• Зүлгүүрийн цэвэрлэгч, уусгагчийг бүү ашигла.
• Чихэвчийг ашиглаагүй үед сэрүүн, хуурай газар хадгална.
• Чихэвчийг унагах эсвэл хүчтэй цохилтонд оруулахаас зайлсхий.

7. Алдаа засах

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

• Чихэвч асахгүй байна: 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.
• Төхөөрөмжтэй хослуулах боломжгүй:
  • Ensure the headset is in pairing mode (LED flashing blue and red).
  • Таны төхөөрөмж дээр Bluetooth идэвхжсэн, 15 метрийн зайд байгаа эсэхийг шалгаарай.
  • Блютүүт тохиргоондоо төхөөрөмжөө мартаад дахин холбож үзнэ үү.
  • Чихэвч болон төхөөрөмжөө дахин эхлүүлнэ үү.
• 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.
• Эвгүй тохирох: Adjust the headband and rotate the earmuffs to find a comfortable fit. The headset is designed to be lightweight for extended wear.
