6. Maintenance
To ensure the longevity and optimal performance of your Fonicer Wireless Keyboard and Mouse Combo, follow these maintenance guidelines:

- Battery Replacement: Replace batteries promptly when performance degrades or devices stop responding. Always use new, good-quality AA batteries.
- Storage: When not in use for extended periods, turn off both devices and store them in a cool, dry place away from direct sunlight and extreme temperatures.
- Receiver Care: Keep the USB receivers free from dust and debris. When transporting, store them in their designated compartments to prevent loss or damage.
7. Troubleshooting
If you encounter issues with your Fonicer Wireless Keyboard and Mouse Combo, please refer to the following common solutions:
- Devices Not Responding:
- Ensure both the keyboard and mouse are turned on.
- Check if the batteries are correctly installed and have sufficient charge. Replace if necessary.
- Verify that the USB receiver (either USB-A or USB-C) is securely plugged into a working port on your device. Try a different USB port.
- Ensure the devices are within the effective wireless range (up to 33 feet or 10 meters) of the receiver.
- If using a USB hub, try connecting the receiver directly to the computer's port.
- Mouse Cursor Jumps or is Erratic:
- Clean the optical sensor on the underside of the mouse.
- Ensure you are using the mouse on a suitable surface (non-reflective, non-transparent).
- Check battery level and replace if low.
