Safety Precauons
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 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 use if the projector is lted at an angle of more than 10° degrees le or
right, nor at an angle of more than 15° degrees forwards or backwards.
• Do not look straight at the projector lens during operaon. The intense light
beam may damage your eyes.
• 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.
• 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.
• 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.

4
• 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 optical radiation is emitted from this product. As
with any bright light source, do not stare into the beam, RG2 IEC 62471-
5:2015

Remote Control Effective Range
To ensure proper function of the remote control
follow the steps below:
1. The remote control must be held at an angle
within 30° perpendicular to the projector’s IR
remote control sensor(s).
2. The distance between the remote control and
the sensor(s) should not exceed 8 m (26 ft.)
NOTE: Refer to the illustration for the location of
the infrared (IR) remote control sensor(s).
Approx. 30°
Replacing the Remote Control Batteries
1. Remove the battery cover from the rear of the remote control by pressing the
finger grip and sliding it down.
2. Remove any existing batteries (if necessary) and install two AAA batteries.
NOTE: Observe the battery’s polarities as indicated.
3. Replace the battery cover by aligning it with the base and pushing it back into
position.
NOTE:
• Avoid leaving the remote control and batteries in excessive heat or a humid
environment.
• Replace only with the same or equivalent type recommended by the battery
manufacturer.
• Dispose of the used batteries according to the manufacturer’s instructions and
local environment regulations for your region.
• If the batteries are drained or if you will not be using the remote control for an
extended period of time, remove the batteries to avoid damage to the remote
control.
