button on the back of the remote control to open the compartment cover Install
the smart battery into the battery compartment and push it up to the top Close
the cover Install 4G SIM Card Note: Follow the SIM card installation
direction, do not install it backwards Waiting for 30s after inserting the SIM
card, check the detection status of the 4G card, when it indicates the SIM has
been inserted, it means that the installation is correct, and then test
whether the network is unobstructed. Note: If 4G network is not available in
the area where you are located, you can use Huida small base station HD201
product as the network signal source of RTK service, or turn off RTK detection
of aircraft and use GPS to locate the flight.
Install RTK High-precision Positioning Module If RTK planning is used to plan
the working area, the RTK high-precision positioning module should be inserted
into the USB interface of the remote control
Check the Power Level
When returning to the homepage of Huida UAV APP, you can see the remaining
power of the built-in battery and the remaining power of the external battery.
Please ensure that the remote control is full of power before the flight
Deploy the remote control antenna and adjust the antenna position. Different
antenna positions will receive different signal strengths. When the antenna
and the back of the remote control are at an included angle of 80° or 180°,
and the antenna plane is facing the aircraft, the signal quality between the
remote control and the aircraft could be in the best state. When operating the
aircraft, ensure that the aircraft is in the best communication range. Adjust
the azimuth or distance between the operator and the aircraft in time to
ensure that the aircraft is always in the best communication range.
Attention: Do not use other communication equipment in the same frequency band
at the same time, in order not to interfere with the remote control signal.

Aircraft
Safe Parking Steps
During the operation of UAV, sometimes there are sudden special situations, so
it is necessary to use special operation procedures, and correct response can
ensure better operation results.
1.One-click return
If App prompts disconnection during operation, it can be returned by operating
remote control rocker at close distance, and can be automatically returned by
pressing the return button at long distance.
2.RTK detection
RTK positioning can achieve higher precision flight positioning, while high
precision RTK positioning data comes from Qianxun network. If you cannot
receive Qianxun data locally, enter the setting interface, turn off RTK
detection to carry out the operation
3.Duration after disconnection
After using the functions of returning and emergency landing, the spraying
system is abnormal and error is reported. At this point, the waypoint system
will automatically suspend the operation, record the disconnection point and
save in the ongoing module of land parcel management. After troubleshooting
the system, the task in progress can be called in the plot-in progress, and
the unfinished route operation can be directly executed after the call. The
function of duration after disconnection can avoid re-spraying and leakage,
and ensure the operation effect.
Startup and Shutdown
Startup: Press the button 1 shortly + press and hold it for 3-5s to turn on
the battery power of aircraft, and the aircraft is powered on at this time.
Shutdown: When the battery power of the aircraft is turned on, Press the
button 1 shortly + press and hold it for 3-5s to turn off the battery power,
and then the aircraft is powered off.
Charging of Flight Smart Battery Please use the charger provided by Huida to
charge the smart battery. Please use it after being fully charged for the
first time.
Please note: connect to the American plug for quick charging, and connect to
the national standard plug for mains charging. The maximum power is 8000W.
Please pay attention to the input power. If the power is insufficient, there
may be power safety risks. Please pay attention to the charging safety.
Flight Mode
The aircraft flies in P mode by default. If the attitude mode is allowed to be
turned on in the App, it can be switched by the flight mode physical key
switch of the remote control. P mode (positioning): RTK high-precision
positioning module is used to realize accurate hovering of aircraft. When GNSS
signal is better, GNSS can be used for accurate positioning; When RTK function
is turned on and differential data transmission is normal, centimeter-level
positioning can be obtained. When the GNSS signal is weak or the compass is
disturbed, it will passively enter the attitude mode. A mode (attitude): GNSS
module is not used for positioning, only attitude augmentation is provided.
The flight speed of aircraft in attitude mode is related to environmental
factors such as wind speed.
