Note
z
The illustrations of projectors in this manual are for informational purposes only and do not
represent a specific projector model. Configurations may vary with the model.
z
Dimension L4 is the distance from the projector rear panel to the screen.
z
Dimension A2 is the distance from the bottom edge of the screen to the bottom of the
adjustable projector legs (with the legs fully screwed in).
Attention
z
Dimension L4 is not the distance from the projector rear panel to a wall, but the distance
from the projector rear panel to the screen. To prevent obstruction of the intake and
exhaust vents, install the projector with a clearance at least 500 mm (19-11/16") from walls
and objects.
When placing the projector in a confined space, a ventilation and/or air conditioning system
is required.
Exhaust heat may accumulate when the ventilation is not sufficient triggering the protection
circuit of the projector.
z
Avoid setting up in places which are subject to sudden temperature changes, such as near
an air conditioner or lighting equipment (studio lamps, etc.).
