Matters That Need Attention
For safety reasons, please pay serious attention to all following items:
1.
For big aircraft that is larger than 650 or with heavy load, WKM is recommended.
2.
When aircraft is set-up with all of the equipment that you are going to use, please ensure the aircraft center
of gravity is on the center Line of the frame, this is for aircraft with its load is in the vertical direction of
frames center.
3.
When MC mounted, try your best to mount the MC at the center of the frame, and do not mount the MC
upside-down. Make sure MC is parallel to the aircraft horizon, so as to prevent the aircraft from drifting in
horizontal direction.
4.
Make sure the MC ESC ports is pointing to the aircraft nose direction, otherwise serious damage will occur
to your aircraft.
5.
Disconnect ESCs and battery or remove all propellers during firmware upgrade, configuration and system
setup!
6.
You have to reboot MC and redo the TX calibration after you change anything on the RC system.
7.
In the TX Calibration of assistant software:
8.

Throttle: Slide left is craft down, slide right is craft up;

Rudder: Slide left is nose left, slide right is nose right;

Elevator: Slide left is craft back, slide right is craft front;

Aileron: Slide left is craft left, slide right is craft right.
When powering up the Craft, Make sure you turn on the Transmitter switch first, then Plug in the FC
Battery power on multi-rotor before takeoff! After your Flying Session and you want to power down, make
sure you Remove Power to the multi-rotor first, and then switch off the transmitter!
9.
Whether you are using gimbal control in assistant software or not, there is always power output from F1 and
F2 ports. Do not connect these ports to any ESCs which are wired with propellers and motors.
10.
Do NOT set the failed-safe position of throttle under 10% of endpoint.
11.
Throttle stick position should always be higher than 10% from cut-throttle during the flight!
12.
The NAZA-M LITE-M has Low voltage protections! If you are seeing a Red Flashing light, you should land
your multi-rotor ASAP to prevent your multi-rotor from crashing or other harmful consequences!
13.
when using the (Immediately mode) to stop the motors, this is in any control mode, once the motors start
and throttle stick is over 10%, When the throttle stick lowered below 10% the motors will stop
immediately .But if you push the throttle stick over 10% within 5 seconds after motors stop, the Motors will
re-start; Combination Stick Command (CSC) is not needed. If you don’t push throttle stick after motors
start in three seconds, motors will stop automatically.
14.
By using Intelligent mode to stop motors, the motors will start or stop immediately when you execute CSC.
©2013 DJI Innovations. All Rights Reserved.
6
During normal flight conditions, you only have pull throttle stick under 10% will not stop the motors in any
control mode. You have to execute CSC to re-start motors if the motors stop during the flight.
15.
Red light quick blinking indicates battery voltage is low, please land ASAP.
16.
Do NOT move any command sticks during system start and self-check! Please contact us if the last four
green blinks are abnormal.
17.
GPS/Compass is sensitive to magnetic interference; you should be as far away from any electronic devices
as possible.
18.
Do not fly in GPS Mode when the signal is not good (red light blinks)!
19.
GPS module is optional (Nonstandard). If you are using the GPS module, please read the Instructions about
GPS matching in indicators; users without the GPS module can skip contents about GPS.
20.
If users set GPS Atti. Mode in Control Mode Switch without connecting to GPS module, the M.C. will switch
GPS Atti. Mode into Atti. Mode automatically, and LED indicator will Blink yellow.
21.
If you are working in the Fail-Safe Mode, with GPS on, the aircraft motors will auto Automatticly shut off
when the craft has landed; without GPS the aircraft will not auto shut off when landed.
22.
The receiver should be installed under the bottom board of center frame, and the head of antenna is
downward without any obstacles, this will help prevent any signal loss during flight and the aircraft will be
out of control, since the Radio signal may be lost by the obstacle.
23.
Make sure all connections are correct and attachment contacts are in good condition before flight.
24.
Keep wireless video transmission equipment a distance away from the main controller (>25cm), to prevent
the main controller from getting any interference from the Wireless Video Transmitter.
25.
If you use a gimbal, please make sure that the working current of the servos should not exceed the power
supply capacity of the VU; otherwise, it may cause the VU safeguard and lead to the main controller reboot.
Refer to the Specification section in the Appendix to get more VU parameters.

