Precautions for projector installation work
When installing the projector without using the adjustable feet, insert metal spacers (10 mm to 20 mm)
between the projector base and the installation surface to ensure adequate airflow. Furthermore, use the screw
holes (shown in the figure) for ceiling mounting to fix the projector in place. (Screw diameter: M6, set inside
screw length: 8 mm maximum)
Note that if the cabinet is touching the installation surface when used, it may take a while until the images
stabilize after the power is turned on.
