Three- axis stabiliz ation gimbal makes the camera steady so that it can shoot stable photos even fly with

hight altitude. And you can control pitchangle of the gimbal by Gimbal dial on R emote Controller or operate

in the APP interface.

You must select the mode first and then adjust the angle. In follow me mode, the horizontal angle

(YAW) is not adjustable.

Gimbal stick position determines the rate of change of the gimbal: when the stick located at the

midpoint the velocity is zero, the greater the offset of the stick gimbal changes faster, whereas the slower.

Adjust the brightness of the camera shooting screen (APP operation)

Starlight QUICK START GUIDE

When the image is dark or bright, you can use the camera to set the automatic mode or manual mode in the

professional options.

Manual mode: You can adjust the brightness of the screen by adjusting the shutter speed, ISO sensitivity, and

MODE

Attention:

1) When video recording, it is not possible to switch the Auto mode and Manual mode; in the Auto mode,the

exposure compensation(EV) can be adjusted only; in the Manual mode, the sensitivity(ISO)value and the

exposure compensation(EV) can be adjusted, and the shutter speed(Expose)value cannot be adjusted.

2) In Manual mode, when the shutter speed(Expose)value and the sensitivity(ISO)value are increased in dark

scenes, the image screen becomes brighter. If the camera lens is facing a brighter light, the screen is often

burst, you need to adjust the shutter speed(Expose) value or the sensitivity(ISO) value to readjust the image

brightness; when the picture is manually adjusted in a brighter scene, when the camera lens is aimed at a

darker place, the shutter value speed(Expose) or the sensitivity(ISO) value must be adjusted manually to

adjust the picture.

3) The factory default is stored in the Micro SD card, and the video can also be stored on the remote control

(change the path: in the APP main interface → → → Video location→local).

The down-view optical flow positioning system uses optical flow sensors to detect the ground below the aircraft to

determine the current height of the aircraft (the height can only be set if the flight height is less than 3 meters).