STEP1:
Mixer Type
Set your transmitter into ACROBATIC mode. Then select the right mixer type according to your multi-rotor.
Tips:

We support six types of multi-rotors. Refer to Multi-Rotors Supperted in Appendix:
Notices:

Do NOT follow instruction from 3rd party multi-rotor manufacturer! Make sure the rotation direction of
each motor is the same as the way up figure shows. If not, switch any of two wire connetcions of the
incorrect motor to change its rotation direction.

Make sure the type of propeller matches the rotation direction of the motor.
STEP2: Motor Idle Speed
Motor Idle Speed is the lowest speed after motors start. Setting the Motor Idle Speed will affect the motors lowest
speed after the motors start. There are five levels from LOW speed to HIGH speed, and the default is
RECOMMEND. You can click and drag cursor
LOW
to the corresponding level, to change Motor Idle Speed.
RECOMMEND
The lower motor idle speed
HIGH
The higher motor idle speed
Setting the Motor Idle Speed as LOW, the motor idle speed will be at its lowest point.
Setting the Motor Idle Speed as HIGH, the motors idle speed will be at its highest.
RECOMMEND is the advised level.
You can reset the Motor Idle Speed according to your personal preference.
Notices:

For users whose aircraft takes off at lowest throttles position, please set the idle speed at a low level.

STEP2: Cut Off Type
Please read the introductions of start and stop motor in this step first, and then choose a cut off type.
1
Start Motor: Pushing throttle stick before takeoff will not start the motors. You have to execute any one of
following four Combination Stick Commands (CSC) to start the motors:
©2013 DJI Innovations. All Rights Reserved.
15
Stop Motor: We provide two options to stop motors: Immediately and Intelligent.
2

Immediately Mode: If you select this mode, in any control mode, once motors start and throttle stick is
over 10%, motors will not stop immediately only when throttle stick is back under 10% the motors will
stop. In this case, if you push the throttle stick over 10% within 5 seconds after motors stop, motors
will re-start, CSC is not needed. If you don’t push throttle stick after motors start in three seconds,
motors will stop automatically.

Intelligent Mode: By using this mode, different control mode has different way of stopping motors. In
Manual Mode, only executing CSC can stop motors. In Atti Mode or GPS Atti. Mode, any one of
following four cases will stop motors:
a)
You don’t push throttle stick after motors start within three seconds;
b)
Executing CSC;
c)
Throttle stick under 10%, and after landing for more than 3 seconds.
d)
If the angle of multi-rotor is over 70°, and throttle stick under 10%.
Tips (Intelligent Mode):

You have to execute CSC in order to re-start the motors. By pushing the throttle stick only will not
re-start the motors.

In Atti. / GPS Atti. Mode, it has landing judgment, which will stop motors.

Start motors in Atti. / GPS Atti. Mode, you have to execute CSC and then push throttle stick over 10%
within 3 seconds, otherwise motors will stop after 3 seconds.

During normal flight, only pulling the throttle stick under 10% will not stop motors in any control mode.

For safety reasons, when the slope angle of multi-rotor is over 70° during the flight in Atti. / GPS Atti.
Mode (may be caused by collision, motor and ESC error or propeller broken down), and throttle stick is
under 10%, motors will stop automatically.

You can stop motors by executing CSC in any control mode.
Notices:

Any of these two cut off types will only work properly if TX calibration is correct done.

The motors will start or stop immediately when you execute CSC when TX commands are valid under any
of the control modes. It has nothing to do with current throttle stick position. Please DO NOT execute
the CSC during flight unless safety is at stake.

If you choose the Immediately mode, you should not pull throttle stick under 10% during flight, because
that will stop the motors. If you do it accidentally, you should push the throttle stick over 10% within 5
seconds to re-start the motors.
©2013 DJI Innovations. All Rights Reserved.
16
If you choose the Intelligent mode, and the throttle stick is under 10%, this will trigger the landing

Procedure, in any control mode. In this judgment, pitch, roll and yaw controls are denied except the
throttle, but multi-rotor will still auto level.

