The Autel EVO II Dual 640T V3 is a comprehensive solution for professionals in fields such as public safety (search & rescue, law enforcement, firefighting), industrial inspection (power lines, solar panels, buildings), construction,infrastructure monitoring, and environmental surveying, where high-quality thermal and visual data are critical.

Operating the Autel EVO II Dual 640T V3 requires adherence to specific procedures and best practices to ensure safe,efficient, and effective flights, especially given its advanced capabilities. Here are some special instructions and considerations:

1. Pre-Flight Checklist (Crucial for Every Flight):

• Battery Status: Ensure both the aircraft battery and the Smart Controller V3 are fully charged. A fully charged aircraft battery takes approximately 90 minutes, and the controller takes about 120 minutes.
• Gimbal Guard Removal: Always remove the gimbal cover before powering on the aircraft.
• Propellers:
  • Verify all propellers are undamaged and securely attached.
  • If reinstalling, ensure they are paired correctly to their respective motors using the white marks and rotated in the "lock" direction.
• Aircraft Arms: Ensure all four arms are fully unfolded and locked into place.
• Camera Lens & Sensors: Inspect and clean the camera lens and all obstacle avoidance sensors to ensure clear vision and proper functionality.
• SD Card: Ensure a compatible and formatted microSD card (up to 256GB, UHS-3 or Class 10 recommended) is inserted if you plan to record photos or videos.
• Controller Setup: Unfold the antenna and attach the control sticks to the Smart Controller V3. Ensure the antenna is angled correctly (180 or 260 degrees from the back of the controller, facing the aircraft) for optimal signal.
• App Status: Open the Autel Explorer App on the Smart Controller and check for any warnings or error messages. Address them before takeoff.
• Accessories: If using modular accessories (spotlight, loudspeaker, beacon), ensure they are securely mounted and functioning correctly.
• Flight Environment:
  • Local Regulations: Strictly abide by all local regulations regarding drone flight (e.g., flight zones, altitude limits, privacy laws).
  • Weather Conditions: Do NOT fly in adverse weather conditions like strong winds (exceeding 12 m/s), rain,hail, snow, fog, or extreme temperatures (outside -10°C to 40°C).
  • Interference: Avoid flying near strong electromagnetic interference sources (power lines, substations, radio towers, etc.) as they can affect GPS and transmission signals.
  • Obstacles: Choose an open, safe area free from physical obstacles (buildings, trees, etc.) that could block GPS signals or pose a collision risk.
• Line of Sight (LOS): Always keep the aircraft within your visual line of sight during flight.

2. Powering On and Off:

• Controller First: Press and hold the power button on the Smart Controller V3 for 2 seconds to turn it on.
• Aircraft Second: Press and hold the power button on the aircraft for 3 seconds to turn it on.
• Shutdown Sequence (Reverse Order): Power off the aircraft first by holding its power button, then power off the controller.

3. Flight Operations (Mode 2 Default):

• Motor Start: Hold both control sticks down and outwards (towards the bottom corners) for 2 seconds to start the motors.
• Takeoff: Slowly push the left command stick upward to take off.
• Landing & Shutdown: Gently lower the left stick to land. Once landed, hold both sticks down and outwards again to stop the motors.
• Low Battery Alarm: When a low battery alarm occurs, do not cancel the auto-return process. Allowing it to return ensures it has enough power to safely reach the home point.

4. Calibration Procedures:

• Compass Calibration:
  • The LED indicators on the rear arms will flash "RY – Alternate Flashing" if calibration is required.
  • Follow the on-screen prompts in the Autel Explorer app. Typically involves rotating the drone horizontally 360 degrees with the camera facing you, then rotating it 360 degrees again with the camera facing upwards.
  • If calibration fails, move to a different location and try again to avoid magnetic interference.
• Gimbal Calibration:
  • If the gimbal appears tilted, go into the Autel Explorer app settings, navigate to Gimbal, and select "Gimbal Auto Calibration." The gimbal will move through a calibration sequence.
• Obstacle Avoidance Sensor Calibration:
  • This usually requires a PC/Mac application called "Autel Vision Assistant Tool."
  • Connect the drone to your computer via USB-C, power it on, and run the calibration tool.
  • Follow the on-screen instructions, aiming the drone's sensors at the screen as indicated. Ensure your computer meets the recommended CPU performance.

5. Firmware and Software Updates:

• Importance: Regularly update both the drone's firmware and the Autel Explorer app to ensure optimal performance, unlock new features, and maintain regulatory compliance (especially for Remote ID in regions like the EU/UK).
• Process:
  • OTA (Over-the-Air): Connect your Smart Controller to Wi-Fi/cellular, power on the drone, and open the Autel Explorer app. It will usually prompt you if an update is available.
  • MicroSD Card: Download the firmware file from the Autel Robotics website, copy it to the root directory of a microSD card, insert it into the drone, and power on the drone and controller. Follow the on-screen prompts.
• Post-Update: After any update, it's highly recommended to perform a test flight in a safe, open area to verify all functions are operating normally.
• Autel IR Tool: Keep the separate Autel IR Tool software (for thermal image analysis) updated to benefit from the latest features and improvements.

6. Battery Safety and Storage:

• Charging:
  • Only use Autel Robotics provided batteries and chargers.
  • Do not charge damaged or bulging batteries.
  • Allow batteries to cool down to room temperature after flight before charging.
• Storage:
  • Store batteries in a dry, well-ventilated area at room temperature (ideally 22°C to 28°C).
  • Do not store near direct sunlight, sharp objects, water, metal, or reactive chemicals.
  • If storing for more than 6 days, discharge the battery to a storage charge level (around 50-60%) for optimal long-term health.
  • Keep batteries out of reach of children and pets.
• Disposal: Fully discharge batteries before disposal and dispose of them in a designated battery recycling bin.

7. Responsible Operation:

• Privacy: Be mindful of privacy concerns when operating the drone, especially with the high-resolution visual and thermal cameras.
• Safety Distance: Maintain a safe distance from people, animals, vehicles, and structures during takeoff, landing,and flight.
• Lost Connection: Familiarize yourself with the Return-to-Home (RTH) function and ensure your home point is accurately set before flight.
• Emergency Procedures: Understand how to initiate an emergency motor stop if necessary (though this should only be used in critical situations to prevent further damage or injury).
