5.1. Display Modes
The H600G provides various display modes to show different types of information. These modes typically include:
- Speed: Current driving speed.
- Altitude: Current altitude based on GPS data.
- Time: Current time obtained via GPS.
- Date: Current date obtained via GPS.
- Satellites: Number of connected satellites.
- Driving Time: Accumulated driving time since the last startup.
- Tripmeter: Accumulated driving distance since the last startup.
- Driving Direction: Current cardinal driving direction (e.g., N, S, E, W).

5.2. Gesture Switching
The device supports gesture recognition for switching between different display interfaces. Refer to the device's side buttons or integrated sensors for specific gesture controls. This allows for hands-free operation while driving.

5.3. Ambient Light
The H600G features surrounding atmosphere lights with 5 switchable colors (Green, Yellow, Blue, Red, Purple) to match your vehicle's interior or personal preference.

6. Display Interfaces
The H600G offers 7 distinct display interfaces, each providing specific information. These interfaces are designed for clarity and ease of reading.
| Interface No. | Display Content | Description |
|---|---|---|
| 1 | Compass + Speed | Shows current driving direction and speed. |
| 2 | Compass + Altitude | Shows current driving direction and altitude. |
| 3 | Compass + Time | Shows current driving direction and time. |
| 4 | Compass + Date | Shows current driving direction and date. |
| 5 | Compass + Satellites | Shows current driving direction and number of connected satellites. |
| 6 | Compass + Driving Time | Shows current driving direction and accumulated driving time. |
| 7 | Compass + Tripmeter | Shows current driving direction and accumulated driving distance. |

7. Maintenance
To ensure the longevity and optimal performance of your Irfora H600G, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the display and exterior of the device. Avoid using abrasive cleaners or solvents, which can damage the surface.
- Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Handle the device with care to prevent physical damage. Avoid dropping or subjecting it to strong impacts.
8. Troubleshooting
If you encounter issues with your Irfora H600G, refer to the following common problems and solutions:
- No Display/Power: Ensure the USB cable is securely connected to both the device and a functional USB port in your vehicle. Verify that the vehicle's ignition is on.
- Inaccurate Speed Reading: The H600G obtains actual speed from satellites, which may differ slightly from your car's dashboard speedometer. The H600G's reading is generally more accurate. It can be used as an overspeed alarm.
- Weak GPS Signal: If the GPS signal strength is less than 6, the device may issue an alarm or display inaccurate data. Ensure the device has a clear view of the sky and is not obstructed by metallic objects or tinted windows that might interfere with satellite reception. Move the vehicle to an open area if necessary.
- Display Not Changing: If the display is frozen or not responding to gestures, try disconnecting and reconnecting the USB power cable to restart the device.