In any control mode, DO NOT pull throttle stick under 10% during normal flight without any reason.

In failed-safe, CSC is denied by MC, motors will hold their state.
STEP3: Command Sticks Calibration
Slides Moving Definition:
T
: If you pull the throttle stick to low position, the Slide will move to the left and the craft is down, Moving
the Throttle stick up the slide will move to the right is craft will lift off the ground;
R
: If you move the rudder stick to the Left the Slide will move to the left, this is nose left, When you move
the rudder to the Right the slide move to the right, this is nose right;
E
: If you move the Elevator stick down the Slide will move to the left and the craft will move back, Moving
the Elevator Stick up the Slide will move to the right and the craft will move Foward (away from you);
A
: If you move the Aileron stick to the left the Slide will move left and the craft will move to the left, when
you move the Aileron stick to the Right the slide will move to the right and the craft will move to the right.
1.
Set endpoints of all channels to default values (100%) and set all trims and sub-trims of sticks to 0 on
your transmitter first. Keep all curves’ settings as default since the end-point of transmitter sticks will be
recorded here.
2.
Click the START button, and move all of the sticks throughout their
complete range several times.
3.
After you do this, click the FINISH button when you have finished the
above procedures.
4.
If the slides are moving opposite from your stick movements direction, click the reverse button
REV/NORM beside.
Notices:
1.
All slides should become
when all the sticks are in the middle positions. If slides cannot go back to
center points (become ), just click FINISH, then slides will be at center automatically. If still not, please
reboot MC, and do not apply TX command during the reboot.
2.
CSC may not start motors If trims and sub-trims of sticks are not 0!

your RC correctly.
STEP5: Control Mode Switch
Whether you are using a 2 or 3 position switch on your transmitter will determine which you will use as the control
mode switch, Plug in the right channel of receiver (Gear, Aux 1 or aux 2) to the U port of MC. At each switch
position, use the end-point for fine tuning on your transmitter, Move the Switch to the corresponding Mode as
indicated by the slider of channel U to GPS (GPS Atti Mode), A (Atti. Mode), M (Manual Mode) to turn the
corresponding area blue respectively as showed in the figure.
Tips:

To move the slider is to adjust channel-selected end-points.

reverse the assignment for Position-1 and Position-3.

For 2-positions switch, you can assign any two of these three control modes as you like.
If your transmitter supports Fail-Safe, follow the Fail-Safe setting procedure of your R/C TX. Then move the slider
to the range which makes Fail-Safe Mode turn blue, set Fail-Safe output of receiver to input port-U. If you switch
off your transmitter now, the U channel slide should move to Fail-Safe and turn the corresponding area to blue.
Otherwise please reset the fail-safe. MC has built-in auto level Fail-Safe function. That means when the
communication between MC and transmitter is disconnected, the outputs of all command sticks from MC will go to
center point. If your transmitter has only 4 channels, then MC will work in Atti. Mode by default without the
Fail-Safe function.
Tips:
Please refer to your RC manual for the details of fail-safe setup.
With GPS, it is Enhanced Fail-Safe; without GPS, it is Auto Level Fail-Safe, and the aircraft will land.
Notices:
1.
Do NOT set the fail-safe position of throttle under 10% of endpoint.
2.
MC will not execute the Fail-Safe protection if you don’t set it properly. You can verify the
Fail-Safe settings by shutting down your transmitter, and then you can use the following
method to check whether MC is already in Fail-Safe mode.
3.
Check status bar at the bottom side of the software interface. If the Fail-Safe has been correctly set-up
the Control mode will change to Fail-Safe.
4.
Check the LED indicator. Read the appendix in this manual for details. LED will give fast yellow blinking

If users set GPS Atti. Mode in Control Mode Switch without connecting to GPS module, the M.C. will
switch GPS Atti. Mode into Atti. Mode automatically, and LED indicator will Blink yellow, that is if the
3-poisition switch is the same as 2-position switch.
8.
Once the MC goes into the Fail-Safe Mode, and you are using the GPS, the aircraft will auto Stop the
Motors when landed; without GPS the aircraft the motors will not auto Stop when landed.

