Before every flight with your DJI MINI 4 PRO, ensure you complete the following checklist:

1. Make sure the propeller holder and the gimbal protector are removed.

2. Make sure the Intelligent Flight Battery and the propellers are mounted securely.

3. Make sure the remote controller, mobile device, and Intelligent Flight Battery are fully charged.

4. Make sure the aircraft arms are unfolded.

5. Make sure the gimbal and camera are functioning normally.

6. Make sure that there is nothing obstructing the motors and that they are functioning normally.

7. Make sure that DJI Fly is successfully connected to the aircraft.

8. Make sure all camera lenses and sensors are clean.

9. Only use genuine DJI parts or DJI authorized parts.

10. Make sure the Obstacle Avoidance Action is set in DJI Fly, and the max flight altitude, max flight distance and RTH altitude are all set properly according to the local laws and regulations.

Auto Takeoff:

1. Launch the DJI Fly app and enter the camera view.

2. Complete all steps in the pre-flight checklist.

3. Tap the takeoff icon. If conditions are safe, press and hold the button to confirm.

4. The aircraft will take off and hover approximately 1.2 m (3.9 ft) above the ground.

Auto Landing:

1. Tap the landing icon. If conditions are safe, press and hold the button to confirm.

2. Auto landing can be canceled by tapping the cancel icon.

3. If the Downward Vision System is working normally, Landing Protection will be enabled.

4. The motors will stop automatically after the aircraft has landed.

Starting the Motors:

Perform the Combination Stick Command (CSC) to start the motors. Pull both control sticks to the bottom inner or outer corners simultaneously. Once the motors start spinning, release both sticks.

Stopping the Motors on the Ground:

There are two methods to stop the motors after the aircraft has landed:

• Method 1: Push the throttle stick (left stick in Mode 2) down and hold it until the motors stop.

• Method 2: Perform the same CSC used to start the motors until they stop.

Stopping the Motors Mid-Flight (Emergency):

Stopping the motors mid-flight will cause the aircraft to crash. This should only be done in an emergency. The default setting is “Emergency Only,” which allows motor stop mid-flight only if a collision, stalled motor, or out-of-control situation is detected. To stop the motors mid-flight, perform the same CSC used to start them and hold for two seconds. This setting can be changed to “Anytime” in the app, but use this option with extreme caution.

The DJI MINI 4 PRO is controlled using the two control sticks on the remote controller. The default control mode is Mode 2. Here are the controls for the different modes:

Mode 1:

• Left Stick: Moves the aircraft forward/backward and left/right.

• Right Stick: Ascends/descends and rotates (yaws) the aircraft left/right.

Mode 2 (Default):

• Left Stick: Ascends/descends (throttle) and rotates (yaws) the aircraft left/right.

• Right Stick: Moves the aircraft forward/backward (pitch) and left/right (roll).

Mode 3:

• Left Stick: Moves the aircraft forward/backward and rotates (yaws) left/right.

• Right Stick: Ascends/descends and moves the aircraft left/right.

Follow this procedure for manual takeoff and landing:

1. Place the aircraft in an open, flat area with the rear facing you.

2. Power on the remote controller and the aircraft.

3. Launch DJI Fly and enter the camera view.

4. In Settings > Safety, set the Obstacle Avoidance Action to Bypass or Brake and set an appropriate Max Altitude and RTH Altitude.

5. Wait for the aircraft self-diagnostics to complete. If no warnings appear, start the motors.

6. Push the throttle stick (left stick in Mode 2) up slowly to take off.

7. To land, hover over a level surface and push the throttle stick down to descend.

8. After landing, push the throttle down and hold it until the motors stop.

9. Power off the aircraft before powering off the remote controller.

SmartShots on the DJI MINI 4 PRO are intelligent flight modes that help you capture cinematic shots. They include Spotlight, Point of Interest (POI), and ActiveShots. The aircraft does not automatically take photos or record videos in these modes; you must manually start and stop recording.

