Low Temperature Notice 1. Using the Intelligent Flight Battery at core temperatures below -10C (14F) is not advised. Between -10C

(14F) and 5C (41F), the Intelligent Flight Battery should attain a voltage of 4.2 V, but it is recommended applying the insulation sticker to the battery to avoid a rapid drop in temperature. 2. In cold environments (i.e. air temperature below 5C (41F)), the performance of the Intelligent Flight Battery is reduced. Ensure the Intelligent Flight Battery is fully charged and attains a voltage of 4.35 V before takeoff. 3. In very cold environments (e.g. air temperature of -20C (-4F), battery core temperature of 5C (41F)), the Intelligent Flight Batterys core temperature will drop rapidly even after pre-heating, and its performance is significantly reduced. It is not recommended to fly under such conditions. 4. If the DJI GO app displays the Low Battery Level warning, stop flying and land the aircraft immediately. You will still be able to control the aircrafts movement when this warning is triggered. 5. To ensure the optimal performance, maintain the Intelligent Flight Batterys core temperature above 20C

(68F) in use. Ensure the temperature of the Intelligent Flight Battery exceeds 5C (41F) before takeoff. To warm up the battery, power on the Intelligent Flight Battery inside the battery compartment for approximately 1-2 minutes before takeoff. Begin flying by hovering the aircraft at a low altitude (for approximately 1 minutes) to ensure an appropriate battery temperature is reached. 10 Checking the Battery Level The Battery Level Indicators display how much remaining charge the battery has. When the battery is powered off, press the Power Button once. The Battery Level Indicators will light up to display the current battery level. The Battery Level Indicators will also show the current battery level during charging and discharging. The indicators are defined below. The LED is on. The LED is flashing. The LED is off.

Remote Controller Compliance Version The WIND-4s remote controller meets FCC and CE regulations. 23 Return-to-Home and Dynamic Home Point Return-to-Home Return-to-Home (RTH) refers to the process in which the aircraft automatically returns to the last recorded Home Point. WIND-4 comes with three RTH modes: Smart RTH, Low Battery RTH and Failsafe RTH. GPS Description When the GPS signal is strong (i.e. the green GPS icon is followed by at least two green bars

) during takeoff, the location where the aircraft takes off will be recorded as the Home Point. The Aircraft Status Indicator will flash quickly when the Home Point has been recorded. You can update the Home Point via the DJI GO app. Home Point Smart RTH To initiate Smart RTH, use the RTH button on the remote controller or tap the RTH icon in the DJI GO app and follow the on-screen instructions when GPS is available. The aircraft then will automatically return to the last recorded Home Point. Use the remote controller to control the aircrafts orientation to avoid obstacles. Press and hold the Smart RTH button once to start Smart RTH, and press the Smart RTH button again to terminate Smart RTH and regain full control of the aircraft. Low Battery RTH Low Battery RTH will be triggered when the DJI Intelligent Flight Batterys charge drops to a point that may affect the safe return of the aircraft. You are advised to fly your aircraft to the Home Point or land it immediately when prompted to do so. A warning will be shown in the DJI GO app when a low battery warning is triggered. The aircraft will automatically return to the Home Point if no action is taken after a ten-second countdown. You can cancel the RTH procedure by pressing the RTH button on the remote controller. The thresholds for these warnings are automatically determined based on the aircrafts current height and distance from the Home Point. The aircraft will land automatically if the current battery charge can only allow the aircraft to descend from its current height. You can still use the remote controller to alter the aircrafts orientation during landing. The Battery Level Indicator that will be displayed in the DJI GO app is shown below:

