NOTE: The projector has an internal temperature sen-
sor. The sensor controls the speed of the fan to keep
constant temperature in the inside.
When the internal temperature rises, the built-in fan au-
tomatically runs at a high speed (high-speed mode).
During this time, the sound of exhaust may be heard.
This is not a malfunction. When the projector orienta-
tion is set to Rear Ceiling or Front Ceiling, the fan is
automatically fixed at the high-speed mode.
(not adjustable)
Rear Foot
To fine-adjust the height of the rear foot, remove
the spacer and rotate the rear foot to the desired
height.
