6. Vedligeholdelse og pleje
- Rengør headsettet regelmæssigt med en blød, tør klud.
- Undgå at udsætte headsettet for ekstreme temperaturer, fugtighed eller direkte sollys.
- Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Opbevar headsettet et køligt og tørt sted, når det ikke er i brug.
- Undgå at tabe headsettet eller udsætte det for kraftige stød.
7. Fejlfinding
If you encounter issues with your LEVN Bluetooth Headset, please refer to the following common solutions:
- Headsettet tænder ikke: 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.
- Kan ikke parres med enhed:
- Sørg for, at headsettet er i parringstilstand (LED'en blinker blåt og rødt).
- Sørg for, at Bluetooth er aktiveret på din enhed, og at den er inden for en rækkevidde på 15 meter.
- Glem enheden fra dine Bluetooth-indstillinger, og prøv at parre igen.
- Genstart både headsettet og din enhed.
- 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.
- Ubehagelig pasform: Adjust the headband and rotate the earmuffs to find a comfortable fit. The headset is designed to be lightweight for extended wear.
