   according to the un-fastening instructions.

Mounting the Landing Gears s with the Compass Module if Required

If the GPS Mode is desired, you must first mount the landing gear which contains the compass module.

1. Prepare aircraft and landing gears.
2. Mount the landing gear with compass module to the right part (shown as the following chart); make sure the 5-pin cable is through the hole of the landing gear. Fix the landing gear with screws (M3x6), and then connect the 5-pin cable to the compass module.
3. Mount the other landing gear to the left part.
4. Fix antennas and 5-pin cable on both landing gears by using the white adhesive tape.

1. When flying, please make sure the compass module is stationary and firm.
2. If the landing gear with the compass module mount on has been deformed, please replace it with a new one and mount it as the procedures above.
3. Compass module is not waterproof, and not anti-oil.
4. DO NOT use magnetic screwdriver. Otherwise, keep the screwdriver at least 10cm away from the compass module, to avoid magnetic interference.

Powering on the Transmitter

1. Set S1 and S2 switches to the upper most position and all sticks are at mid-point
2. Turn power switch to the right end to power on the transmitter.
3. There is a power on indicator beep. If the transmitter is set to be CE compliant, then there will be one beep while the FCC compliant version will emit 2 beeps. The power indicator blinks green quickly indicating the transmitter and receiver is linking. Once fully linked, the power indicator will change to a solid green.

Power Indicator Status Information

The transmitter will blink the LED and sound an alert when the voltage drops below 3.9V and automatically power off after 3 seconds.

Powering on the Aircraft

1. Place aircraft on the ground
2. Open battery compartment cover of the aircraft.
3. Put battery into the compartment with the power cord facing outward.
4. Connect battery and aircraft by the power lead and make sure the ESCs work properly. (Correct sound)
5. Keep all sticks of the transmitter and the aircraft stationary until the system start and self-check has finished
6. Put power cable into the battery compartment.
7. Close battery compartment cover.
8. LED flight indicator may blink Yellow 4 times quickly. Start motor is disabled during LED flight indicator blinking Yellow 4 times quickly, as the system is warming up.

1. Contact your dealer if the “System start and self-check LED flashes” are not correct (LED flight indicator appears red in the last four green flashes) in the Step5.
2. After the system start and self-checking has finished, if the LED flight indicator blinks Red, Yellow and Green continually, that means the IMU data is abnormal. The PHANTOM FC40 will not work, please connect to the NAZA-M V2 Assistant Software and follow the tips to do operation.
3. If it blinks red and yellow lights alternately, that means the compass error is too big, it can be caused by the following three cases. Please connect to the NAZA-M V2 Assistant Software, select the “Tools” tab and follow the tips of the “IMU Calibration” to do operation.
   • a) There are ferromagnetic substance around; first make sure that the compass has been calibrated correctly, you can lift the aircraft up (about 1m from the ground), and stay away from the surrounding possible ferromagnetic material object, if there is no red and yellow flashing after lifting it up about 1m from the ground, then it will not affect the flight.
   • b) Compass module had been put near a magnet; in this situation please timely replace the compass for a new one, otherwise it will lead to some abnormal action, or even loss of control.
   • c) Compass is not properly calibrated; in this situation please calibrate the compass correctly again, please see the “Compass Calibration” section for details.

Compass Calibration

If the compass module is not used, you can skip this step.

The GPS module has a built-in magnetic field sensor for measuring the geomagnetic field, which is not the same in different areas. The GPS module will not work unless the compass module has been connected. Make sure the compass module connection is correct.

Always keep the compass module away from the magnet. If this situation occurs please change the compass module before flying. Otherwise it may damage the compass module and lead the aircraft to work abnormally or even be out of control.

Calibrate the compass before the first flight or when flying in a different area. Make sure to keep away from ferromagnetic substance and other electronic equipment when calibrating or flying. If you keep having calibration failure, it might suggest that there is magnetic interference or other ferromagnetic substance, please avoid flying in this area.

If you have calibration failure or the LED flight indicator blinks red and yellow lights alternately, please connect to the Assistant Software, select the “Tools” tab and follow the tips of the “IMU Calibration” to do operation.

1. Quickly switch control mode switch from GPS Mode to ATTI. Mode and back to GPS Mode for 6 to 10 times, The LED flight indicator will turn to constantly yellow.
2. Rotate your aircraft around the horizontal axis (about 360 o ) until the LED flight indicator changes to constant green, and then go to the next step.
3. Hold your aircraft vertically and rotate it (its nose is downward) around the vertical axis (about 360 o ) until the LED flight indicator turns off, meaning the calibration is finished.
4. If calibration was successful, calibration mode will exit automatically. If the calibration has failed, the LED flight indicator keeps flashing quickly Red. Switch the control mode switch one time to cancel the calibration, and then restart from step 1.

GPS Mode -> ATTI. Mode -> GPS Mode is one time, quickly switch 6 to 10 times

Flight Test

Test Procedure

1. If in GPS Mode, place the aircraft in an open space without buildings or trees. Take off the aircraft after 6 or more GPS satellites are found (LED flight indicator blinks red once or no blinking). If in ATTI. Mode, you can skip this step.

2. Place aircraft 3 meters away from you and others, to avoid accidental injury.

3. Start-up

4. Switch on transmitter first, then power on aircraft! Keep the aircraft stationary until the system start and self-check has finished.

5. Please wait for system to warm up gradually with LED flight indicator blinks Yellow 4 times quickly. You should not start the motors until the blinking disappears.

6. Keep aircraft stationary, and execute any one CSC to start the motors.

7. Release yaw, roll and pitch sticks and keep them at neutral position, at the same time raise the throttle stick from the bottom. The motors will stop if you do not push the throttle stick from the bottom within 3 sec and you will need to re-start the motors.

