2, hoisting and use Because most projectors have a screen inversion function, this feature allows the projector to be hoisted at the top of the house. For projectors used for indoor ceiling hoisting, the following points should be specially noted: Calculate the distance between the projector and the screen (determined by the screen size); the edge of the wall hanging on the screen should be attached to the projector lens At the same horizontal line; the center point of the projector lens is on the same vertical line as the center point of the projection screen; select the appropriate mounting hanger; install the fixing screws and bolts in place; adjust the trapezoid of the projection screen after installation; after each use , to ensure that the power is turned off.
