• Keep this user guide in a safe place for later reference.
• Read all warnings and follow all instructions.
• Allow at least 20" (50 cm) clearance around the projector to ensure proper
ventilation.
• Place the projector in a well-ventilated area. Do not place anything on the
projector that prevents heat dissipation.
• Do not place the projector on an uneven or unstable surface. The projector may
fall over, causing personal injury or projector malfunction.
• Do not look straight at the projector lens during operation. The intense light
beam may damage your eyes.
• Always open the lens shutter or remove the lens cap when the projector lamp is
on.
• Do not block the projection lens with any objects when the projector is under
operation as this could cause objects to become heated and deformed or even
cause a fire.
• The lamp becomes extremely hot during operation. Allow the projector to
cool for approximately 45 minutes prior to removing the lamp assembly for
replacement.
• Do not use lamps beyond the rated lamp life. Excessive use of lamps beyond the
rated life could cause them to break on rare occasions.
• Never replace the lamp assembly or any electronic component unless the
projector is unplugged.
• Do not attempt to disassemble the projector. There are dangerous high voltages
inside which may cause death if you should come into contact with live parts.
• When moving the projector, be careful not to drop or bump the projector on
anything.
• Do not place any heavy objects on the projector or connection cables.
• Do not stand the projector on end vertically. Doing so may cause the projector to
fall over, causing personal injury or projector malfunction.
• Avoid exposing the projector to direct sunlight or other sources of sustained
heat. Do not install near any heat sources such as radiators, heat registers,
stoves, or other devices (including amplifiers) that may increase the temperature
of the projector to dangerous levels.