Attitude Mode Considerations In attitude mode, the aircraft is easily
disturbed by the outside world, resulting in drift in the horizontal
direction. Thus, in this mode, the aircraft cannot achieve fixed-point
hovering, and the user needs to manually control the remote control to achieve
aircraft hovering. In this mode, the control difficulty of the aircraft will
greatly increase. If you need to use this mode, you must be familiar with the
behavior of the aircraft in this mode and be able to control the aircraft
skillfully. When using, do not fly the aircraft out of a long distance, in
order to avoid the risk caused by losing the judgment of the attitude of the
aircraft because the distance is too long. Flying in the environment with poor
GNSS satellite signal and obstructions (such as near tall buildings) and
narrow space should be avoided as far as possible, in order to avoid passively
entering attitude mode and causing flight accidents.
Aircraft setup
Support in aircraft setting: departure/return altitude, departure/return
speed, hover or return after spraying the dosage (manual and manual
enhancement are not supported), continue operation after aircraft loss of
contact (hover, return, landing), continue operation after aircraft loss of
contact (only support full autonomous route mode), after operation completion
(return, hover), limit maximum flight altitude, limit maximum flight distance,
front light switch, rear light switch Bottom light switch, advanced setting
(IMU and compass), automatic fine adjustment switch of line
spacing (only effective when fully autonomous route)
Flight
Flight Environment 1.Do not spray in windy environment, and flight is not
allowed when the wind level is below grade 5. 2.Do not fly in bad weather,
such as foggy weather with low visibility, windy weather (wind speed is 8m/s
and above), rain and snow, etc. 3.Select an open place without tall buildings
around as the flight site. Tall buildings will block GNSS signals, which may
lead to RTK positioning failure of aircraft, and have great flight safety
risks.
4.Always fly within sight range and stay away from any obstacles, people,
water surface and animals. 5.No electromagnetic interference such as high-
voltage lines, communication base stations or transmission towers in and
around the operation area. 6.Do not fly above 4km above the sea level.
7.Ensure that GNSS signal is good and RTK antenna is not blocked during
flight. 8.Do not operate the UAV indoors.
Manual takeoff Execute one of the following joystick pushing actions to start
the motor, and then push the throttle lever up to take off.
Throttle lever (Left rocker for US operation mode)
Note: unlocking the motor for takeoff can only take effect in the operation
interface or aircraft planning plot interface, and other interfaces cannot
unlock the motor
Manual Landing Pull the throttle lever down until the aircraft lands on the
ground. After the aircraft landing, the motor can be stopped in the following
two modes: After the aircraft landing, pull the throttle lever to the lowest
position and hold 5s before the motor stops.
· The propeller rotating at high speed is dangerous, so you should keep a safe
distance from the aircraft and keep the aircraft away from people, animals or
other obstacles. · Be sure to keep the remote control in hand before the
aircraft motor stops and ensure that the aircraft is completely under control.
· Do not stop the motor during flight, otherwise the aircraft will fall.
Unless there are special circumstances (such as the aircraft may crash into
people), it is necessary to
stop the motor urgently to minimize the injury. · After landing, please turn off the aircraft first, and then turn off the remote control.
Electronic Fence
The electronic fence is turned on by default, which will limit the flying
height and maximum flying distance of UAV.
The flying height and the farthest flight distance (centered on the remote
control) of the UAV can be safely restricted in the APP setting of Huida UAV.
No-fly Zone According to the regulations of ICAO and air traffic control in
various countries on airspace control and the regulations on UAV management,
UAV must fly in the prescribed airspace. For flight safety reasons, the flight
restriction function is turned on by default, including no-fly zone
restriction and electronic fence restriction, to help users use HD540 more
safely and legally.
No-fly zones include the no-fly zone of the Global Air Traffic Control Bureau
and the no-fly zone defined by users. For UAV, UAV should not fly in the no-
fly zones. In the absence of positioning, after the UAV flying into the no-fly
zone, the aircraft will automatically land with positioning, and after
landing, it cannot take off in the no-fly zone.
Calibration before operation
Weighing calibration Before weighing and calibration, it is recommended to
empty the Pesticide box or seeding box. After the weighing calibration is
operated according to the prompt, first lift the Pesticide box or seeding box,
and then put it down after the prompt is put down.
Flowmeter calibration For the first time of using UAV for spraying, please
calibrate the flow meter first to avoid inaccurate amount per mu caused by
inaccurate flow
How to calibrate: First add more than 20L of clean water into the Pesticide
box, enter the home page of the agricultural UAV APP, click “Start Operation”,
the right setting drop-down, select the spray setting, click “Flowmeter
Calibration”, and wait for the system to complete the flow meter calibration.
If it fails, you can try again.
IMU calibration and compass calibration
Compass calibration is very important, and the calibration results directly
affect flight safety. Failure to calibrate compass may lead to abnormal
operation of aircraft.
Do not calibrate in areas with ferromagnetic materials, such as telephone
poles and walls with steel bars. Do not carry ferromagnetic materials with you
during calibration, such as keys and mobile phones. If the red light of
aircraft status indicator flashes after calibration, the calibration fails.
Please re-calibrate the compass. After successful calibration, put it on the
ground, and the compass is abnormal, which is probably due to metal objects
underground. Please change the position to check whether the anomaly is
eliminated.
How to calibrate 1.Enter the home page of agricultural UAV APP, click “Start
Operation”, and select “Aircraft Settings” from the setting drop-down on the
right
2.Select “Adjusted Settings”, select “IMU and Compass Calibration”, click
“Compass Calibration”, and follow the prompts on the interface. Two people
lift the UAV and turn horizontally in the specified direction. When the remote
controller prompts that the calibration is successful, the UAV can be put
down. 3.If the calibration fails, try again according to the above steps Note:
Before calibrating the compass, please connect to the network to maintain the
positioning information, and keep away from metal, signal transmission tower,
objects with strong electricity and magnetism, about 1 meter from the ground,
and rotate the aircraft horizontally for 3 circles or more.
click”IMU and Compass Calibration”

remote control.
Note: During flight, if the App text or voice prompts the aircraft battery to
be in a low power state, at this point, the aircraft should fly to a safe area
and land as soon as possible, and then the battery should be replaced; If the
App prompts that the battery of the aircraft is in a state of severe low
power, the aircraft will automatically land in place (at this point, the
flight cannot be controlled through the rocker, so please note the remaining
battery power at any time)
Plan Fields
UAV APP provides four modes to plan plots: RTK planning, aircraft planning,
remote control planning and map planning.
RTK Planning
For RTK planning, the RTK high-precision positioning module installed in
remote control is used for the measurement. For your safety, please ensure
that the aircraft power is turned off when using RTK planning. 1.Ensure that
the RTK high-precision positioning module is installed in the remote control
2.Turn on the remote control and slide down from the top of the screen to
ensure that the “USB” switch is ON 3.Enter the main interface of App, click
“Planning Plot”, and select “RTK Planning” 4.Enter > RTK settings, select RTK
signal source (Users outside Chinese Mainland only support RTK mobile stations
as RTK network sources), and complete the corresponding settings. Wait to
ensure that the RTK positioning status bar above the interface is green,
indicating that RTK positioning has been used 5.Walk along the boundary of the
area with the remote control held, click the “Add” icon at the inflection
point of the plot, and add the boundary point of the plot by default, and add
the boundary point to all the inflection points of the plot in turn to
complete the mapping of the plot boundary 6.Add obstacle points: For non-
circular obstacles, the planning method is the same as the planning plot. Walk
along the boundary of obstacles with the remote control held, select the type
of planning point as “obstacle point” at the inflection point of obstacles,
click the “Add” icon to complete the addition of obstacle points, and add
obstacle points to all obstacle inflection points in turn to complete obstacle
mapping. Note: When adding obstacles, for the sake of subsequent flight
safety, it is recommended that the boundary planning of obstacles should keep
at least 3m away from obstacles. Surely, you can also enter the plot editing
and unified adjustment after planning obstacles.
7.Add circular obstacles: Walk toward to the side of the circular obstacle
with holding the remote control, select the type of planning point as
“Circular Obstacle”, and then click the point on the edge of the circle of the
circular obstacle to drag and adjust the radius of the circular obstacle.