24 Battery Aircraft Level Description Status Warning Indicator DJI GO App Flight Instruction Tap Go-home to have the aircraft return to the Home Point and land automatically, or Cancel to resume Low Battery Level Warning The remaining charge is only Flashing red slowly normal flight. If no Fly the aircraft to the Home Point and action is taken, the land it as soon as possible, then stop sufficient for RTH. aircraft will the motors and replace the battery. automatically return to the Home Point and land after 10 seconds. The remote controller will sound an alarm. The Aircraft Status Indicator will flash red and the aircraft will start to descend. The remote controller will sound an alarm. Critically Low Battery Level Warning The remaining charge is only sufficient for landing from the current height. Flashing red quickly Allow the aircraft to descend and land automatically. 25 When Critically Low Battery Level Warning is triggered and the aircraft begins to land automatically, you can push the left stick upward to make the aircraft hover at its current altitude and then navigate it to a location that is suitable for landing. The colored zones and markers on the Battery Level Indicator bar show the estimated remaining flight time. They will change according to the aircrafts height and distance from the Home Point. Failsafe RTH Failsafe RTH is activated automatically if the remote controller signal is lost for more than three seconds, provided that the GPS signal is strong (the GPS icon is green), the compass is working normally and the Home Point has been recorded successfully. You can interrupt the Failsafe RTH and regain control of the aircraft if the remote controller signal is recovered. The aircraft descends and lands automatically if Failsafe RTH is triggered when the aircraft is flying within a 20 meter (65 foot) radius of the Home Point. The aircraft cannot return to the Home Point when GPS signal is weak or unavailable. During Failsafe RTH, the aircraft cannot avoid obstacles. Before flight, please set the Failsafe RTH height higher than any obstacles in the flight area under Advanced Settings in the DJI GO app. Launch DJI GO, enter the Camera screen and select Mode > Advanced Settings > Failsafe Mode to set the Failsafe altitude. The aircraft will stop ascending and return to the Home Point if you move the throttle stick during Failsafe RTH. Dynamic Home Point Dynamic Home Point can be used when you are moving while flying the WIND-4, such as in a car or on a boat. When Dynamic Home Point is enabled, the aircrafts Home Point will be updated in real time and the remote controllers GPS location will be recorded as the latest Home Point. Locations listed below can be set as a Dynamic Home Point:

26 1. Set the aircrafts current coordinates as the new Home Point. 2. Set the remote controllers coordinates as the new Home Point When setting a Home Point with the built-in GPS module in the remote controller, ensure that there is no obstacle over the GPS or tall building around. Perform the following steps to enable Dynamic Home Point:

1. Connect the remote controller to the mobile device, launch the DJI GO app and enter the Camera screen. 2. Tap and select

. In this case, the remote controllers coordinates will be recorded as the aircrafts latest Home Point. 3. Tap and select

. In this case, the aircrafts coordinates will be recorded as the latest Home Point. 4. After the Home Point has been set successfully, the Aircraft Status Indicator will flash green quickly. 27 Flight Operation Environment Requirements 1. DO NOT use the aircraft in severe weather conditions, including wind speeds exceeding 10 m/s, snow, rain and fog, etc. 2. Only fly in open areas. Tall structures and large metal structures may affect the accuracy of the on-board compass and GPS system. 3. Avoid obstacles, crowds and animals, etc. 4. Minimize interference by avoiding areas with high levels of electromagnetism, including base stations and radio transmission towers, etc. Ensure that GPS signal is strong during operation. The compass and GPS will not work in Polar Regions of earth and the aircraft will switch to A-mode 5. 6. automatically. Flight Limits and No Fly Zones All unmanned aerial vehicle (UAV) operators should abide by all regulations set forth by government and regulatory agencies including the ICAO and FAA. For safety reasons, flights are limited by default, which helps you operate this product safely and legally. Flight limitations include height limits, distance limits and No Fly Zones. When operating in P-mode, height limits, distance limits and No Fly Zones function concurrently to manage flight safety. In A-mode, only height limits are in effect, which by default prevents the aircraft altitude from exceeding 120 meters. 28 Maximum Height and Radius Limits The maximum height and radius limits can be changed in the DJI GO app. Once set, your WIND-4 will fly in a restricted cylinder that is determined by these settings. The tables below show the details of these limits. Safe to Fly (Strong GPS Signal) Flashing Green Flight Limit DJI GO App Aircraft Status Indicator Max. Aircrafts height cannot exceed the Warning: Height limit Height specified value. reached. Max. Flight distance must be within the Warning: Distance limit Radius max radius. reached. None Flashing red rapidly when close to the max radius Safe to Fly (No GPS Signal) Flashing Yellow Flight Limit DJI GO App Aircraft Status Indicator Max. Height When the max. height set in the DJI GO app is less than or equal to 500 meters (1640 feet), the aircrafts height cannot exceed the max. height set in the DJI GO app. When the max. height set in the DJI GO app is more than 500 meters (1640 feet), the aircrafts height cannot exceed 500 meters (1640 feet). Warning: Height limit reached. None 29 Max. Radius No limit If the aircraft flies out of the limit, you can still control the aircraft via the remote controller, but cannot fly it any further. If the aircraft flies out of the maximum radius, it will fly back within the maximum radius automatically when the GPS signal is strong. 30 No Fly Zones No Fly Zones are divided into Airports and Restricted Areas. All No Fly Zones are listed on the DJI official website at http://www.dji.com/flysafe/no-fly. Airport (With GPS)

