6.1 GPS POSITIONING/ HOME POINT SETTING
1.) GPS Positioning works ONLY when the GPS signal has no less than 6 satellites.
2.) Home Point is recorded when armed the motors with no less than 6 GPS satellites.
3.) You should be in an open place to search for the GPS satellites, it’ll take 3 mins to finish
the searching, and the GPS signal strength depends on the flying environment.

6.3 FAILSAFE MODE
The drone will enter into Failsafe Mode when the connection is lost from the transmitter. The
flight control system will control the quad copter to return to the home point and land
automatically. The Failsafe Mode helps to avoid further injuries or damages.
CONDITIONS WHICH ACTIVATE THE FAILSAFE MODE
(1) Transmitter is powered off.
(2) The flight distance is beyond the range of the transmitter’s signal transmission.
(3) The transmitter’s signal was interrupted by some other strong electronic interference.
To ensure that the X4 can return safely to its home point when GPS signal is lost, fly
the X4 in safe flight area.
If the quantity of GPS satellites drops below six for more than 20 seconds while the
X4 is returning home, the X4 will descend automatically.
The X4 will not avoid obstacles automatically while in failsafe mode.
!The RTH MODE only works when the GPS with no less than 6 satellites.
6.2 RTH MODE
ENTER/ EXIT RTH MODE
Press the RTH button for 1.5 secondS, and the drone will enter into RTH mode. The flight control
system will control the drone to fly back to the home point and land automatically. Press the
button again for 1.5 seconds to exit RTH mode.

Flying in the area nearby magnetic field would interfere the compass which need
re-calibration as above instructed.
8. COMPASS CALIBRATION
COMPASS CALIBRATION PROCEDURES
Please follow the calibrating procedures before the first flight.
1.) Hold the Throttle Stick to the left corner, and move the Aileron Stick left to right quickly until
the transmitter displays " Set Compass 1" (Mode 2);
Hold the Throttle Stick to the left corner, and move the Aileron Stick left to right quickly until
the transmitter displays " Set Compass 1" (Mode 1)
2.) Rotate the X4 horizontally clock-wise until the LCD screen displays " Set Compass 2"
3.) Put the X4 nose down and rotate it vertically counter clock-wise until the " Set Compass 2"
on screen disappears
4.) Calibration done.
Do not calibrate the compass in a strong magnetic field.
Do not carry ferromagnetic materials with you while calibrating the compass,
such as keys, cell phones, etc.
Compass calibration is required before the first time flight, otherwise the system may not work
properly. The compass is very sensitive to electromagnetic interference which can cause
abnormal compass data and lead to poor flight performance or even flight failure. Regular
calibration enables the compass is in optimum performance
.
Rotate the quadcopter

“Set Compass 2”
disappear
Rotate the quadcopter
