Operating Instructions

The HUD offers various functions and display modes:

Interface Modes

The device provides 6 different interface modes to display various information. Use the wave button to cycle through these modes and select your preferred display:

• Interface 1: Speed, RPM, Water Temperature, Voltage
• Interface 2: Speed, Time
• Interface 3: Speed, Single Driving Distance

Unit Switching

Speed units can be switched between Kilometers per Hour (KM/H) and Miles per Hour (MPH). When MPH is selected, related units like water temperature, one-way driving distance, and fuel consumption will automatically switch to Fahrenheit (°F), Miles, and Miles Per Gallon (MPG) respectively.

Alarm Functions

The device includes several alarms to enhance driving safety:

• Speed Alarm: Flashes to alert when a preset speed limit is exceeded.
• Fatigue Driving Alarm: Reminds the driver to take a break after extended driving periods.
• Engine RPM Fault Alarm: Alerts to abnormal engine RPM.
• Low Voltage Alarm: Indicates when the battery voltage drops below a set value.
• Water Temperature Alarm: Warns if the engine water temperature exceeds a safe limit.

Features

The KAOLALI L3 OBD2 Head-Up Display incorporates several key features for an optimal user experience:

• Automatic Brightness Adjustment: The display automatically adjusts its brightness based on ambient light conditions, ensuring clear visibility during both day and night driving without manual intervention.
• 3D Reflection Technology: This technology projects information onto a transparent display board, providing a clear, reflection-free view and eliminating double images often associated with traditional HUDs. The brightness is increased by 20% to maintain clarity even in direct sunlight.

Maintenance

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

• Cleaning: Keep the display panel clean and free from dust. Use a soft, dry, lint-free cloth for cleaning. Avoid using harsh chemicals, abrasive materials, or excessive moisture, as these can damage the display surface.
• Storage: When not in use for extended periods, store the HUD in a cool, dry place away from direct sunlight and extreme temperatures.

Troubleshooting

If you encounter issues with your KAOLALI L3 OBD2 Head-Up Display, please refer to the following common problems and solutions:

• Display Not Turning On:
  Ensure the OBD2 cable is securely connected to both the HUD unit and your vehicle's OBD2 port. Verify that your vehicle's ignition is in the 'ON' position or the engine is running.
• Inaccurate Speed Reading:
  The HUD's speed reading may slightly differ from your vehicle's speedometer due to various factors, including tire size variations or vehicle manufacturer settings. Most HUDs allow for a speed calibration adjustment. Please refer to the detailed user manual (physical copy) for specific calibration instructions if available, or contact customer support for guidance.
• Double Image or Blurry Display:
  Ensure the transparent reflector on the HUD unit is clean and free from smudges or dust. Adjust the viewing angle of the HUD unit on your dashboard. While the 3D reflection technology is designed to minimize this, extreme lighting conditions or improper placement can sometimes affect clarity.
• HUD Powers Off While Driving:
  Check the OBD2 cable connection for looseness. Ensure your vehicle's OBD2 port is functioning correctly. This could also indicate a low voltage condition in your vehicle's electrical system, triggering the low voltage alarm.
