4. Maintenance
Proper maintenance is crucial for the longevity and performance of your Gladius Mini.
4.1 Post-Operation Care
- Rinse Thoroughly: After each use, especially in saltwater, thoroughly rinse the drone, tether, and base station with fresh water. This helps prevent corrosion and salt buildup.
- Dry Completely: Ensure all components are completely dry before storage. Use a soft cloth to wipe down surfaces.
- Inspect Propellers: Regularly check the propellers for any debris, sand, or damage. Clean them gently if necessary.
- Lubricate Seals: Periodically inspect and lubricate any rubber seals or O-rings to maintain watertight integrity.
4.2 Storage
Store the drone and its accessories in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided carrying case for protection during transport and storage.
5. Troubleshooting
This section addresses common issues you might encounter with your Gladius Mini.
5.1 Connection Issues
- No Wi-Fi Connection: Ensure the base station is powered on and your mobile device is connected to its Wi-Fi network. Try restarting both the base station and your mobile device.
- Frequent Disconnections: Operate the drone within the recommended range of the base station. Minimize interference from other wireless devices. Ensure the mobile app is up-to-date.
5.2 Motor or Movement Problems
- Motors Seized/Not Responding: This can occur if sand or debris enters the motor mechanisms. Immediately retrieve the drone, rinse the motors thoroughly with fresh water, and gently try to free them by hand. If the issue persists, contact customer support.
- Unstable Operation: Ensure the drone's thrusters are free from obstructions. Perform a calibration if available in the app.
5.3 App Functionality
- App Crashes/Unresponsive: Ensure your mobile device's operating system and the CHASING app are updated to the latest versions. Close other background applications.
- Live Streaming Issues: Live streaming requires a stable internet connection on your mobile device, separate from the drone's Wi-Fi. Verify your device's cellular data or external Wi-Fi connection.