8. Keep raising throttle stick until all the motors are working, push the throttle stick to the mid position and then
   take-off your aircraft gently, pay attention not to push the stick excessively.

9. Pay attention to the aircraft movement at any time, and use the sticks to adjust the aircraft’s position. Keep the yaw, roll, pitch and throttle sticks at the mid position to hover the aircraft at desired height.

10. Lower aircraft slowly until touch down is achieved. The motors will stop automatically after 3 seconds, or you can repeat the start-up stick command to stop the motors sooner.

11. Please always power off aircraft first, and then switch off transmitter after landing.

12. At the first motors start, the system will check the sensors Bias and you are asked to keep the aircraft stationary (no need of horizontal level). If you cannot start the motors and the LED flight indicator blinks Green 6 times quickly ( ), it means that the sensor error is too big. Please connect the NAZA-M V2 Assistant Software, enter the “Tools” – > IMU calibration, carry out the basic calibration. Note: after the first successful motors start, this checking will be disabled and it is no need any more to keep the aircraft stationary during starting motors.

13. If in GPS Mode, keep the aircraft flying in the open space without obstruction. Pay attention to the GPS satellite status indicator. When the GPS signal has been lost for 3s (LED flight indicator blinks red twice or three times), the system enters ATTI. Mode automatically.

14. If battery voltage is too low for flying, the aircraft enters the first level protection with LED flight indicator flashing quickly Red, please land ASAP. Once the aircraft enters the second level protection, the aircraft will drop height automatically.

15. If you want to put the PHANTOM FC40 in a car, please keep it away from the speaker, since the
    compass module may be magnetized.

16. DO NOT fly near to ferromagnetic substances, to avoid strong magnetic interference with the GPS.

17. It is recommended to land the aircraft slowly, to prevent the aircraft from damage when landing.

18. If transmitter indicates low battery alert, please land ASAP. In this condition the transmitter may cause the aircraft to go out of control or even crash.

The Failsafe and How to Regain Control

Introduction of Go-Home and Landing

Home-point : Every time you power on, after first motors start, and if 6 or more GPS satellites are found (LED flight indicator blinks red once or no blinking) for 10 seconds, the current position of aircraft will be saved as home-point by controller automatically.

1. Please make sure to record the home-point during flight, and clearly know where it is.
2. During go-home the nose direction of the aircraft is facing toward the home-point, and the aircraft is flying directly from the current position to the home-point.

The flowchart of failsafe and how to regain control

This section will demonstrate the working logic of failsafe and how to regain control. The following description is effective only when:

1. The aircraft is in flight.
2. The GPS works normally and signal is GOOD (≥6 satellite, the LED flight indicator blinks a single red light or no red light).

–What triggered failsafe
–The aircraft behavior after failsafe
–How to regain control
–Precautions

Low Voltage Alert

Low Voltage Alert is to indicate that the battery cannot provide enough power for the aircraft, in order to warn you to land the aircraft ASAP. There are both first level and second level protections. You should land your aircraft ASAP to prevent your aircraft from crashing or other harmful consequences!!!

In ATTI. Mode & GPS Mode.

• First level protection has LED flight indicator warning.
• During second level protection the aircraft will land automatically with LED flight indicator warning. Meanwhile the center point of throttle stick will move up slowly to 90% of endpoint, you should land ASAP to prevent your aircraft from crashing! When the center point is at 90% of endpoint, 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 before.

1. Configure the FailSafe function in the NAZA-M V2 Assistant Software – – > “Advanced” – – > “F/S” and read the instruction thoroughly and carefully.
2. Configure the Low Voltage Alert function in the NAZA-M V2 Assistant Software – – > “Advanced” – -> “Voltage” and read the instruction thoroughly and carefully.

PHANTOM RC Assistant Software Description

IOC Function

The IOC function should be enabled in the NAZA-M V2 Assistant Software.

Conditions of IOC function

Step 1 IOC switch setting

Please enable the IOC function in Advanced- -> > IOC page of Assistant Software. Then choose a 3-positon switch on the Transmitter to set as IOC switch, which is used to select the different IOC modes and manually record the Forward direction and HP recording.

Below is the IOC switch setting which may be configured in the Assistant Software.

Above table is for example. The function of the switch position may be reversed since the normal/reversed setting of the switch channel. Toggle the switch and observe the slider position of channel X2 on the Assistant Software screen, the corresponding area should turn blue.

Step 2 Forward direction and HP recording

After you enable the IOC in Assistant Software, the flight control system will record the forward direction and home point automatically after powered on, if the recording conditions are met. You can Manually re-record the forward direction and home point during flying. Read the following table for the recording method details.

1. DO NOT toggle the switch between the OFF and Home Lock positions frequently, which may re-record the Forward Direction.
2. HP is used not only in IOC, but also in Failsafe. The flight control system will automatically record the HP even if IOC function is disabled in Assistant Software but Forward direction can be recorded only after IOC is enabled.

Step 3 IOC flying test

DO NOT toggle the IOC switch frequently in HL flying to avoid re-recording the HP unwittingly.

IOC function is available only when all the required conditions are satisfied. If any condition is omitted the flight control system will exit IOC. Please keep an eye on the LED flight indicator to know the current control mode.

1. It’s recommended to start the HL flight when the aircraft is >10m away from the HP. If starting the HL when the distance between aircraft and HP is less than 10m and it’s the first time you start HL after power on, then the flight control system will only enter HL after flying out of the 10m range.
2. During HL flying if one of the following conditions occur, the flight control system will exit HL and enter into CL: the aircraft is within of 10m from HP; the control mode is changed to ATTI; GPS satellite number<6 (The LED flight indicator blinks red twice or three times).