4 Autopilot
STEP1:
Basic Parameters
Usually, the default parameters are ready to go. However, different multi-rotors have different gains because of
different Motor KV ratings, ESC and propeller sizes. If the gain is set too High, you will find the multi-rotor will be
oscillating in the corresponding direction (About 5~10Hz). If the Gain is too low, the multi-rotor will likely to be hard
to control. So you can still setup the basic Gain of Pitch, Roll, Yaw and Vertical manually according to your
multi-rotor to have a wonderful flying experience. We suggest you to change 10% to 15% of the parameter at a
time.
For the gains of the Pitch and Roll, if you release the Pitch or Roll stick after giving a command, the multi-rotor
should go back to a hovering state. If the reaction of multi-rotor in this procedure is too soft (large delay), please
increase the basic gain slowly (10%-15% each time) after you release the stick until vibration begins, . Then
decrease the gain a little until vibration just disappears. Now the gain is perfect, but the reaction of the attitude
change is slow. Follow the Procedure at the end of this section to tune the attitude gains.
The way of tuning the Yaw gain is the same as the way of adjusting the Tail Gyro. If you want fast stick reaction
speed, increase the gain, otherwise decrease the gain. However, the spin of multi-rotor is produced by the counter
torque force, and the magnitude of which is limited. Therefore, large gain will not produce tail vibration like
helicopter, but severe reaction at the start or stop of motors, which will affect the stabilization of the other
directions.
You will use two methods to judge if the Vertical gain is good enough: 1) The multi-rotor can lock the altitude when
the throttle stick is at center position; 2) The change of altitude is small during the flight along a route. You can
©2013 DJI Innovations. All Rights Reserved.
20
increase the gain slowly (10% each time) until the vibration emerges along the vertical direction or the reaction of
throttle stick is too sensitive, then decrease 20% of the gain. Now it is a suitable Vertical gain.
Attitude gains determine the reaction speed of attitude from command stick, the Larger the value the quicker the
reaction. Increase it for sharper and quicker leveling action after command stick released. Unstable shaking flying
and the control feeling will be stiffness and rigid if the value is too high; and sluggish leveling action and slow
braking if too small.
Notices:

You must upgrade firmware first, then click Default button in first setup parameter.

The vertical gain will NOT affect the manual mode.

The final flight performance is decided by the autopilot parameters and all parts of multi-rotor (includes
mechanical structure, motors, ESCs, propellers and battery). If these parts are not compatible, you cannot
get good flight performance by adjusting the autopilot parameters. Therefore, if you have high
requirement to flight performance, you’d better get a multi-rotor with good integration test.
Tips:

If you are new to multi-rotor flying, you can tune the basic parameters first as following:
1
Increase the basic parameters 10% at a time so as to make your multi-rotor hover or light oscillate
after small angular command input.
2

Decrease the basic parameters until your multi-rotor can just hover, then decrease 10% more.
Here you can make use of remote gain-tuning channels to tune the gains during the flight:
1
Followed the instructions in Assembly R/C System section to connect and setup correctly;
2
Choose the X1 or X2 channel in Remote Adjust for the gain you want to tune. One channel to one
gain.
3

The range of remote tuning is from half the current value to twice the current value.
Usually the Pitch, Roll, Attitude Pitch and Attitude Roll Gains of hexa-rotor are high then quad-rotor.
STEP2: Enhanced Failed-Safe Methods
Without GPS, please skip this step
Enhanced Fail-safe method will be triggered when MC loses the control signal, no matter what mode you fly. This
could be one of the following situations:
1)
Signal lost between transmitter and receiver, e.g. multi-rotor is out of the communication range, or
transmitter is down, and so on.
2)
One or more connections of A, E, T, R, U channels between MC and receiver loses. If this happens before
take-off, motors will not work if you push the throttle stick; if this happens during the flight, LED yellow light

will flash to warn in addition to the failed-safe method.
Choose one method for your failed-safe function, Landing: or Go Home and Landing.
Landing: the aircraft will land after 6s hovering.
Go Home and Landing: Before takeoff, current position of multi-rotor will be saved as home point by MC
automatically when you push the throttle stick first time after 6 or more GPS satellites are found (
blinks once or
no blinking) for 8 seconds.
Notices:
When switch to Manual Mode or Atti. Mode, MC will disengage enhanced failed-safe mode, you can re-gain
control of multi-rotor.

