1. Charging

Charging the Batteries

a. Connect the battery station to a power outlet using the AC power adaptor cable.

b. Press the power button once to power on the battery station.

c. Insert the batteries into the battery ports to start charging.

Charging the DJI RC Pro

Connect the battery station and the remote controller USB-C ports using a USB-C to USB-C cable to activate and charge the internal battery.

2. Preparing the Remote Controller

Check battery level: Press the power button once.

Power on/off: Press and then press and hold for two seconds. The remote controller needs to be activated before using for the first time. Follow the prompts to activate.

Adjusting the Antennas

Lift and adjust the antennas. The strength of the remote controller signal is affected by the position of the antennas.

Diagrams show how to adjust the remote controller antennas for optimal signal strength, indicating different angles relative to the controller.

3. Preparing the Aircraft

Installing the Landing Gears

Install the landing gears, slide the gear lock to the end of the landing gear, then rotate it about 90° until the dot is in sync with the alignment mark.

A diagram illustrates the installation of landing gear, showing a gear lock and an alignment mark for proper positioning.

Unfolding the Aircraft

Unfold the frame arms on both sides in the same way. Lock the frame arms and unfold the propellers.

Illustrations show the process of unfolding the aircraft's frame arms and propellers.

Mounting the Gimbal and Camera

Mount the gimbal and camera according to the specific instructions for your configuration.

Mounting the Intelligent Flight Batteries

Check battery level: Press the battery level button once.

Power on/off: Press and then press and hold for two seconds.

4. Flight

Manual Takeoff / Landing

Use the Combination Stick Command (CSC) to start or stop the motors.

Takeoff: Slowly push the left stick up. ⬆️

Landing: Slowly push the left stick down until the aircraft lands. Hold for a few seconds to stop the motors. ⬇️

The default flight control mode is Mode 2. In Mode 2:

• The left stick controls the aircraft's altitude (up/down) and heading (yaw left/right).
• The right stick controls the aircraft's forward, backward, and lateral (left/right) movements.

Diagrams detail the control stick functions in Mode 2. Left stick: Up controls ascent, Down controls descent, Left controls yaw left, Right controls yaw right. Right stick: Up controls forward flight, Down controls backward flight, Left controls lateral left movement, Right controls lateral right movement.
