2. When the drone is flying, short press the "" button, the drone will automatically land on the ground.

Tips: Before flying, make sure the GPS Mode is turned on in case the drone gets lost!

FUNCTION DETAILS

Camera Angle Adjustment

During the flight, you can dial the wheel left /right to tilt the camera up/down. (The gimbal has an 90° tilt range.)

Return to Home (RTH)

• The Return to Home function brings the drone back to the last recorded Home Point.
• The Home Point is the location at which the drone takes off or the GPS receives a signal from 7 or more satellites for the first time during flight. The current position of the drone will be recorded as the Home Point.

Smart RTH

If the GPS signal is available (7 or more satellites reception) and the home point is recorded previously, press the "" button on the transmitter, then the drone will fly back to the Home Point.
Exit the RTH mode by pressing the "" button again or pushing the Throttle Joystick.

Failsafe RTH

If the GPS signal is available (at least 7 satellites) and the home point is recorded previously. Failsafe Return will be triggered if the transmitter signal is lost for more than 6 seconds. The drone will automatically start the return procedure and it will fly back to the last recorded Home Point. You can exit "Failsafe RTH" mode by pressing the "Return to Home" button or pushing the Throttle Joystick if the transmitter signal is recovered.

• During the Failsafe Return procedure, the drone can not avoid obstacles.
• The drone cannot Return-to-Home if the GPS signal is weak (satellites number is less than 7).
• If there is no GPS signal or the transmitter signal has lost for more than 6 seconds, the drone will not Return-to-Home but it can descend slowly until landing on the ground and locking the drone.

Low Voltage RTH

1. When the drone's rear lights flash slowly, the "" symbol is displayed on the screen of the transmitter, the First Low Voltage RTH will be triggered. And the drone will return automatically in the following two conditions:
   (At this time, the drone can only fly within a safe range of the height no more than 98 feet and the distance no more than 328 feet.)
   1. When the filght altitude is higher than 98 feet, the drone will fly back above the Home Point then descend automatically to 98 feet high and exit the First Low Voltage RTH.
      
   2. When the filght altitude is lower than 98 feet, the drone will elevate automatically to 98 feet high then fly back above the Home Point and exit the First Low Voltage RTH.
      
2. If the drone's rear lights begin to flash rapidly the "" symbol will be displayed on the transmitter screen and the transmitter will emit a "Di..., Di..." alert. The Second Low Voltage RTH is automatically triggered.
   1. When the filght altitude is higher than or equal to 50 feet, the drone will stay in the current altitude and return above the Home Point then desend vertically.
      
   2. When the filght altitude is lower than 50 feet, the drone will elevate automatically to 50 feet high then fly back above the Home Point and desend vertically.
      

Image Positioning System

The Image Positioning System consists of a camera module, which acquires the position information of the drone through visual images to ensure precise positioning and safe flight of the drone.

The Image Positioning System is typically used in indoor environment when GPS is weak or unavailable. It works best when the drone altitude is less than 5 meters.
When in a dark environment, you can turn on the lights by pressing the Light Switch button "" in the upper right corner of the transmitter to facilitate the image positioning function.

The precision of the Image Positioning System is easily affected by the light strength and features of the surface textures. Once the image sensor is not available, your drone will switch to Gesture Mode automatically. Be cautious to operate the drone in the following situation:

1. Fly fast at an altitude below 0.5m.
2. Fly over monochrome surfaces (like pure black, pure red, pure red and pure green).
3. Fly over strong light reflective surfaces or surfaces prone to reflection.
4. Fly over water or transparent object surfaces.
5. Fly over moving object surfaces (such as crowds, swaying juggles and glass).
6. Fly over an area where light changes dramatically and rapidly.
7. Fly over surfaces extremely dark (lux< 10) or extremely bright (lux> 10,000).
8. Fly over surfaces without clear textures.
9. Fly over surfaces with highly repeating textures (small grid brick in the same color).
10. Fly over surfaces that are tilting over 30 degrees (could not receive the echo of the ultrasonic wave).
11. Flying speed should be controlled not to be too fast. When drone is 1 meter from the ground, the flying speed should not be over 5m/s. When the drone is 2 meter against the ground, the flying speed should not be over 10m/s.

• Keep sensors clean at all times.
• The vision system is only effective when the drone is within the altitude range of 5 meters.
• Make sure that the light is bright enough and the surfaces is with clear textures so that the vision system can acquire the movement information through recognizing the ground textures.
• The vision system may not function properly when the drone is flying over water, low light ground and surfaces without clear patterns or textures.