8.Intelligent flight course planning: After the plot is added, the flight
course will be automatically generated, and after the obstacles are added, the
flight course will automatically adjust the optimal flight course according to
the obstacles. 9.Add reference points: If necessary, one or more reference
points can be added outside the planned plot, which is convenient for flight
course correction based on RTK positioning of aircraft when the plot is
called.
Remote Control Planning The user need to walk along the edge of farmland or
obstacles with remote control held for measurement. For your safety, please
ensure that the aircraft power is turned off when using remote control
planning.
1.Power on the remote control, enter the main interface of App, click
“Planning Plot”, and select “Remote Control Planning” 2.Ensure that the
positioning accuracy is within 2m, and refer to RTK planning for other
operation steps (the same operation)
Flight Planning
The user could control the aircraft to the required position, and then add
waypoints through the remote control or App buttons to measure the edges and
obstacles of farmland.
Power on the remote control, enter the main interface of App, and then connect
the power of aircraft Click “Planning Plot”, select “Flight Planning” Unlock
the UAV and it takes off to hover in a safe area Other operation steps are
similar to those of RTK planning, you only need to control the aircraft
instead of walking with the remote control Note: After the plot is planned,
please save it before the modification. After saving, you can upload a plot to
the cloud for backup, in order to prevent it from being unable to recover
after error in modification.
Map planning
You can switch from other planning methods to map planning. After switching to
map planning, you can manipulate the touch screen to move the location icon to
plot the planned plot.
Note: The map planning suggests that the satellite positioning accuracy be re-
planned within 2 meters, otherwise the route may deviate from the plot due to
excessive deviation
Edit Fields
Edit the Flight Course
Adjust the indentation: The default adjustment is unified indentation, with a
minimum of 0m and a maximum of 6m, and 1.5m by default. You can click the
target sideline of the selected plot, and then edit the unilateral indentation
value.
Operation row spacing: 7m by default, 2m by minimum and 11m by maximum
Obstacle margin: 3m by default, 1.8m by minimum and 10m by maximum
When encountering obstacles: bypass by default and turn back optionally; this
is the route planning method when the flight route encounters obstacles, which
can be selected according to actual needs.
Adjustment of route direction
Support adjusting the direction by fine-tuning sliding, when each point is
subject to fine-tuning, adjust +1° or -1°.
Adjust the route direction quickly: Double-click the sideline of the target
plot, and the route will be parallel to the sideline.
Reverse route: Select the sideline of the target plot, and click “Reverse
route” to set the starting point to the other side of the sideline (quick
adjustment of route direction).
Edit Waypoint Move boundary point: Drag or move the position of the boundary
point of the plot by fine-tuning. After moving the boundary point, the route
will be intelligently planned again in real time. Delete the boundary point:
Delete unnecessary boundary points, the route will be re-planned intelligently
immediately. Add the boundary point: After adding the boundary point, the
route will be re-planned intelligently immediately.
Edit Obstacles Add obstacles: the same as planned obstacles, please refer to
planned circular obstacles and non-circular obstacles respectively Delete the
obstacle point: select an obstacle point and click Delete to delete the
obstacle point Delete the circular obstacle: click to select a circular
obstacle and click “Delete” to delete the circular obstacle Move the obstacle
point: Click to select an obstacle point, drag or move the obstacle point by
fine-tuning to the target position After editing the obstacles, the route will
be intelligently re-planned in real time
Add a Reference Point Select a relatively fixed symbolic point as the
reference point, and the subsequent route correction will be more convenient
and accurate
Delete a Reference Point Click a reference point, click “Delete” to delete the
reference point
Undo Operation If the operation of addition, deletion or movement needs to be
revoked, click the “Undo” button to complete the undo operation route

any error in segmentation operation, you can cancel Save and segment again in
the Save Plot dialog box
Work Mode
HD540 agricultural UAV has route operation mode, A-B point operation mode,
manual operation mode and enhanced manual operation mode, which can be
switched through agricultural unmanned aerial vehicle APP
Fully autonomous work mode After the user conducts farmland survey, obstacle
survey and waypoint setting through the intelligent planning operation system
of agricultural UAV APP, the App will calculate and generate the best route
based on these data to realize the intelligent planning of operation. After
the planning is completed, call the operation, and the aircraft will enter the
autonomous operation mode to automatically execute operations according to the
route. The HD540 agricultural UAV has the functions of intelligent departure,
intelligent supply reminder, abnormal interruption operation recovery, and can
use the Obstacle avoidance system for altitude determination and obstacle
avoidance. Users can adjust the amount of spraying/seeding, flight speed, etc.
