7. Troubleshooting
- Earphones not pairing/connecting:
Ensure both earphones are charged. Turn off and on your device's Bluetooth. Forget "Lenovo LP75" from your device's Bluetooth list and try pairing again. - No sound from earphones:
Check the volume level on your connected device. Ensure earphones are properly connected via Bluetooth. Try playing different audio sources. - Translation not working or inaccurate:
Verify that the companion app is installed, open, and has the necessary permissions (microphone, internet). Ensure a stable internet connection for real-time translation. Check language settings within the app. - Sound leakage:
While the LP75 has a non-in-ear design, excessive volume can lead to sound leakage. Keep the volume at a moderate level. - Earphones not charging:
Ensure the charging cable is securely connected to both the case and the power source. Check if the charging case itself has power. Clean the charging contacts on both the earphones and the case.
