares como o dispositivo.
• Poor microphone quality or background noise:
  • Ensure the microphone boom is positioned correctly, close to your mouth.
  • Verify that the AI Noise Cancellation feature is active (it is an inherent feature of the microphone).
  • Check your device's audio input settings to ensure the headset microphone is selected as the default input device.
• Audio in mono during calls/gaming: This is a limitation of Bluetooth technology when using the microphone for communication (Hands-Free Profile). To achieve stereo audio, the microphone typically needs to be inactive. If stereo audio with an active microphone is critical for your use case (e.g., gaming), consider a headset that uses a 2.4GHz wireless protocol instead of Bluetooth.
• Axuste incómodo: Adjust the headband and rotate the earmuffs to find a comfortable fit. The headset is designed to be lightweight for extended wear.
