3. Connect Power
- Connect one end of the USB-A to USB-C power cord to the dash cam's USB-C port.

Operating Instructions
Automatic Recording
Once powered on, the GKU D200 Dash Cam will automatically begin recording. The indicator light will typically show a solid color or flash to indicate recording status.
Loop Recording
The dash cam records video in continuous loops. When the MicroSD card is full, the oldest unlocked files will be overwritten by new recordings. This ensures continuous recording without manual intervention.
G-Sensor (Emergency Recording)
The built-in G-Sensor detects sudden impacts or collisions. When triggered, it automatically locks the current video segment, preventing it from being overwritten by loop recording. These locked files are stored in a separate folder on the MicroSD card.

Night Vision with WDR
The dash cam features advanced WDR (Wide Dynamic Range) technology and an F1.8 aperture with a 6-glass lens to enhance video clarity in low-light conditions and at night. This helps balance exposure and capture details in both bright and dark areas of the frame.

Troubleshooting
| Problem | Possible Solution |
|---|---|
| Dash cam does not power on. | Check the power cable connection. Ensure the vehicle's 12V power outlet is functioning. Try a different power source if available. |
| Recording stops unexpectedly. | Ensure the MicroSD card is properly inserted and not full (loop recording should prevent this unless locked files fill the card). Format the MicroSD card. Use a high-speed (Class 10 or U3) MicroSD card. |
| Video footage is blurry or unclear. | Clean the dash cam lens and your windshield. Ensure the protective film has been removed from the lens. |
| WiFi connection issues. | Ensure the dash cam's WiFi is enabled. Restart both the dash cam and your smartphone. Re-enter the WiFi password. Ensure you are within range. |
| G-Sensor is too sensitive/not sensitive enough. | Adjust the G-Sensor sensitivity setting via the app. |