STEP3: Intelligent Orientation Control
Without GPS, please skip this step
Forward Direction: Multi-rotor will fly along this direction when you push the
elevator stick.
Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By using Intelligent
Orientation Control (IOC), wherever the nose points, the forward direction has nothing to do with nose direction:

In course lock flying, the forward direction is the same as a recorded nose direction. See the following
figures (Mode 2):


If you use S-Bus/PPM receiver, the default channel connection is shown in TX Monitor – Receiver
Type section. Then you only need to assign a 2 or 3-position switch of your transmitter to the 6th
channel.
Notices:
Do NOT set a 2-position switch as: Position-1 is Course Lock; Position-2 is Home Lock.

Close course lock: There are two ways:
a)
Slide X2 channel switch to OFF position to quit course lock; (Recommended way!)
b)
Slide U channel switch to Manual Mode position, or close transmitter.
STEP4:
Re-open course lock: If you want to re-open course lock after you quit this function, you should
first slide X2 channel switch to OFF position, and slide U channel switch to Atti. or GPS Atti. mode
position, then slide X2 channel switch to Course Lock position to re-open course lock.
Home Lock Usage:

by MC automatically when you push the throttle stick for the first time after 6 or more GPS
satellites have been found (
b)
blinks once or no blinking) for 8 seconds.
Manually: When 6 or more GPS satellites are found (
blinks once or no blinking), you can toggle
the X2 channel switch between (to a 3-position switch) Course Lock and Home Lock or (to a
2-position switch) OFF and Home Lock position quickly 3 to 5 times to record the current position
of the multi-rotor as the new home point. And LED will blink
STEP2:

Open home lock: flip the X2 channel switch to the Home Lock position to fly in home lock when all
the following requirements are met:
a)
Home point is recorded successfully;
b)
6 or more GPS satellites are found;
c)
In GPS Atti. Mode;
d)
Multi-rotor is further than 10m away from the home point.
Now wherever the nose is pointing, the real flight forward direction is the same as the direction from the
home point to the multi-rotor, and LED will blink between yellow and green

IOC mode of MC.
STEP3:
Close home lock: There are three ways:
a)
Flip the X2 channel switch to the OFF position to quit home lock; (Recommended way!)
b)
Flip the U channel switch to Manual Mode position, or turn off the transmitter.
c)
The MC will be in course lock by the current forward direction automatically when multi-rotor flies
back into 10m range around home point, or MC is in Atti. Mode.
STEP4:
Re-open home lock: If you want to turn on home lock after you quit this function, you should first
flip the X2 channel switch to the OFF position. When all 4 requirements in the 3rd step are met, flip the
X2 channel switch to the Home Lock position to turn on home lock.
Tips:
1
LED will blink between
and
slowly to indicate the IOC mode only when MC is really to fly in course
lock or home lock modes.
2
We suggest that you should know clearly that, by which lock method you are going to fly, and the locked
forward direction or home point, before you switch on IOC mode during the flight.
3
There is only one home point recorded at any time. This point is the same one used by Go-Home and
Landing in the fail-safe mode.
4
When flying by home lock, if GPS signal becomes weak, MC will be in course lock in the current forward
direction automatically.
5
You’d better stand near the home point to use home lick.
6
You’d better use 3-position switch for X2 channel, and you’d better use X2 channel switch to activate
and deactivate the IOC during the flight.
Notices:
1
Before you do the home lock flight, you have to fly the multi-rotor out of the 10m range around the home
point; you have to flip the X2 channel switch to Home Lock position to fly in home lock when all the
requirements are met. If you have already toggled the X2 channel switch to Home Lock position when
the multi-rotor is still in 10m range around home point, and this is the first time you are going to fly in
home lock during the current flight, then if all the requirements are met, MC will change into home lock
automatically when multi-rotor flies out the 10m range around home point.
2
When multi-rotor is flying by home lock, far away from you and the home point, please do not toggle the
X2 channel switch many times quickly so as to avoid the change of home point without you knowing it.
3
By using a 3-position switch, if you want to record the forward direction or home point manually, do not
toggle the X2 channel switch between OFF and Home Lock position, but only between OFF and Course
Lock, or Course Lock and Home Lock position. And please record the forward direction and home point
separately so as to make sure the recording is successful.

