5. Operating Instructions

5.1 Dual Operating Modes

The A91 supports two primary operating modes: OBD-II and GPS. The device will automatically detect the mode based on vehicle connection and signal availability.

OBD Mode (On-Board Diagnostics)

Compatible with most OBD-II vehicles (manufactured after 2008). This mode provides comprehensive real-time data from your vehicle's onboard computer. Supported communication protocols include SAE J1939, CAN Bus, K-Line (ISO 11898 & ISO 9141 compliant).

Displayed Data Points: Speed, RPM, Coolant Temperature, Voltage, Fuel Level, Instantaneous Fuel Consumption (INS Fuel), Average Fuel Consumption (AVG Fuel), Turbo Pressure, Engine Load, Oil Temperature, Continuously Variable Transmission (CVT) Temperature, Exhaust Gas Temperature (EGT), Outside Temperature, Fuel Pressure, Oil Pressure, State of Charge (SOC), Atmospheric Pressure, Intake Air Temperature (IAT), Air-Fuel Ratio (AFR), Throttle Position, Custom Data (1-5), Driving Time, Trip Distance, Odometer (ODO), Performance Test, Max-speed, Average Speed, PID (Parameter ID) data.

GPS Mode

This mode is vehicle-agnostic and acquires data via satellite signals. It supports GPS (USA), BeiDou (China), and GLONASS (Russia) global navigation satellite systems.

Displayed Data Points: Speed, Time, Date, Driving Direction, Altitude, Positional Accuracy, Number of Satellites, Latitude & Longitude (LAT&LAN).

5.2 Interface Themes

The A91 offers 9 distinct interface themes to personalize your display. You can switch between these themes to find the layout that best suits your preferences and driving needs.

5.3 Gesture Recognition and Touch Buttons

The A91 features a built-in photoelectric sensor for millisecond-fast gesture recognition, allowing you to wave your hand to switch between interfaces. Additionally, touch buttons provide precise control for navigating menus and adjusting settings.

5.4 Performance Testing

The A91 can perform and record various performance tests, including:

• 0-100km/h Acceleration Test
• 100-0km/h Braking Test
• 0-200m Acceleration
• 0-400m Acceleration
• 60-160m Acceleration

These tests provide real-time data and recording for acceleration time, distance, and current speed, as well as braking time and distance.

5.5 Alarm Warnings

The A91 provides configurable alarm warnings to alert you to critical vehicle conditions:

• Speed Alarm
• RPM Alarm
• Coolant Alarm
• Voltage Alarm
• Oil Temperature Alarm
• Exhaust Gas Temperature (EGT) Alarm
• Rest Reminder (Driver Fatigue)

These alarms can be toggled ON/OFF and their parameters adjusted within the settings menu.

5.6 Settings Menu

Access the settings menu to customize various aspects of your A91 HUD:

• Speed Set: Configure speed choice (OBD/GPS), speed unit, and set up to 4 speed warnings.
• Adjust: Fine-tune RPM, speed, turbo, voltage, and mileage adjustments.
• Fuel Set: Adjust fuel calculation method, fuel unit (L/100KM), swept volume, and fuel type (GAS).
• Alarm Set: Toggle alarm warnings ON/OFF and set specific thresholds for speed, RPM, coolant, oil temp, and exhaust temp.
• System Set: Adjust brightness (auto-dimming with 11 adjustable levels, or manual), display contrast, gesture sensor (ON/OFF), temperature unit, and pressure unit.
• Special Features: Access model-specific features and define up to 5 custom functions.
• DTC: View Diagnostic Trouble Code (DTC) status and clear DTCs.

5.7 Display Clarity

The A91 features an auto-dimming display with a built-in ambient light sensor, automatically adjusting brightness for optimal visibility in various lighting conditions. Manual mode offers 11 adjustable levels for personalized comfort.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the display screen and the device body. Avoid using abrasive cleaners or solvents that could damage the surface.
• Sensor Care: Ensure the ambient light sensor (located on the device) and the gesture recognition sensor are kept clear of dust and obstructions for optimal performance.
• Cable Management: Periodically check the connector cable for any signs of wear or damage. Ensure it remains securely connected and properly routed to prevent interference or accidental disconnection.
• Storage: If storing the device for an extended period, disconnect it from the vehicle and store it in a cool, dry place away from direct sunlight.

7. Troubleshooting

• Device Does Not Power On:
  • Ensure the OBD-II cable is securely connected to both the A91 unit and the vehicle's OBD-II port.
  • Verify that your vehicle's ignition is on.
  • Check if your vehicle is compatible (manufactured after 2008).
  • Test the OBD-II port with another compatible device if possible to rule out a vehicle issue.
• No Data Displayed in OBD Mode:
  • Confirm the vehicle is OBD-II compliant and manufactured after 2008.
  • Check the OBD-II cable connection.
  • Some older OBD-II vehicles or specific models might have compatibility issues. Try switching to GPS mode if OBD data is unavailable.
• Inaccurate Speed/Data in GPS Mode:
  • Ensure the device has a clear view of the sky to receive satellite signals. Obstructions like tunnels or tall buildings can affect accuracy.
  • Allow a few minutes for the GPS to acquire a stable signal after startup.
• Gesture Recognition Not Responding:
  • Ensure the gesture sensor is clean and unobstructed.
  • Check the 'Gesture Sensor' setting in the System Set menu to ensure it is enabled.
  • Perform gestures clearly and within the sensor's range.
• Alarms Not Functioning:
  • Verify that the specific alarm (e.g., Speed Alarm, RPM Alarm) is toggled 'ON' in the 'Alarm Set' menu.
  • Check the set threshold values to ensure they are appropriate for your driving conditions.

8. User Tips

• Vehicle Compatibility: Remember that this product is primarily designed for cars manufactured after 2008. Older vehicles may not be fully compatible with the OBD-II features.
• Interface Customization: Explore all 9 interface themes to find the one that provides the most comfortable and informative display for your driving style. You can also define up to 5 custom functions in the settings.
• "Color Name" in Product Options: If you encounter product options labeled with country names (e.g., "Korean", "Japanese", "Russian", "Thai"), these typically refer to the language version of the device's firmware and display, not a physical color. Choose the option corresponding to your preferred language.
• Optimal Brightness: While the auto-dimming feature works well, you can manually adjust the brightness through 11 levels in the System Settings for personalized visual comfort, especially in challenging lighting conditions.