in real time on the App interface. This mode is very suitable for regular or
irregular large plot operation.
A-B point work mode Users can map A-B points through the intelligent planning
operation system of agricultural UAV APP. After setting A-B points, adjust the
direction of A and B points and the parallel of the plot boundary, and then
set the number of routes to cover the plot. The App will calculate and
generate the best route based on the data to realize the intelligent planning
of the operation. After the planning is completed, the aircraft will enter the
A-B point operation mode and automatically perform the operation according to
the only planned route.
The HD540 agricultural unmanned aircraft has the functions of intelligent
departure, intelligent supply reminder, abnormal interruption operation
recovery, and can use the Obstacle avoidance system for altitude
determination, obstacle avoidance and
automatic obstacle avoidance.
Note: It is impossible to plan obstacles in the plot at point A-B. If there
are obstacles in the plot, it is recommended to use the Fully autonomous work
mode, plan the plot first, and then call to execute the operation.
Manual work mode For small plots or plots with many obstacles and complex
terrain, the manual operation mode can be used. The flight path of the
aircraft is completed by manually hitting the lever on the remote controller,
and the spraying or broadcasting switch needs to be manually turned on. At
this time, the UAV is not recommended to fly outside the range of sight
distance, otherwise flight safety risks may occur.
Enhanced manual work mode The enhanced manual operation mode can also be used
for large and medium-sized parcels that have no obstacles and are relatively
regular. Fly the aircraft to the expected route of the target, align the nose
with the expected route, set the amount of mu, flight speed, operation line
spacing, and relative crop height, and then click “Start”, and then hit the
rod in the forward direction. When reaching the headland, click “Left
Transverse” or “Right Transverse” as required to complete the lateral

FCC Statement Any Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment. This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
RF Exposure Statement for 3WWDZ-40-BU This device meets the government’s
requirements for exposure to radio waves. This device is designed and
manufactured not to exceed the emission limits for exposure to radio frequency
(RF) energy set by the Federal Communications Commission of the U.S.
Government.
The exposure standard for wireless devices employs a unit of measurement known
as
the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6
W/kg. *Tests for SAR are conducted using standard operating positions accepted
by the FCC with the device transmitting at its highest certified power level
in all tested frequency bands. Although the SAR is determined at the highest
certified power level, the actual SAR level of the device while operating can
be well below the maximum value. This is because the device is designed to
operate at multiple power levels so as to use only the poser required to reach
the network. In general, the closer you are to a wireless base station
antenna, the lower the power output.
For carrying around operation, this device has been tested and meets the FCC
RF exposure guidelines for use with an accessory that contains no metal. Use
of other enhancements may not ensure compliance with FCC RF exposure
guidelines.
The FCC has granted an Equipment Authorization for this device with all
reported SAR levels evaluated as in compliance with the FCC RF exposure
guidelines. SAR infromation on this device is on file with the FCC and can be
found under the Display Grant section of http://www.fcc.gov/oet/fccid after
searching on FCC ID: 2BBNT3WWDZ-40-BU

the radiator& your body.
Note : This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates,uses and can radiate
radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures: –Reorient or relocate the receiving antenna.
–Increase the separation between the equipment and receiver. –Connect the
equipment into an outlet on a circuit different from that to which the
receiver is connected. –Consult the dealer or an experienced radio/TV
technician for help.
