• Over-Speed Alarm: Warns the driver when a pre-set speed limit is exceeded.
• Fatigue Driving Alert: Reminds the driver to take a break after extended driving periods.
• Engine Fault Code Reminder: Displays an alert if the vehicle's engine control unit (ECU) detects a fault.

7. Maintenance

To ensure the longevity and optimal performance of your C100 HUD, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to gently wipe the display and exterior of the unit. Avoid abrasive cleaners or solvents that could damage the surface.
• Storage: If the device is not in use for an extended period, disconnect it from the OBD2 port and store it in a cool, dry place away from direct sunlight and extreme temperatures.
• Avoid Impact: Protect the device from drops or impacts, as this can damage internal components or the reflective glass.

8. Troubleshooting

If you encounter issues with your C100 HUD, consider the following common solutions:

• No Display: Ensure the OBD2 cable is securely connected to both the vehicle's port and the HUD unit. Verify the vehicle's engine is running. Check if your car is OBD II compliant and made after 2010.
• Incorrect Readings: Confirm the correct unit (KM/H or MPH) is selected. If readings are consistently inaccurate, ensure the device is properly calibrated (refer to the quick start guide for calibration steps, if available).
• Double Image: The C100 is designed to prevent double images due to its built-in reflective glass. If you observe a double image, ensure the unit is positioned correctly and the display surface is clean.
• Alarms Not Functioning: Check the device settings to ensure specific alarms are enabled. Verify that the vehicle's sensors are functioning correctly.
