Safety Precauons
Please read the following Safety Precauons before you start using the projector.
• Keep this user guide in a safe place for later reference.
• Read all warnings and follow all instrucons.
• Allow at least 20“ (50 cm) clearance around the projector to ensure proper
venlaon.
• Place the projector in a well-venlated area. Do not place anything on the
projector that prevents heat dissipaon.
• Do not place the projector on an uneven or unstable surface. The projector may
fall over, causing personal injury or projector malfuncon.
• Do not look straight at the projector lens during operaon. The intense light
beam may damage your eyes.
• Always open the lens shuer or remove the lens cap when the projector lamp is
on.
• Do not block the projecon lens with any objects when the projector is under
operaon as this could cause objects to become heated and deformed or even
cause a re.
• The lamp becomes extremely hot during operaon. 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 aempt 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 connecon cables.
• Do not stand the projector on end vercally. Doing so may cause the projector to
fall over, causing personal injury or projector malfuncon.
• 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 ampliers) that may increase the temperature
of the projector to dangerous levels.

4
• 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 operaon, you may sense some heated air and odor
from its venlaon grill. It is a normal operaon and not a defect.
• Do not aempt 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 t into
your outlet, obtain an adapter and do not aempt to force the plug into the
outlet.
• When connecng 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, parcularly 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 uctuate
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 o and call your dealer or ViewSonic®. It is dangerous to connue
using the projector.
• Use only aachments/accessories specied by the manufacturer.
• Disconnect the power cord from the AC outlet if the projector is not being used
for a long period of me.
• Refer all servicing to qualied service personnel.
CAUTION: Possibly hazardous opcal radiaon is emied from this product. As
with any bright light source, do not stare into the beam, RG2 IEC 62471-
5:2015.

Safety Precautions - Ceiling Mounting
Please read the following Safety Precautions before you start using the projector.
If you intend to mount the projector on the ceiling, it is strongly recommended
that you use a proper fitting projector ceiling mount kit and that you ensure it is
securely and safely installed.
If you use an inappropriate projector ceiling mount kit, there is a safety risk that the
projector may fall from the ceiling due to an improper attachment through the use
of the wrong gauge or length screws.

NOTE: There is 3% tolerance among these numbers due to optical component
variations. It is recommended that if you intend to permanently install the
projector, you should physically test the projection size and distance using
the actual projector in situ before you permanently install it, so as to make
allowance for this projector’s optical characteristics. This will help you
determine the exact mounting position so that it best suits your installation
location.

17
Mounting the Projector
NOTE: If you buy a third-party mount, please use the correct screw size. Screw size
can vary depending on the thickness of the mounting plate.