We suggest you to use Home Lock in a limited area which is 10m away from the home point.
5
Continuously spinning will cause a yaw error. In this case, you can stop or slow down the spinning, so as
to have better flight performance.
6
When flying in Home Lock mode, if any of the following situations happen, then the system will quit
Home Lock flying and automatically enter Course Lock flying. The aircraft will fly in Course Lock using
the earlier forward direction

The aircraft fly’s within 10m range of the home point.

You toggle the control mode switch to the ATTI. Mode.

The GPS signal becomes bad (The GPS signal LED is blinking Red twice or three times).

5 Gimbal
STEP1:
Gimbal Switch
If you use gimbal, please choose On here, and select an Output Frequency (50Hz/100Hz/200Hz/400Hz).
The chosen output frequency is recommended no more than the maximum servo supported frequency.
Notices:
If you open the gimbal control in assistant software during the configuration, please note that there are outputs
from F1 and F2 ports. You should never connect these ports to ESCs which are wired with propellers and
motors.
Tips:
NAZA-M LITE supports servo center 1520us.
STEP2: Servo Travel Limit
Range: -1000 to+1000
MAX/MIN are servo travel limits; adjust them to avoid mechanical binding; Place your multi-rotor on level ground,
adjust Center value of Pitch and Roll direction to make the camera mounting frame to your desired
angle-to-ground.
STEP3: Automatic Control Gain
©2013 DJI Innovations. All Rights Reserved.
27
Range: 0 to 100
Adjust the reaction angle of the automatic control. The initial value of 100 is the maximum angle. The larger the
gain, the bigger the reaction angle. Click REV/NORM, and then you can reverse the feedback control directions.
STEP4: Manual Control Speed
Range: 0 to 100
You should assign one of the knobs on your transmitter to the X1 channel for controlling the Pitch direction (angle)
of camera gimbal during flight first. Then adjust the reaction speed of pitch direction manual control; the initial
value 100 is the maximum speed.
Notices:
If parameter adjustment was enabled on channel X1, the gimbal manual control via channel X1 will still be on as
well.
Do not use X1 to control gimbal pitch and remote adjust parameters at the same time.
Please reset the Basic Parameters in Autopilot section if there is flight jitter after gimbal is mounted.

6 Voltage Monitoring
STEP1:
Protection Switch
In order to prevent your multi-rotor from a crash or other harmful consequences caused by low battery voltage,
there are two levels of low voltage protection available to use. You can choose to use or not to use them, however
we strongly recommend using the protections available!
Notices:

Make sure the connection between VU and MC (V-SEN to X3) is correct; otherwise the low voltage
protection will not work properly.

Both levels of protection have LED warning as default. Both levels of protection will blink red
continuously.

Both level protections will only have the LED warning under Manual Mode, none in the automatic actions.

Low voltage protections are NOT fun! You should land your multi-rotor ASAP in any level of protection
to prevent your multi-rotor from crash or other harmful consequences!
STEP2: Battery
Apply battery power the MC and connect the MC with the PC, current battery
voltage will be displayed in this column. If the battery voltage displayed here is
different from the voltage you measure from a voltmeter, you
have to
calibrate it. Click the Calibration box, enter that voltage in the Calibration
©2013 DJI Innovations. All Rights Reserved.
29
column of the dialogue box, and then click Confirm.
Meanwhile you need you to choose the battery type you are using, so that MC can provide the default warning
voltages and ranges for you.
STEP3: First Level Protection

No Load (No Load Voltage): Self-defining warning voltage. Needs your input.

