Troubleshooting
If you encounter issues with your Skullcandy Indy Fuel earbuds, try the following solutions:

- Ensure both earbuds are removed from the charging case and are in pairing mode (flashing red/blue on the left bud).
- Forget/Remove "Indy Fuel" from your device's Bluetooth settings.
- Place both earbuds back into the charging case, close the lid for a few seconds, then open it again.
- Repeat the pairing process.
- One Earbud Not Working:
- Place both earbuds back into the charging case and ensure they are properly seated and charging (red light).
- Remove them from the case simultaneously. They should automatically re-sync.
- If the issue persists, perform a factory reset (refer to the user guide for specific steps, often involving holding buttons while in the case).
- Audio Cutting Out/Bluetooth Disconnection:
- Ensure your device is within the 10-meter Bluetooth range.
- Minimize obstacles between your device and the earbuds.
