INSTALLATION SET-UP INSTRUCTION
Ceiling Mount Projection Distance and Screen Size or XG135LC/XG110LC
• Install in such a way that the projector and screen are positioned in the proper direction and at the proper angle. If not, the projector's
performance will be affected and its reliability will decrease. Be sure to position the projector properly.
The manufacturer will not be held responsible for any problems occurring when the projector is not installed in the proper position.
The following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of
installation
NOTE:
• For screens 150 inches (3810mm) or larger (in the diagonal direction), set so that the distance between the surface of
installation of the mounting A and the ceiling is E.
• Set the projection distance based on the width of the screen.
• If the figures on the table do not match the figures in the formulae, use the figures on the table.
• For screen sizes of 60 to 300 inches not indicated on the table, use the following proportional formulae:
