4.2 Battery Installation and Charging

• Drone Battery: Insert the fully charged Lithium Polymer battery into the battery compartment on the drone's rear until it clicks into place.

• One Key Return: Initiates an automatic return to the take-off point (requires calibration).
• 3D Flip: Executes an acrobatic flip (ensure sufficient altitude).
• Fine-tuning Buttons: Used to trim the drone's flight to correct drift.

5.2 Pairing the Drone

1. Place the drone on a flat, level surface.
2. Power on the drone. The indicator lights will flash.
3. Power on the remote control.
4. Push the left joystick up to the maximum position, then pull it down to the minimum position. The drone lights will stop flashing and become solid, indicating successful pairing.
