Safety Precautions

Please read the following Safety Precautions before you start using the projector.

• 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 use if the projector is tilted at an angle of more than 10° degrees left or right, nor at an angle of more than 15° degrees forwards or backwards.
• Do not look straight at the projector lens during operation. The intense light beam may damage your eyes.
• 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.
• 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.
• Do not place liquids near or on the projector. Liquids spilled into the projector may cause it to fail. If the projector does become wet, disconnect it from the power supply and call your local service center to have the projector serviced.
• When the projector is under operation, you may sense some heated air and odor from its ventilation grill. It is a normal operation and not a defect.
• Do not attempt to circumvent the safety provisions of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide and third blade are  provided for your safety. If the plug does not fit into your outlet, obtain an adapter and do not attempt to force the plug into the outlet.
• When connecting to a power outlet, DO NOT remove the grounding prong. Please ensure grounding prongs are NEVER REMOVED.
• Protect the power cord from being treaded upon or pinched, particularly at the plug, and at the point where it emerges from the projector.
• In some countries, the voltage is NOT stable. This projector is designed to operate safely within a voltage between 100 to 240 volts AC, but could fail if power cuts or surges of ±10 volts occur. In areas where voltage may fluctuate or cut out, it is  recommended that you connect your projector through a power stabilizer, surge protector, or uninterruptable power supply (UPS).
• If smoke, an abnormal noise, or a strange odor is present, immediately switch the projector off and call your dealer or ViewSonic®. It is dangerous to continue using the projector.
• Use only attachments/accessories specified by the manufacturer.
• Disconnect the power cord from the AC outlet if the projector is not being used for a long period of time.
• Refer all servicing to qualified service personnel.

• If the lens is still not clean, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently wipe the surface.

CAUTION: Never rub the lens with abrasive materials.
Cleaning the Case

• Use a soft, lint-free, dry cloth to remove dirt or dust.
• If the case is still not clean, apply a small amount of non-ammonia, non-alcohol based, mild non-abrasive detergent onto a clean, soft, lint-free cloth, then wipe the surface.