[1] Airport No Fly Zones include No Fly Zones and Restricted Altitude Zones. Flight is prevented in No Fly Zones but is allowed with height restrictions in the Restricted Altitude Zones.

[2] R1 meters (the value of the R1 depends on the size and shape of the airport) around the airport is a No Fly Zone, inside of which takeoff is prohibited.

[3] From R1 meters to R1+1 meters around the airport the flight altitude is limited to a 15 degree inclination. Starting at 20 meters (65 feet) from the edge of airport and radiating outward. Flight altitude is limited to 500 meters (1640 feet) at R1+1 meters.

[4] When the aircraft comes within 320 feet (100 meters) of a No Fly Zone, a warning will be shown in the DJI GO app. 31 Restricted Areas (With GPS)

[1]

Restricted Areas do not have flight altitude restrictions.

[2]

R meters around the designated restriction area is a Take-off Restricted Area. Aircraft cannot take off within this zone. The value of R varies based on the definition of the restricted areas.

[3] A Warning Zone has been set around the Restricted Area. When the aircraft approaches within 100 meters (320 feet) of this zone, a warning will be shown in the DJI GO app. Semi-Automatic Descent: All stick commands are available except the throttle stick command during landing. Motors will stop automatically after landing. The Flight Mode Switch needs to be toggled to regain control of the aircraft. This is the same as regaining control during RTH. When flying in restricted-altitude flight zone and warning zone, the Aircraft Status Indicator will flash yellow quickly for three seconds, and then start indicating the current flight status for five seconds. DO NOT fly close to airports, highways, railway stations, railway lines, city centers or other busy areas to ensure safety. Try to fly the aircraft within visual range. 32 Preflight Checklist 1. 2. Ensure that the remote controller, Intelligent Flight Battery and mobile device are fully charged. Ensure that all components are intact. If a component is worn or damaged, please replace it with an intact one before flight. 3. Ensure that the propellers are intact and mounted firmly and correctly. The propellers should be unfolded fully. Calibrate the compass before flight. Check whether the motors work normally after power-on. Check whether the DJI DO app runs normally. 4. 5. 6. Flight Status Indicator The WIND-4 comes with front LEDs, rear LEDs and an Aircraft Status Indicator. The front LEDs and rear LEDs show the orientation of the aircraft. The Aircraft Status Indicator indicates the system status of the flight controller. The table below shows different indications of the Aircraft Status Indicator. Aircraft Status Indicator Description Flashing Red, Green and Yellow Power-on and self-check Alternatively Flashing Yellow Four Times Warming up Flashing Green Slowly Safe to fly (P mode with GPS) Flashing Yellow Slowly Safe to fly (Without GPS) Flashing Purple Twice Manual mode Flashing Green Quickly for 1.5 Seconds Home Point, Point of Interest, or Smart Course Angle set Warning successfully Flashing Yellow Quickly Remote controller signal lost Flashing Red Slowly Flashing Red Quickly Low battery level warning Critically low battery level warning Flashing Red Alternatively for 0.6 Seconds IMU error Solid Red Critical error Flashing Red and Yellow Alternatively Compass calibration required 33 Calibrating the Compass The compass must be calibrated before your first flight, otherwise, the aircraft may not work properly. The compass is a very sensitive instrument that requires regular calibration to ensure the optimal flight performance. Abnormal compass data due to a lack of calibration can lead to poor flight performance or even failure. Regular calibration enables the compass to keep the optimal performance. DO NOT calibrate the compass where there is a chance of strong magnetic interference, such as magnetite quarries, parking structures and underground steel reinforcements. DO NOT carry ferromagnetic objects, such as cellular phones, with you during calibration. DO NOT calibrate beside massive metal objects. DO NOT calibrate in an indoor space. Calibration Procedures Perform the following steps on an open area to calibrate the compass:

1. Launch the DJI GO app, enter the Camera screen, tap the Aircraft Status bar and Calibrate beside Compass. 2. When the Aircraft Status Indicator is solid yellow, the compass calibration initiates. 3. Hold the aircraft horizontally and rotate it 360 degrees. The Aircraft Status Indicators will be solid green. 4. Hold the aircraft vertically with its nose pointing downward and rotate it 360 degrees around the central axis. 5. When the Aircraft Status Indicator is flashing normally to show the current status of the aircraft, the compass calibration is successful. If the Aircraft Status Indicator is flashing red, the compass calibration failed. In this case, please recalibrate the compass from step 1. If the Aircraft Status Indicator is flashing red and yellow alternatively after the calibration completed, the compass has been interfered. In this case, recalibrate the compass in a place free of interference. 34 A prompt stating that compass calibration is required will pop up on the DJI GO app when the aircrafts compass needs to be calibrated before take-off. After the compass has been calibrated successfully, this prompt will disappear. 35 When to Recalibrate 1. The compass data is abnormal and the Aircraft Status Indicator is flashing yellow and green alternatively. 2. The aircraft is flying in a location that is far from your last flight. 3. The aircrafts mechanical structure has been changed. 4. Severe drifting occurs during flight. For example, the aircraft cannot fly in a straight line. Auto Takeoff and Auto Landing Auto Takeoff Auto takeoff can be used when the Aircraft Status Indicator is flashing green. Follow the steps below to use the auto takeoff feature:

1. Launch the DJI GO app and enter the Camera screen. 2. Ensure that the aircraft is in P-mode. 3. Conduct pre-flight check according to the on-screen instructions. 4. Tap and check whether the conditions are safe to fly. If yes, slide the icon to the right to confirm. 5. The aircraft will take off automatically and hover at 1.2 meters above ground. Auto-Landing Auto-landing can be used when the Aircraft Status Indicator is flashing green. Follow the steps below to use the auto-landing feature:

1. Ensure that the aircraft is in P-mode. 2. Tap and check whether the landing condition is ideal. If yes, tap Confirm. 3. The aircraft will land in place and then turn off. 36 Starting and Stopping the Motors Starting the Motors The Combination Stick Command (CSC) listed below is used to start and stop the motors. After the CSC has been conducted and the motors start, please release the sticks. Stopping the Motors There are two methods to stop the motors. 1. When the aircraft has landed, push the throttle stick down fully , then perform the CSC to stop the motors

. Release two sticks once the motors have stopped. 2. When the aircraft has landed, push the throttle stick down fully and hold. The motors will stop after three seconds. or Do not conduct the CSC when the aircraft is mid-flight. Otherwise, the aircraft will stop during flight and then crash. Flight Test 1. Place the aircraft on even ground with the Aircraft Status Indicator facing you. 2. Turn on the remote controller and Intelligent Flight Battery. 3. Launch the DJI GO app, connect the mobile device with WIND-4 and enter the Camera screen. 4. Wait until the Aircraft Status Indicator flashes green and SAFE TO FLY (GPS) is shown in the DJI GO app. Then perform CSC to start the motors. 5. Push the throttle stick up to take off. 6. To land, ensure the Operation Mode Switch is toggled to Manual Operation Mode, hover over a level surface and gently pull down on the throttle stick to descend slowly. 7. After landing, pull the throttle stick down fully for more than three seconds until the motors stop. 8. Power off the aircraft and then the remote controller. When the Aircraft Status Indicator flashes yellow quickly during flight, the aircraft has entered Failsafe RTH mode. When the Aircraft Status Indicator flashes red during flight, the critically low battery level warning has been triggered. In this case, please follow the instructions in the DJI GO app. Appendix Specifications Airframe 37 Diagonal Wheelbase Propulsion System Model Motors Stator Size KV Max. Thrust ESCs Max.
