Usage Guidelines

•Do not look directly into the projection lens when the lamp is turned on. The bright light may harm your eyes.

•Do not block the grills on the projector. Restricting the air flow can cause it to overheat and turn off. If this happens, you must wait a minute before attempting to turn it back on.

•Handle the projector as you would any product with glass components. Be especially careful not to drop it.

•Avoid leaving the projector in direct sunlight or extreme cold for extended periods of time. If this happens, allow it to reach room temperature before use.

•Transport the projector in a vendor-approved hard or soft case. Part numbers for these cases are listed on page 43.
