WARNING! Read and observe these precautions and all others in this manual to reduce the risk of

injury and equipment damage. Do not look directly into the lens when the lamp is on. Do not expose the
projector to rain or moisture, and do not use it near water. Keep paper, plastic, and combustible material
at least 2 ft (0.5 m) away from the projector lens and exhaust vents. Do not allow liquid, food, or small
objects to get inside the projector. If material gets inside the projector, contact HP for assistance. Do
not put anything on top of the projector. Do not place any liquids where they might spill on the projector.
Do not block any vents on the projector. Do not place the projector near any source of heat, such as a
radiator or amplifier. Use only an approved power cord rated for the voltage and current marked on the
product label. Do not overload any outlet or extension cord. Do not circumvent the grounding prong on
the power cord. Route all cables so they are not located where people can step on them or trip on them.
Place the projector flat on its base on a sturdy surface. Do not stand the projector on its front surface.
Do not touch the lens with your fingers. Use a soft, dry cloth to clean the projector case. Do not open
the projector. If the projector is damaged in any way, contact HP for assistance.

CAUTION: To prevent damage to the projector or its components during use, observe these

precautions:

Avoid using the projector near appliances that generate heat.

Avoid exposing the projector to excessive dust. Dust may cause the projector to fail and automatically
shut down.

Be sure that the projector is placed in a well-ventilated area.

Avoid blocking the projector's vents and openings.

Do not operate the projector over 47.5°C temperature. The projector operates well within this
temperature range.
