projector may simply be poorly placed in relation to the screen. 3) Simultaneously

Mounting
'
For typical front or rear floor mounts, mount the projector on a
secure table or cart. Take care with a mobile cart—avoid
sudden stops, excessive force and uneven surfaces that may
cause the projector and cart combination to overturn.
The table or cart should be reasonably level. Fine adjustments to the projector level
can be made by adjusting the height of the projector legs; refer to 2.7, Leveling for
details.

Special Mounting

Note that projector can be rotated and mounted at any vertical angle—i.e., you can
tilt the face of the projector up or down as much as desired for your installation. The
side-to-side tilt, however, must not exceed 15° (see Figure 2.11). This limit ensures
that the arc lamp in the projector operates properly and safely. Always make sure that
exhaust air from the projector does not vent towards the lens, otherwise you may
detect heat waves in your projected image.
You must use the proper ceiling mount fixture or stacking kit for your projector. For
more information, contact your dealer.
Folded Optics
'
In rear screen applications where space behind
the projector is limited, a mirror may be used
to fold the optical path. See right. The position
of the projector and mirror must be accurately
set—if considering this type of installation, call
your dealer for assistance.
