Important Operating Considerations for Safety

Place the projector in a horizontal position no greater than 15 degrees off axis.

Locate the projector in a well-ventilated area without any obstructions to intake or exhaust vents.

Do not place the projector on a tablecloth or other soft covering that may block the vents.

Locate the projector at least 4' (1.2 m) away from any heating or cooling vents.

Use only Knoll-approved ceiling mounts.

Use only the power cord provided. A surge-protected power strip is recommended.

Refer to this manual for proper startup and shutdown procedures.

In the unlikely event of the lamp rupturing, discard any edible items placed in the surrounding area and thoroughly clean the area along all sides of the projector.

Wash hands after cleaning the area and handling the ruptured lamp. This product has a lamp, which contains a very small amount of mercury. Dispose of it as required by local, state or federal ordinances and regulations. For more information see www.eiae.org.

Follow these instructions to help ensure image quality and lamp life over the life of the projector. Failure to follow these instructions may affect the warranty. For complete details of the warranty, see the Warranty section at the end of this User's Guide.