Loss (Line Loss Voltage): The battery voltage drop during the flight. Needs your input.

Loaded (Loaded Voltage): The real-time battery voltage during the flight. This is the actual warning voltage
monitored by MC. Doesn’t need your input, calculated by No Load and Loss.
Tips:
Voltages Magnitude Relation:

No Load: First level > Second level.

Loss: First level = Second level.

Loaded: Calculated, First level > Second level.
Method of Acquiring Line Loss Voltage:
1
Make sure you can fly your multi-rotor normally with a fully charged battery.
2
Use a fully charged battery, switch on the low voltage protections in assistant software, and observe the
current voltage. Fill a reasonable warning voltage in the No Load of first protection (We recommend to
fill a voltage 1V lower than current voltage and higher than minimum battery voltage rating in). Fill 0V in
Loss at the moment.
3
Fly the multi-rotor until the first level protection is triggered, and the red light
is flashing. Now land
your multi-rotor ASAP.
4
Connect the MC to PC, open the assistant and acquire new current voltage. The Loss (Line loss voltage)
is the difference between the new current voltage and the first level No Load voltage you filled in.
Notices:

If the line loss voltage of a battery is over 0.3V per cell (e.g. 3S battery over 0.9V), it’s because the
internal resistance of battery is high or the battery is too old, we suggest you to replace it!

Generally the line loss voltages vary with different makes of batteries. For the consideration of safety,
you’d better acquire all the line loss voltages of all your battery you are using, and fill the lowest one in
the Loss box.

When you change the payload or multi-rotor, you have to get new line loss voltages.

The line loss voltage will be larger after many times of use, you should get new ones after 30 times of
charging.
©2013 DJI Innovations. All Rights Reserved.
30

Make sure your ESCs protection voltage is lower than 3.1V (1S), otherwise low voltage protection will not
work.
Acquire the line loss voltage by the above method, and then fill it in Loss. Then fill a reasonable warning voltage in
the No Load.
Notices:
When red LED starts to blink, you should land ASAP!
STEP4: Second Level Protection
1
Fill the warning voltage and the line loss voltage in No Load and Loss by the method introduced in previous
step.
2
When the second level protection is triggered, the LED warning will be on. Meanwhile the center point of
throttle stick will move up slowly to 90% of endpoint, you should land ASAP to prevent your multi-rotor
from crash or other harmful consequences!
3
When the center point is at 90% of endpoint, multi-rotor will still start to ascend slowly if you continue to
pull the throttle stick back, and the control of Pitch, Roll and Yaw are the same as before. Please land ASAP
to prevent your multi-rotor from crash or other harmful consequences!

Flight
Digital Compass Calibration
Without GPS, please skip this step
Why calibrate the compass?
Ferromagnetic substances placed on multi-rotor or around its working environment will affect the reading of earth
magnetic field for the digital compass. It also reduces the accuracy of the multi-rotor control, or even reads an
incorrect heading. Calibration will eliminate such influences, and ensure MC system performs well in a non-ideal
magnetic environment.
When to do it?

The first time you install NAZA-M LITE on your multi-rotor.

When the multi-rotor mechanical setup has changed:
a)
If the GPS/Compass module is re-positioned.
b)
If electronic devices are added/removed/ re-positioned (Main Controller, servos, batteries, etc).
c)
When the mechanical structure of the multi-rotor is changed.

If the flight direction appears to be shifting (meaning the multi-rotor doesn’t “fly straight”).

The LED blinking, often indicates abnormality blinking when the multi-rotor spins (It is normal for this to
happen only occasionally)
What not to do:

Don’t calibrate your compass where there is strong magnetic interference, such as magnetite, car park,
and steel reinforcement under the ground.

DO NOT carry ferromagnetic materials with you during calibration, such as keys or cell phones.

You don’t need to rotate your multi-rotor on a precise horizontal or vertical surface, but keep at least
45° difference between horizontal and vertical calibration.

