- position switch on the transmitter to the U channel of Fight controller as the
control mode switch, of which two positions are default as Atti. a nd GPS
Mode and the other position is optional,
users can set as Atti. or Manual Mode.© 201 3 DJI Innovations. All Rights Reserved 16 |

S tep 2. Toggle the control mode switch to its three positions, accordingly the cursor will move
to some control mode.

S tep 3.
Power off the Transmitter , the Failsafe will be enabled and the cursor will point to any area out of the control mode s
.

S tep 4. If all steps above are realized, t hat indicates
the control mode switch is set successfully

. Important
I n step2, if the cursor doesn ’ t point to the correct control mode area (e.g. the following figures ) , that indicates abnormal control mode switch configuration. U sers must re - configure t he Endpoint and FailSafe functions in the Transmitter to make the cursor right point to the control mode switch and the control mode area s become blue.© 201 3 DJI Innovations.

## 1.3 Compass Calibration
The Compass can assistant the GPS to position the aircraft, which is very impo rtant during flight. As we know, the compass is very sensitive to electromagnetic interference , which will cause abnormal compass data, and lead
to poor flight performance or even flight failure

. Compass Calibration MUST be done for the first time use. It is recommended to calibrate the compass outdoor s after the C ontroller U nit finds 7 or more GPS satellites

. Regular calibration enables the compass to keep optimal performance

. 

### Calibration Caution s (1) DO NOT calibrate your compass where there is strong magn etic interference, such as magnetite, car park, and steel reinforcement under the ground. (2) DO NOT carry ferromagnetic materials with you during calibration, such as keys or cell phones. (3) Compass Calibration is very important; otherwise the flight control sys tem cannot work. 

## Calibration Procedures Choose an open space to carry out the following procedures.

## 2. 2 Flying E nvironment R equiremen t s
(1) Before use of the product, please accept some flight training (Using a simulator to practice flying, getting instruction from a professional person, etc.). (2) D O N OT fly in bad weather, such as rain or wind (more than moderate breeze) or fog. (3) The flying field should be open without tall buildings or other obstacles; the buildings of steel structure will interfere with the compass. (4) Keep the aircraft away from obstacl es, crowds, power lines, trees, lakes and rivers etc. (5) Try to avoid interference between the remote control T ransmitter and other wireless equipment. (No base station or cell tower around) (6) The flight control system can’t work at the South Pole and the North Pole. (7) All parts must be kept out of the reach of children to avoid CHOKE HAZARD; if a child accidentally swallows any part you should immediately seek medical assistance.



## 2. 3 Check List before Flying
Double check the following list, otherwise, if any one of the following item s is wrong it may lead to flight accident

.

(1) A ll parts are in good condition , no ageing or damaged components (2) Motor rotating direction (3) Propeller mounting direction (4) Mixer Type set in assistant software (5) IMU and GPS

- COMPASS PRO mounti ng direction (6) T ransmitter channel mapping and sticks move ment direction correct (7) Compass calibration (8) ESC connection (9) IMU and GPS

- COMPASS PRO firmly mounted
In addition , check the following items to make sure the system can work.

(1) The Transmitter battery is fully charged. (2) The aircraft battery is fully charged. (3) Do not over load the aircraft.© 201 3 DJI Innovations. All Rights Reserved 21 |

Transmitter (Mode2) Aircraft Operations

Throttle
Stick Push Throttle sticks to control the aircraft to elevate and descend. The aircraft can lock to an altitude when the throttle stick is at midpoint.

Yaw Stick Push the yaw stick to rotate the aircraft in clockwise or counter clockwise direction.

Roll Stick Push roll stick to control the aircraft left or right , pitch stick to control forward or backward. When both roll and pitch sticks are at midpoint : (1) GPS mode : the aircraft will be stabilized and locked in horizontal position. (2) ATTI 1/ ATTI 2 mode : the air craft will be stabilized but unlocked in horizontal position. Pitch

### 4.Hover
In GPS mode , the aircraft will hover when the throttle/yaw/roll/pitch sticks are all released at mid

### 5.Landing
Use the throttle stick to control the land ing speed, try to land your aircraft gently to avoid shock or crash.

Please refer to the next section “ P rotection F unctions S etting” to take precautions. (1) Low voltage alert: yellow quick flashes or red quick flashes

. (2) FailSafe: LED indicator blinks blue

. Moreover , you may come across the following abnormal situation, please carry out the operation below. (3) Compass data is abnormal; the LED blinks yellow and green alternatively. P lease re

- calibrate the Compass. (4) IMU data is abnormal, the LED blinks four g reen. P lease contact your dealer.© 201 3 DJI Innovations. All Rights Reserved 24 |

once. If already in a Failsafe condition, then the switch will not work.



### Failsafe and Go H ome procedures

(1) The aircraft will not go home (only attitude stabilizing) i n the condition that <6 o r GPS is not working , even if Transmitter signal is lost or Go Home switch is triggered. (2) It is reco mmended to set the Go Home switch in the Assistant software. U sers are suggested to enter Failsafe and go home by using the Go Home switch rather than turning off the Transmitter in© 201 3 DJI Innovations. All Rights Reserved 25 | emergency situations. (3) M ake sure there are no obstacles during aircraft go home and users are familiar with the methods to regain control.

home in the follow ing cases : a) Control mode is in Control Mode 1 (M anual or ATTI 1) b) GPS signal is bad ( < 6 ) c) The distance between aircraft and the home point is less than 25m, and the height over the Home point less than 20m.


### D escending Usage Tips
T he aircraft will not hover when the throttle stick is at the mid point. Push the throttle stick to 90% of endpoint,
the aircraft will still ascend slowly if you continue to pull the throttle stick, and the control of Pitch, Roll and Yaw
are the same as bef ore.

Please pay atten tion to the LED alert of low voltage and make sure the power is enough for go home
and landing. I nsufficient power reserve will cause the aircraft to crash and other consequences.© 201 3 DJI Innovations. All Rights Reserved 26 |

## 4.2 Gimbal function

C onnect the servos of your gimbal to the Controller Unit as the fig. below , roll servo connect s to F3 port and pitch servo connect s to F 2 , and configure in Advanced

- > Gimbal page in the Assistant software. No Receive r
channel is asked to be mapped for the F2 or F3 port if gimbal function is enabled in the Assistan t Software. Note: Even you map Receiver channels to F3 and F 2 (Which are shown as D3 and D 2 in the Assistant Software

- > Channel Mapping), the F3 and F 2 will not give output signal s from the mapped Receiver channels.



## 4. 3 Gear function

Once enable the Intelligent Gear function , the gear is default down on the ground or in case of emergency (e.g. motor failure tolerance, auto landing); you can control it to be up or down by a switch when the aircraft altitude
is above 5m during flight. Please configure in the Advanced

- > Gear page in the Assistant software. C onnect the landing gear of S800 EVO

to the Controller Unit as fig. below.

(1) Make sure to enable and configure the Intelligent Gear function in the A ssistant software first, and then connect the gear to the F1 port. (2) T he Gear channel is required to be mapped with a channel on Receiver if the Intelligent Gear function is enabled in Assistant Software, and the F1 port will give output s for retracting control. (3) Once you map the Gea r channel, F1 port will give output signal s from the controller for retract control. Otherwise, even the Intelligent Gear function is enabled ; F1 will give output from D1 ( it ’ s
necessary to map the D1 channel with a channel on Receiver as your demands)
