6. Click "OK" (15S countdown ends, select OK)

After choosing to enter the advanced keystone correction settings, wait for the pop-up window to prompt the countdown to end in 15 seconds, and select OK to enter the smart calibration page:

7. Follow the prompts to perform trapezoidal calibration 

After entering the calibration interface (as shown in the figure below), check the calibration environment according to the page prompts and the following requirements:

A. Place the machine exactly 1.5 meters away from the projection surface (the straight-line distance from the projection surface to the optical lens), and ensure that the machine is vertical to the projection surface;
B. Use the focus button on the remote control to adjust the projection display to the clearest state;
C. Use a spirit level to measure and ensure that the machine is on a level table without tilt;
D. Under the above conditions, use a tape measure to measure the projection display area, and the left and right sides are roughly equal. If there is a difference in the left and right sides, you can slightly move the machine optical machine left and right in the horizontal direction to make the left and right sides of the optical machine display roughly equal;
These steps are relatively complicated, and the trapezoidal correction function of the device will work well after completion. [If there is no tool, you can roughly judge that they are equal]

8. Calibration successful

A. After confirming the position adjustment of the projector, press the OK button on the remote control or the fuselage to start calibration;
B. Wait for the calibration progress bar below to reach 100%, and the prompt "Camera OK Gsensor OK" below means the calibration is successful.
C. Exit the page and turn on automatic keystone correction. The relevant function switches can be used normally.
