- **Storage**: Store the device in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
- **Battery Care**: For the built-in battery, avoid fully discharging it for extended periods. Recharge it periodically if not in use.
- **Physical Inspection**: Periodically check for any loose connections, damaged wires, or physical wear and tear.
- **Firmware Updates**: Check the manufacturer's website for any available firmware updates to ensure the best performance and compatibility.
5. Troubleshooting
If you encounter issues with your C7 MINI Plus system, refer to the following common troubleshooting steps:
5.1 No Power / Controller Not Turning On
- Ensure the controller is fully charged. Connect it to a Type-C charger and check the charging indicator.
- Verify the power button is pressed correctly.
5.2 No Control / Loss of Signal
- **Re-pair the controller and receiver**: Follow the pairing instructions in Section 2.3.
- **Check receiver power**: Ensure the MC210R receiver is receiving adequate power (DC 4.5-6V).
- **Check connections**: Verify all wires between the receiver and your model's components are securely connected.
- **Range**: Ensure you are within the specified control range (>800m for controller, >500m for receiver).
- **Interference**: The 2.4GHz chip is designed for enhanced anti-interference. However, strong local interference can still affect performance. Try operating in a different location.
5.3 Emergency Stop Activated
- If the emergency stop button has been pressed, the system will pause operation. Rotate the red emergency stop switch to the right to release it and resume control.
5.4 Low Voltage Alarm
- If a low voltage alarm is triggered, it indicates that the controller's internal battery or the connected device's battery is running low. Recharge or replace the battery as necessary.
