Other 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.

There are several methods for mounting the projector. Depending on your chosen installation, one method may be more suitable than another.

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.

For fixed installations, and for those that want the projector out of sight or have a limited	Ceiling Mounting
space for projector and audience, you can invert the LS-7 and suspend it from the ceiling	(Inverted)
using a specially-designed ceiling mount fixture.

For ceiling installations, use Runco-approved mounting hardware

Note 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.

If the screen is significantly higher or lower than the projector, you can also tilt the	Adjusting the Projection
projector at a slight angle. In a ceiling installation, you do this by adjusting the ceiling	Angle
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.
