                  Product Profile
                  Introduction
                  The Phantom 3 Professional is a brand new quadcopter capable of capturing HD video and transmitting
                  an HD video signal out of the box. The built-in camera has an integrated gimbal to maximize stability and
                  weight efficiency while minimizing space. Even when no GPS signal is available, Vision Positioning sys-
                  tem provides hovering precision.


                  Feature Highlights
Product Profile




                  Camera and Gimbal: The Phantom 3 Professional camera shoots, of course, 4K video and it is capable of
                  capturing 12 megapixel stills.

                  HD Video Downlink: Low latency, HD downlink powered by an enhanced version of the DJI Lightbridge
                  system.

                  DJI Intelligent Flight Battery: 4480 mAh DJI Intelligent Flight Battery employs new battery cells and a bat-
                  tery management system.

                  Flight Controller: The next generation flight controller system provides a more reliable flight experience. A
                  new flight recorder stores the flight data from each flight, and Vision Positioning enhances hovering preci-
                  sion when flying indoors and no GPS is available.

P mode (Positioning) : P mode works best when GPS signal is strong. There are three different states of P




                                                                                                                          Aircraft
mode, which will be automatically selected by the Phantom 3 Professional depending on signal strength
of GPS and Vision Positioning sensors :
    P-GPS: GPS and Vision Positioning both are available, and the aircraft is using GPS for positioning.
    P-OPTI: Vision Positioning is available but the GPS signal is not. Aircraft is using only Vision Position-
    ing for hovering
    P-ATTI: Neither GPS or Vision Positioning available, aircraft is using only its barometer for positioning,
    so only altitude is controlled.
A mode (Attitude): GPS and Vision Positioning System is not used for stabilization. The aircraft only uses its
barometer to stabilize. The aircraft can automatically return home if remote control signal is lost if the Home
Point is recorded successfully.
F mode (Function): Intelligent Orientation Control (IOC) is activated in this mode. For more information
about IOC, refer to the IOC section in the Appendix.

        Use the Flight Controller mode switch to change the flight mode of the aircraft, refer to the “Flight
        Mode Switch” on P24 for more information.


Flight Status Indicator
The Phantom 3 Professional comes with the Front LED and Aircraft Status Indicator. The positions of
these LEDs are shown in the figure below:

           Return to Home (RTH)
           The Return to Home (RTH) brings the aircraft back to the last recorded Home Point. There are three cases
           that will trigger RTH procedure; they are Smart RTH, Low Battery RTH and Failsafe RTH. The remaining
           part of this section will describe these three cases in details.

Low Battery RTH
The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to a point that
may affect the safe return of the aircraft. Users are advised to return home or land the aircraft immediately
when these warnings are prompted. DJI Pilot app will advise user to return the aircraft to the Home Point
when low battery warning is triggered. Aircraft will automatically return to the Home Point if no action is
taken after 10 seconds countdown. User can cancel the RTH by pressing once on the RTH button. The
thresholds for these warnings are automatically determined based on the current aircraft altitude and its
distance from the Home Point.
Aircraft will land automatically if the current battery level can only support the aircraft to land from the
current altitude. User can use the remote controller to control the aircraft’s orientation during the landing
process.

                    Aircraft cannot avoid obstruction during the Failsafe RTH, therefore it is important to set an
                    suitable Failsafe altitude before each flight. Launch the DJI Pilot app and enter “Camera” view
                    and select “MODE” to set the Failsafe altitude.
                    Aircraft will stop ascending and return to the Home Point immediately if throttle stick is moved
                    during the Failsafe RTH procedure


           Dynamic Home Point
           Dynamic home point is useful in situations when you are in motion and require a Home Point that is
           different from the takeoff point. You may only use the Dynamic Home Point feature on the GPS - enabled
           mobile device.




                     Ensure the space above the GPS module is not obstructed when using Dynamic Home Point.

Vision Positioning System
DJI Vision Positioning is a positioning system that uses ultrasonic and image data to help the aircraft
identify its current position. With the help of Vision Positioning, your Phantom 3 Professional can hover in
place more precisely and fly indoors or in other environments where there is no GPS signal available. The
main components of DJI Vision Positioning are located on the bottom of your Phantom 3 Professional,
including [1] one monocular camera and [2]two sonar sensors.




                                                                                 [1]

Using Vision Positioning
Vision Positioning is activated automatically when the Phantom 3 Professional is powered on. No manual
action is required. Vision Positioning is typically used in the indoor environment where no GPS is available.
By using the sensors on the Vision Positioning system, Phantom 3 Professional can perform precision
hovering even when no GPS is available.

              Positioning system is ready. Gently push the throttle up to lift off, and the aircraft will hover in place.


                   The performance of your Vision Positioning System is subject to the surface you are flying over.
                   The ultrasonic waves may not be able to accurately measure the distance over sound absorbing
                   materials, and the camera may not function correctly in suboptimal environments. The aircraft will
                   switch from “P” mode to “A” mode automatically if both GPS and Vision Positioning System are

                   not available. So operate the aircraft cautiously when in any of the following situations:
                    Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).
                    Flying over a highly reflective surfaces.
                    Flying at high speeds(over 8 m/s at 2 meters or over 4 m/s at 1 meter).
                    Flying over water or transparent surfaces.
                    Flying over moving surfaces or objects.
                    Flying in an area where the lighting changes frequently or drastically.
                    Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces.
                    Flying over surfaces that can absorb sound waves (e.g. thick carpet).
                    Flying over surfaces without clear patterns or texture.
                    Flying over surfaces with identical repeating patterns or textures (e.g. tiles with same design).
                    Flying over inclined surfaces that will deflect sound waves away from the aircraft.

                     Keep the sensors clean at all times. Dirt or other debris may adversely affect the effectiveness
                     of the sensors.
                     The effective hovering altitudes of the aircraft is from 0 to 3 meters.
                     Vision Positioning system may not function properly when the aircraft is flying over water.
                     Vision Positioning system may not be able to recognize pattern on the ground in low light
                     conditions (less than 100 lux).
                     Do not use other ultrasonic devices with frequency of 40 KHz when Vision Positioning system is
                     in operation.
                     Vision Positioning system may not be able to stabilize the aircraft when flying close to the
                     ground (below 0.5 meters) in fast speed.

                   Keep the animals away from the aircraft when Vision Positioning system is activated. The sonar
                   sensor emits high frequency sound that is only audible to some animals.
