Folded OpticsIn rear-screen applications where space behind the projector is limited, a mirror may be
used to fold the optical path, as shown in
Figure 3-6. The position of the projector and
mirror must be accurately set. If you are considering this type of installation, contact your
dealer for assistance.

Other ConsiderationsOther considerations and tips that can help improve your installation:
• Keep the ambient temperature constant and below 35°C (95°F). Keep the projector
away from heating and/or air conditioning vents. Changes in temperature may cause
drifts in the projector circuitry, which may affect performance.
• Keep the projector away from devices that radiate electromagnetic energy such as
motors and transformers. Common sources of these include slide projectors,
speakers, power amplifiers and elevators.

Mounting the LS-7
There are several methods for mounting the projector. Depending on your chosen
installation, one method may be more suitable than another.
Floor Mounting (Upright)In typical front and rear screen installations, the projector can be mounted to a secure and
level surface such as a table or cart. Carts are useful when moving a projector during a
presentation or from site to site. If possible, lock the wheels when it’s in position to prevent
it from being moved during a presentation.
Ceiling Mounting
(Inverted)
For fixed installations, and for those that want the projector out of sight or have a limited
space for projector and audience, you can invert the LS-7 and suspend it from the ceiling
using a specially-designed ceiling mount fixture.
Adjusting the Projection
Angle
If the screen is significantly higher or lower than the projector, you can also tilt the
projector at a slight angle. In a ceiling installation, you do this by adjusting the ceiling
mount. For a floor installation, turn the adjustable feet at the bottom of the projector to
adjust the projection angle.
If you do this, you may need to vertically shift the image to compensate. For detailed
instructions, refer to
Lens Adjustments on page 27.
Screen
Mirror
For ceiling installations, use Runco-approved mounting hardware
and M4 screws with a maximum screw depth of 10
mm (0.39 inch).
Install the mount kit according to the instructions provided with it.
