5.4 Pairing and Calibration

1. Place the drone on a flat, level surface.
2. Turn on the drone, then turn on the remote control.
3. The drone and remote control will automatically pair. Wait for the indicator lights to stabilize.
4. Perform gyroscope calibration by pushing both control sticks to the bottom-left or bottom-right corners simultaneously until the drone lights flash and then become solid.
5. Perform GPS calibration (if applicable) by following the on-screen instructions on the remote control or app. This usually involves rotating the drone horizontally and vertically.

6. Operating Instructions

6.1 Pre-Flight Checks

• Ensure batteries are fully charged in both drone and remote control.
• Check propellers for damage and ensure they are securely attached.
• Confirm drone and remote control are paired and calibrated.
• Ensure you are in a safe, open flying area.

6.2 Takeoff and Landing

• Automatic Takeoff: Press the one-key takeoff button on the remote control. The drone will ascend to a safe altitude and hover.
• Manual Takeoff: Push both control sticks to the bottom-inner corners to start the motors, then slowly push the throttle stick up to ascend.
• Automatic Landing: Press the one-key landing button. The drone will descend and land automatically.
• Manual Landing: Slowly pull the throttle stick down until the drone lands, then push both sticks to the bottom-inner corners to stop the motors.

6.3 Flight Controls (Mode 1)

• Left Stick (Throttle): Up/Down for altitude, Left/Right for yaw (rotation).
• Right Stick (Direction): Up/Down for forward/backward, Left/Right for left/right strafing.

6.4 Special Features

Image 6.1: GPS optical flow positioning ensures stable and safe flight with various return functions.

• GPS Return to Home (RTH): The drone will automatically return to its takeoff point if GPS signal is lost, battery is low, or the RTH button is pressed.
• 360° Obstacle Avoidance: The drone is equipped with sensors to detect and avoid obstacles in its path, enhancing flight safety.
• Follow Me Mode: When activated via the app, the drone will automatically follow the remote control or connected smart device.
