switch to A-mode if P-mode or S-mode is unavailable. When flying
in A-mode, take EXTRA precautions because some features are
NOT available in A-mode.
1.
P-mode (Positioning):
P-mode works best when the GPS signal
is strong. The aircraft utilizes the GPS and Vision System to
automatically stabilize itself, navigate between obstacles or
track a moving object. Advanced features such as TapFly and
ActiveTrack are enabled in this mode.
2.
S-mode (Sports):
S-mode is identical to P-mode in terms of flight
controller settings, except that the handling gain values of the
aircraft are adjusted in order to enhance the maneuverability
of the aircraft. The maximum flight speed of the aircraft is
increased in this mode.
3.
A-mode (Attitude):
When neither the GPS nor the Vision System
is available, the aircraft will only use its barometer for positioning
to control the altitude.
If you intend to switch to modes that disable GPS assistance (e.g.,
Atti mode), you are required to accept the prompted disclaimer
to enable this function. If this function is enabled, you further
understand and agree that data including but not limited to function
records could be uploaded to and maintained on a DJI designated
server.
Failsafe and Return-to-Home
1. The Return-to-Home feature will NOT work if the GPS signal is
insufficient or if GPS is not active.
2. Press the RTH (Return-to-Home) Button on the remote controller
to bring the aircraft back to the Home Point. DO NOT resort to
turning off the remote controller to force the aircraft to return to
Home Point.
3. Tall buildings may adversely affect the Failsafe function. Please
adjust the aircraft location, altitude and speed while returning
home to avoid obstacles.
4. Make sure to always fly the aircraft within the transmission range
of the remote controller.
5. Only use the Failsafe and Return-to-Home functions in
emergency cases, as they may be affected by the weather, the
environment, or any nearby magnetic fields.
6. The aircraft cannot avoid obstacles during the Failsafe RTH
when lighting condition is not ideal, or if the Visual System
is otherwise disabled. Therefore, it is important to set an
appropriate Failsafe altitude before each flight.
7. When flying indoors, the aircraft cannot perform precision
hovering when flying above certain surfaces . Refer to the “Vision
System and Infrared Sensing System” section for complete
indoor flying criteria.
8. During the Failsafe RTH, the pilot may regain control of the
aircraft if the remote controller signal is re-established. Moving
the left stick when the aircraft reaches 20 meters (65 feet)
altitudes or beyond will cancel the ascending process and
command the aircraft to return to the home point immediately.
Pressing the RTH button once during the Failsafe RTH will
cancel the RTH process immediately.
9. If the battery life so allows, the aircraft may first return to the
last position where it had connection with the remote controller
during the Failsafe RTH. As a result, you may observe the
aircraft first flying away from you, then returning to the home
point.
Low Battery
1. When the Critical Battery Level Warning activates and the
aircraft is descending automatically, you may push the throttle
up to maintain the aircraft's altitude and navigate it to a more
appropriate location for landing.
2. When battery warnings are triggered, promptly bring the aircraft
back to the Home Point or land to avoid losing power during
flight and causing damage to the aircraft, property, animals, and
people.
Vision System and Infrared Sensing System*
1. The Vision System cannot work properly over surfaces that do
NOT have clear pattern variations. The Vision System is only
effective when the aircraft is at altitudes of 0.3 to 10 meters.
2. The Vision System may NOT function properly when the aircraft
is flying over water or snow-covered areas.
3. Keep your pets away from the aircraft when the Vision System
is activated, as the sonar sensors emit a high frequency sound
that is only audible to some pets.
4. Note that the Vision System may NOT function properly when
the aircraft is flying too fast or too low.
5. Operate the aircraft cautiously when in any of the following
situations:
a. Flying over monochrome surfaces (e.g., pure black, pure white,
pure red, pure green).
b. Flying over highly reflective surfaces;
c. Flying at high speeds (over 10m/s (32.8 feet/s) at 2 meters (6.6
feet) or over 5m/s (16.4 feet) at 1 meter (3.3 feet);
d. Flying over water or transparent surfaces;
e. Flying over moving surfaces or objects;
f. Flying in an area where the lighting changes frequently or
drastically;
g. Flying over extremely dark (< 10 lux) or bright (> 10,000 lux)
surfaces;
h. Flying over surfaces that can absorb sound waves (e.g., thick
carpet).
i. Flying over surfaces without clear patterns or texture;
j. Flying over surfaces with identical repeating patterns or textures
(e.g. tiles with same design);
k. Flying over inclined surfaces that will deflect sound waves away
from the aircraft.
l. Flying over obstacles with too small effective infrared reflective
surface.
6. Camera calibration is required if the aircraft suffers from
crashing. Calibrate the front cameras if the DJI GO 4 app
prompts you to do so.
7. Keep the sensors clean and at all times. DO NOT temper with
the sensors.
8. The Vision System may not be able to recognize pattern on the
ground in low light conditions (less than 100 lux).
9. Do not use other ultrasonic devices with frequency of 40 KHz
when Vision System is in operation.
10. Infrared Sensing System is enabled only in the Beginner mode
and Tripod Mode.
11. Binocular sensor contrary to the flight direction is enabled only
in the P-mode, Tapfly, and ActiveTrack mode when the aircraft
speed is less than 6m/s (13.4 mph).
12. The Vision System and Infrared Sensing System are not able to
brake and stop the aircraft at a safe distance from an obstacle if
the aircraft speed exceeds 14m/s (31.3 mph).
13. Please be mindful of blind spots of the Vision System and Infrared
Sensing System. The blind spots of Phantom 4 series differ,
please refer the illustrations below (Grey for blind spots)
* Rear Vision System and Infrared Sensing System are not applicable to Phantom 4,
Phantom 4 Advanced and Phantom 4 A.
