Calibrating Front Sensors
Obstacles Sensing cameras that installed on landing gear are calibrated on delivery. However these
camera are vulnerable to excessive impact, hence it will require calibration via DJI Assistant 2 from time
to time. Follow the steps below to calibrate the camera when the DJI GO app prompt you to do so.
Detection Range
The detection range of the Obstacle Sensing and Vision Positioning System is depicted as follow. Note
that the aircraft cannot sense and avoid the obstacles that are not within the detection range.
Using Vision Positioning
Vision Positioning is activated automatically when the aircraft is turned on. No further action is
required. Vision Positioning is typically used in indoor environments, where GPS is unavailable.
Using the sensors that are built into the Vision Positioning system, the aircraft can hover precisely
even without GPS.

Phantom 4 User Manual
Follow the steps below to use Vision Positioning:
1. Toggle the ight mode switch to P-mode.
2. Place the aircraft on a at surface. Note that the Vision Positioning system cannot
work properly on surfaces without clear pattern variations.
3. Turn on the aircraft. The aircraft status indicator will ash green two times, which
indicates the Vision Positioning system is ready. Gently push the throttle up to lift
off and the aircraft will hover in place.
ON OFF
Auto Hold
The performance of your Vision Positioning System is affected by the surface over which it is
ying. The ultrasonic sensors may not be able to accurately measure distances when operating
above sound-absorbing materials. In addition, the camera may not function correctly in
suboptimal environments. The aircraft will switch from P-mode to A-mode automatically if neither
GPS nor Vision Positioning System are available. Operate the aircraft with great caution in the
following situations:
Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).
Flying over a highly reective surfaces.
Flying at high speeds(over 10 m/s at 2 meters or over 5 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 the same design).
Flying over inclined surfaces that will deect sound waves away from the aircraft.
Assisted Breaking from Obstacle Sensing System
Powered by the Obstacle Sensing System, the aircraft will now be able to actively initiate breaks when
obstacles are detected direct ahead of the aircraft. Note that Obstacle System works best when light
condition is ideal and the obstacle does not have feature-less pattern. In addition, the aircraft speed
cannot exceed over 8 meter/second so that the aircraft can break and stop at the safe distance.

Flight Recorder
Flight data is automatically recorded to the internal storage of the aircraft. This includes flight
telemetry, aircraft status information, and other parameters. To access these data, connect the
aircraft to the PC through the Micro USB port and launch the DJI GO app.
Attaching and Detaching the Propellers
Use only DJI approved propellers with your Phantom 4. The grey and black ring on the propeller
indicate where they should be attached and in which direction whey should spin.
Propellers Silver Ring Black Ring
Figure
Attach On Motors without three dots Motors with three dots
Legends Lock : Turn the propellers in the indicated direction to mount and tighten.
Unlock : Turn the propellers in the indicated direction to loosen and remove.
Keep the sensors clean at all times. Dirt or other debris may adversely affect the effectiveness
of the sensors.
Vision Positioning is only effective when the aircraft is at altitudes of 0.3 to 10 meters.
The Vision Positioning System may not function properly when the aircraft is ying over water.
The 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.
Keep the animals away from the aircraft when Vision Positioning system is activated. The sonar
sensor emits high frequency sounds that are only audible to some animals.
Attaching the Propellers
1. Be sure to remove the warning stickers from the motors before attaching the propellers.
2. Mount the propellers with black propeller rings to the motors with black dots. Mount the propellers with
sliver propeller rings to the motors without black dots. Press t he propeller down onto the mounting
plate and rotate in the lock direction until it is secured in its position.

DJI Intelligent Flight Battery Functions
1. Battery Level Display: The LED indicators display the current battery level.
2. Battery Life Display: The LEDs display the current battery power cycle.
3. Auto-Discharging Function: To prevent swelling, the battery automatically discharges to below 65% of
total power when it is idle for more than ten days. It takes around two days to discharge the battery to
65%. It is normal to feel moderate heat being emitted from the battery during the discharge process.
Discharge thresholds can be set in the DJI GO app.
4. Balanced Charging: Automatically balances the voltage of each battery cell when charging.
5. Overcharge Protection: Charging automatically stops when the battery is fully charged.
6. Temperature Detection: The battery will only charge when the temperature is between 5°C (41°F) and
40°C (104°F).
The Intelligent Flight Battery must be fully charged before using it for the first time. Refer to
“Charging the Intelligent Flight Battery” for more information.
Be aware that the output power of the supplied Phantom 4 charger is 100W.
DJI Intelligent Flight Battery
The DJI Intelligent Flight Battery has a capacity of 5350 mAh, a voltage of 15.2 V, and a smart charge/
discharge functionality. It should only be charged using an appropriate charger that has been approved
by DJI.
Intelligent Flight Battery Charger
Be aware of the sharp edges of the propellers. Handle with care.
Use only the DJI approved propellers. Do not intermix the propellers types.
Stand clear of the motors and DO NOT touch the propellers when they are spinning.
Detaching the Propellers
Press down the propellers onto the motor mount, rotate the propeller according to the marked direction to
unlock the propeller.
Check that the propellers and motors are installed correctly and rmly before every ight.
Ensure that all propellers are in good condition before each ight. DO NOT use aged, chipped,
or broken propellers.
To avoid injury, STAND CLEAR of and DO NOT touch propellers or motors when they are spinning.
ONLY use original DJI propellers for a better and safer ight experience.

2. It is not recommended that the battery be used in extremely low temperature (< -10°C) environments.
Battery voltage should reach the appropriate level when operating environment with temperatures
between -10°C and 5°C.
3. End the ight as soon as the DJI GO app displays the “Low Battery Level Warning” in low temperature
environments.
4. Keep the battery indoors to warm it before ying in low temperature environments.
5. To ensure optimal performance of the battery, keep the battery temperature above 20°C.
6. The charger will stop charging the battery if the battery cell’s temperature is not within the operating
range (0°C ~ 40°C ).
In cold environments, insert the battery into the battery compartment and allow the aircraft for
approximately 1-2 minutes to warm up before taking off.
