SAFETY
The lightning ash with arrow head within an equilateral triangle is
intended to alert the user to the presence of uninsulated "dangerous
voltage" within the product's enclosure that may be of su󰀩cient
magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert
the user to the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the appliance.
Please follow all warnings, precautions and maintenance as recommended in this user’s guide.
Important Safety Instruction
• Do not block any ventilation openings. To ensure reliable operation of the projector and to protect from
over heating, it is recommended to install the projector in a location that does not block ventilation.
As an example, do not place the projector on a crowded co󰀨ee table, sofa, bed, etc. Do not put the
projector in an enclosure such as a book case or a cabinet that restricts air ow.
• To reduce the risk of re and/or electric shock, do not expose the projector to rain or moisture. Do not
install near heat sources such as radiators, heaters, stoves or any other apparatus such as ampliers
that emits heat.
• Do not let objects or liquids enter the projector. They may touch dangerous voltage points and short
out parts that could result in re or electric shock.
• Do not use under the following conditions:
± In extremely hot, cold or humid environments.
(i) Ensure that the ambient room temperature is within 0°C ~ 40°C
(ii) Relative humidity is up to 80%
± In areas susceptible to excessive dust and dirt.
± Near any appliance generating a strong magnetic eld.
± In direct sunlight.
• Do not use the unit if it has been physically damaged or abused. Physical damage/abuse would be
(but not limited to):
± Unit has been dropped.
± Power supply cord or plug has been damaged.
± Liquid has been spilled on to the projector.
± Projector has been exposed to rain or moisture.
± Something has fallen in the projector or something is loose inside.
• Do not place the projector on an unstable surface. The projector may fall over resulting in injury or the
projector may become damaged.
• Do not block the light coming out of the projector lens when in operation. The light will heat the object
and may melt, cause burns or start a re.
• Please do not open or disassemble the projector as this may cause electric shock.
• Do not attempt to service the unit yourself. Opening or removing covers may expose you to dangerous
voltages or other hazards. Please call Optoma before you send the unit for repair.
• See projector enclosure for safety related markings.
• The unit should only be repaired by authorized service personnel.
• Only use attachments/accessories specied by the manufacturer.
• Do not look into straight into the projector lens during operation. The bright light may harm your eyes.
• This projector will detect the life of the light source itself.

English 5
• When switching the projector o󰀨, please ensure the cooling cycle has been completed before
disconnecting power. Allow 90 seconds for the projector to cool down.
• Turn o󰀨 and unplug the power plug from the AC outlet before cleaning the product.
• Use a soft dry cloth with mild detergent to clean the display housing. Do not use abrasive cleaners,
waxes or solvents to clean the unit.
• Disconnect the power plug from AC outlet if the product is not being used for a long period of time.
• Do not setup the projector in places where it might be subjected to vibration or shock.
• Do not touch the lens with bare hands.
• Remove battery/batteries from remote control before storage. If the battery/batteries are left in the
remote for long periods, they may leak.
• Do not use or store the projector in places where smoke from oil or cigarettes may be present, as it
can adversely a󰀨ect the quality of the projector performance.
• Please follow the correct projector orientation installation as non standard installation may a󰀨ect the
projector performance.
• Use a power strip and or surge protector. As power outages and brown-outs can KILL devices.

• As with any bright source, do not stare into the direct beam, RG2 IEC 62471-5:2015.
• This projector is class 1 laser product of IEC/EN 60825-1:2014 and risk group 2 with the requirements
of IEC 62471-5:2015.
• Supervise children: no staring, and avoid use of optical aids!
• Notice is given to supervise children and to never allow them to stare into the projector beam at any
distance from the projector.
• Notice is given to use caution when using the remote control for starting the projector while in front of
the projection lens.
• Notice is given to the user to avoid the use of optical aids such as binoculars or telescopes inside the
beam.
• When turning on the projector, make sure no one within projection range is looking at the lens.
• Keep any items (magnifying glass etc.) out of the light path of the projector. The light path being
projected from the lens is extensive, therefore any kind of abnormal objects that can redirect light
coming out of the lens, can cause an unpredictable outcome such as a re or injury to the eyes.
• Any operation or adjustment not specically instructed by the user’s guide creates the risk of
hazardous laser radiation exposure.
