Precautions for Installation (Cont.)
■Observe the following points when installing the projector by hanging it from the ceiling
•To prevent falling or overturning, it is recommended that the projector be fixed to its stand with bolts.
•When mounting the projector to the ceiling, first install a special shelf and then set the projector on it securely. For safety
and maintenance purposes, a suitable facility is necessary to easily lift and lower the projector from the shelf for mainte-
nance access.

■Light energy decreases as it passes a glass. So, no more than one glass should be used in the projecting room.
■Avoid using panes of glass as much as possible.
■Pay attention to the angle of the glass and the installed angle of the projector so that the light emitted from the
projector does not come back into the lens after reflection.