1. Launch the aircraft and take off.

2. Drag-select the subject in the camera view, or enable Subject Scanning in Control settings and tap the recognized subject to enable SmartShots.

a. Spotlight (Default): The aircraft enters Spotlight mode by default. Manually control the aircraft’s flight with the control sticks while the camera stays locked on the subject. Tap the record button to start shooting.

b. Point of Interest: Tap on the bottom of the screen to switch to POI. Set the flight direction and speed, then tap GO. The aircraft will automatically circle the subject. You can still use the control sticks for manual adjustments.

c. ActiveShots: Tap to switch to ActiveShots. Select a sub-mode (Auto, Manual, Parallel) and tap GO. The aircraft will start tracking the subject automatically. In Manual mode, a trace wheel appears, allowing you to select the tracking direction.

MasterShots keeps a subject at the center of the frame while the DJI MINI 4 PRO executes different maneuvers in sequence to generate a short cinematic video automatically.

Using MasterShots:

1. Launch the aircraft and make it hover at least 2 m (6.6 ft) above the ground.

2. In DJI Fly, tap the shooting mode icon to select MasterShots and read the instructions. Ensure there are no obstacles in the surrounding area.

3. Drag-select the subject in the camera view and set the flight range. Check the map view for the estimated flight path to ensure it is clear of obstacles like high buildings.

4. Tap Start. The aircraft will begin flying and recording automatically. It will return to its original position when finished.

5. After completion, you can tap the playback icon to access, edit, or share the video.

To exit MasterShots, press the Flight Pause button on the remote controller or tap the Stop icon in DJI Fly. The aircraft will brake and hover.

The DJI MINI 4 PRO offers several QuickShots modes where the aircraft records a short video while performing a preset flight maneuver:

• Dronie: The aircraft flies backward and ascends with the camera locked on the subject.

• Rocket: The aircraft ascends with the camera pointing downward.

• Circle: The aircraft circles around the subject.

• Helix: The aircraft ascends and spirals around the subject.

• Boomerang: The aircraft flies around the subject in an oval path, ascending as it flies away and descending as it returns.

• Asteroid: The aircraft flies backward and upward, takes several photos, then flies back to the start. The generated video starts with a panorama from the highest point and then shows the view as it descends.

The DJI MINI 4 PRO supports three flight modes, which can be selected using the Flight Mode switch on the remote controller:

• Normal Mode: The aircraft utilizes GNSS, the omnidirectional vision system, the downward vision system, and the 3D infrared sensing system to locate and stabilize itself. Maximum horizontal speed is 12 m/s.

• Sport Mode: The aircraft’s responses are optimized for agility and speed. Obstacle sensing is disabled in this mode. Maximum horizontal speed is 16 m/s. Use with caution as braking distance is significantly increased.

• Cine Mode: Based on Normal mode but with a limited flight speed, making the aircraft more stable for shooting smoother footage.

If vision systems are unavailable and the GNSS signal is weak, the aircraft will automatically switch to Attitude (ATTI) mode, where it is more susceptible to environmental factors like wind and cannot hover or brake automatically.

When the DJI MINI 4 PRO is powered on but the motors are not running, the status indicators show the flight control system’s status.

Normal States:

Warning States:

After the motors start, the indicators will blink green.

The Return to Home (RTH) function brings the DJI MINI 4 PRO back to the last recorded Home Point. It can be triggered in three ways: user-initiated (Smart RTH), low battery (Low Battery RTH), or loss of remote controller signal (Failsafe RTH).

When Advanced RTH is triggered, the aircraft automatically plans the best RTH path, which is displayed in DJI Fly. The aircraft will fly back and land at the Home Point. The Home Point is typically the location where the aircraft last received a strong GNSS signal before or during takeoff. You can manually update the Home Point during flight via the DJI Fly app.

You can choose between two RTH settings in the DJI Fly safety settings:

1. Optimal: If lighting and the environment are suitable for the vision systems, the aircraft will automatically plan the most efficient RTH path to save battery and time. It will adjust its altitude to bypass obstacles regardless of the preset RTH Altitude. If conditions are not suitable for vision systems, it will revert to Preset RTH.

2. Preset: The aircraft will ascend to a pre-set RTH altitude if its current altitude is lower, and then fly in a straight line to the Home Point. The aircraft will not avoid obstacles if the vision systems are unavailable. If the current altitude is higher than the RTH altitude, it will return at its current altitude. The following table describes its behavior based on distance from the home point:

The DJI MINI 4 PRO is equipped with an omnidirectional vision system (forward, backward, lateral, upward), a downward vision system, and a 3D infrared sensing system. These systems allow for positioning and omnidirectional obstacle sensing.

• The omnidirectional vision system uses four cameras at the front of the aircraft.

• The downward vision system uses two cameras at the bottom.

• The 3D infrared sensing system on the bottom helps assess distance to obstacles and the ground.

These systems work best in environments with adequate lighting and clearly marked or textured obstacles. They are automatically enabled in Normal or Cine mode when Obstacle Avoidance is set to Bypass or Brake in DJI Fly.

Detection Ranges:

There are two types of propellers, marked and unmarked, which are designed to spin in different directions. You must match the propellers to the correct motors.

Attaching the Propellers:

1. Attach the marked propellers to the motors on the marked aircraft arms.

2. Attach the unmarked propellers to the motors on the unmarked arms.

3. Use the screwdriver provided in the aircraft package to mount the propellers. Ensure the screws are secure.

Detaching the Propellers:

Use the provided screwdriver to loosen the screws and detach the propellers from the motors.

Important Notes:

• Propeller blades are sharp; handle with care.

• Only use the provided screwdriver to avoid damaging the screws.

• If a propeller is broken, remove and discard both propellers and screws from that motor. Replace them with a new pair from the same package.

• Ensure propellers are in good condition before each flight. Do not use aged, chipped, or broken propellers.

Press the power button on the Intelligent Flight Battery once to check the current battery level. The four battery level LEDs will indicate the charge status.

You can charge the battery either while it is mounted in the aircraft or by using the DJI Mini 3 Pro Two-Way Charging Hub.

Using a Charger with the Aircraft:

1. Ensure the battery is correctly installed in the aircraft.

2. Connect a charger to an AC power supply (100-240 V, 50/60 Hz).

3. Connect the charger to the USB-C charging port on the aircraft.

4. The battery level LEDs will display the charging progress.

5. The battery is fully charged when all LEDs are solid. Detach the charger.

Using the Charging Hub:

1. Insert up to three batteries into the charging hub.

2. Connect the hub to a power outlet using a USB-C cable and a compatible charger (e.g., DJI 30W USB-C charger).

3. The hub charges batteries sequentially, starting with the one with the highest power level. The status LEDs for each port will indicate the charging status.

Do not charge a battery immediately after flight as it may be too hot. Wait for it to cool down.

Inserting the Battery:

Insert the Intelligent Flight Battery into the battery compartment of the aircraft. Push it in until you hear a clicking sound, which indicates the battery buckles are securely fastened.

Removing the Battery:

Press the textured part of the battery buckles on both sides of the battery to release it, then pull it out from the compartment.

Important: Do not insert or remove the battery while the aircraft is powered on. Ensure the battery is securely mounted before flight.

The DJI MINI 4 PRO has two gimbal operation modes, which can be switched in Settings > Control in the DJI Fly app:

• Follow Mode: The angle of the gimbal remains stable relative to the horizontal plane. This mode is suitable for shooting stills and standard video where you want a level horizon.

• FPV Mode: The gimbal synchronizes with the movement of the aircraft, tilting and rolling with the drone to provide a first-person flying experience.

There are several ways to export photos and videos from your DJI MINI 4 PRO:

• QuickTransfer: Connect the aircraft directly to your mobile device via Wi-Fi to download files through the DJI Fly app at a high speed without using the remote controller.

• Connect to a Computer: Use a data cable to connect the aircraft to a computer. You can then export footage from the internal storage or the mounted microSD card. The aircraft does not need to be powered on for this process.

• Use a Card Reader: Power off the aircraft, remove the microSD card, and insert it into a card reader connected to your computer to export the files.

Here are solutions for common issues:

• Why can the battery not be used before the first flight?
The battery must be activated by charging it for the first time.
