Troubleshooting
This section addresses common issues you might encounter with your Chasing GLADIUS MINI S drone.
| Problem | Possible Cause | Solution |
|---|---|---|
| Drone does not power on. | Low battery or power connection issue. | Ensure the drone battery is fully charged. Check all power connections. |
| No video feed or signal loss. | Loose cable connection, Wi-Fi interference, or drone out of range. | Verify the wired connection between the controller and mobile device. If using Wi-Fi, ensure strong signal. Bring the drone closer to the surface if operating at maximum range. |
| Thrusters are not responding or are stuck. | Debris (sand, pebbles, aquatic plants) in thrusters. | Retrieve the drone and carefully inspect thrusters for obstructions. Clean thoroughly. The patented anti-stuck motor design minimizes this, but severe entanglement can still occur. |
| Poor image/video quality. | Dirty camera lens, low light, or water turbidity. | Clean the camera lens. Utilize the LED lights in low light. Operate in clearer water if possible. |
| Drone drifts or is difficult to control. | Strong currents, unbalanced trim, or thruster issue. | Avoid strong currents. Check app settings for trim adjustments. Inspect thrusters for proper function. |