The GPS will not work in the polar circle.
Calibration procedure
STEP1:
Quickly switch the control mode switch from Manual. Mode to GPS ATTI. Mode and back to Manual.
Mode for 6 to 10 times, The LED indicator will turn to constantly yellow
STEP2:
.
o
Rotate your aircraft around the horizontal axis (about 360 ) until the LED changes to constant green
, and then go to the next step.
©2013 DJI Innovations. All Rights Reserved.
32
Hold your aircraft vertically and rotate it (its nose is downward) around the vertical axis (about 360o)
STEP3:
until the LED turns off, meaning the calibration is finished.
STEP4:
The LED indicator will show whether the calibration was successful or not.

If the calibration was successful, calibration mode will exit automatically.

If the LED keeps flashing quickly Red, the calibration has failed. Switch the control mode switch one
time to cancel the calibration, and then re-start from step 1.
Tips:
If you keep having calibration failure, it might suggest that there is very strong magnetic interference around
the GPS & Compass module, please avoid flying in this area.

Make sure you have done the configuration procedure correctly.

Any of the following mistakes will leads to a dangerous accident, double check all these items:


Rotation direction of motor is opposite

Propeller installation mistake

MC installation mistake

Wrong connection between MC and ESC
In Atti Mode, throttle stick center position is for 0m/s along the vertical direction. You must keep the
throttle position higher than 10% from stopping the motors during the flight!

Make sure you switch on the transmitter first, then power on multi-rotor! (Power off multi-rotor first, then
switch off the transmitter after landing!)

Please do the fly test and gain tuning with Atti. Mode in the open air without heavy winds!

In Atti Mode, after power on and before motors start, if
or
LED double blinks without move
any stick, this indicates that you have moved any sticks during system start up and check.
You will have
to reboot MC before you try to fly.
Test Fly
1.
Make sure your batteries are fully charged for your transmitter, MC and all the devices on your
multi-rotor;
2.
Check all connections and wirings, and make sure they are in good condition;
3.
Switch on the transmitter first, then power on your multi-rotor!
4.
Flip the control mode switch on your transmitter, and make sure it is working properly. Check it with LED
indicator to specify the current working mode for MC. See Appendix for details about LED indicator;
5.
Switch the system to Atti. Mode. Use any safe method to do the following test: Apply the throttle to 20%
slowly and make sure all the motors are working properly, and then try to push your sticks lightly in Roll,
Pitch and Yaw to feel if your multi-rotor moves to the corresponding direction. If not, go back to
Configuration Procedure and correct your settings.
6.
Push the throttle stick slowly within 3 seconds after executing CSC until all the rotors are working, and
then take-off your multi-rotor gently

Before Fly with GPS
Notices:

When system is powered on, you must not move your multi-rotor or sticks on transmitter until the system
initialization is finished (about 5 second).

Make sure the GPS signal is good, without red LED blinking. Otherwise multi-rotor will drift without stick
commands.

Please avoid using MC system in the following areas, where will GPS signal is most likely blocked:

Urban area with crowded buildings

Tunnels

Under bridges
Tips:
Should you find the multi-rotor does not track straight in forward flight, you might try re-mounting GPS in an

IMU Calibration
The IMU calibration is used if the aircraft is drifting or spinning in horizontal direction while hovering. Better
performance can be obtained by gyroscope calibration. Check IMU status after the status changed to ready, and
take action according to corresponding tips.
1.
Please keep the main controller stationary during calibration, and then connect to the assistant software.
2.
Click the IMU calibration in TOOL to enter calibration page.
3.
Click Check IMU Status after the status changed to ready.
4.
The autopilot system check and give tip for you.
5.
If IMU works abnormally, please contact us or our agents; if IMU calibration is necessary, please click
Calibration button; else if IMU works normally, calibration procedure may be skipped.
Notices:

You don’t need to put the aircraft on a completely horizontal surface, but make sure to keep it
stationary.
Tips:

IMU works normally if the value of X, Y and Z is between [-1.5,1.5].

IMU works normally if the sum of the squares of X, Y and Z is around 1.
