Setup
1. Placement and Power Connection:
Place the projector on a stable, flat surface. Ensure adequate ventilation around the device. Connect the power cable to the projector's power input and then to a power outlet.

3. Initial Focus and Keystone Correction:
After powering on, use the remote control's F+ or F- buttons to adjust the electric focus until the image is clear. If the image appears trapezoidal, use the manual keystone correction feature to square the image. This feature helps correct image distortion when the projector is not perfectly perpendicular to the screen.
