Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the FC5. Avoid using liquid cleaners or solvents, as they may damage the device.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Handle the FC5 with care to prevent physical damage. Avoid dropping the device or exposing it to excessive force.
- Connectivity Ports: Keep the USB-C and headphone ports free from dust and debris.
Troubleshooting
- No Sound Output:
- Ensure the FC5 is properly connected to both the source device and headphones.
- Check the volume level on both the FC5 and your source device. Increase gradually.
- Verify that the correct audio output device is selected on your computer or smartphone settings.
- If using an Android device, check if OTG connection is enabled in your phone's settings.
- Test with different headphones and a different source device to isolate the issue.
- Display Flickering:
- This may occur when the display is not fully lit. If functionality is not affected, it may be normal behavior.
- Ensure the device is receiving stable power from the source.
- Interference/Noise:
- Try using a different USB cable or connecting to a different USB port on your source device.
- Move the FC5 away from other electronic devices that might cause electromagnetic interference.
- Ensure your headphone cables are not damaged.
- Some smartphone designs (e.g., certain Google Pixel devices) may be prone to interference due to antenna lines. This is a characteristic of the phone, not the FC5.
- Device Not Recognized by Computer/Smartphone:
- For Windows 7/8, you might need to install specific drivers from the HiBy website. Windows 10 and Mac typically do not require drivers.
- Ensure the USB cable is securely connected.
- Try a different USB port or cable.
- Restart your computer or smartphone.
- Issues with Windows 11 (as reported by some users):
- While the FC5 is generally compatible, some specific system configurations or power delivery issues on certain Windows 11 devices (e.g., ROG Ally X) have been reported.
- Ensure your Windows 11 system is fully updated.
- Monitor device behavior closely. If unexpected shutdowns or errors occur, discontinue use with that specific device and contact HiBy support.
