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 suf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 stare into the beam, RG2.
As with any bright source, do not stare into the direct beam, RG2 IEC 62471-5:2015.
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 coffee 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 5°C ~ 40°C (ii) Relative humidity is 10% ~ 85%
± In areas susceptible to excessive dust and dirt. ± Near any appliance generating a strong magnetic eld. ± In direct sunlight.
Do not use the projector in places where ammable gases or explosives gases may be present in the
atmosphere. The lamp inside the projector becomes very hot during operation and the gases may ignite and result in a re.
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.
4
± 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 could melt, cause burns or start a re.
English
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 appropriate 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. When replacing the lamp, please allow the unit to cool down. This projector will detect the life of the lamp itself. Please be sure to change the lamp when it shows
warning messages.
Reset the "Lamp Reset" function from the on-screen display "Setup lamp settings" menu after
replacing the lamp module.
When switching the projector off, please ensure the cooling cycle has been completed before
disconnecting power. Allow 90 seconds for the projector to cool down.
When the lamp is approaching to the end of its life time, the message "Lamp life exceeded." will show
on the screen. Please contact your local reseller or service center to change the lamp as soon as possible.
Turn off 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.
Note: When the lamp reaches the end of its life, the projector will not turn back on until the lamp module has been
replaced.
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 affect the quality of the projector performance.
Please follow the correct projector orientation installation as non standard installation may affect the
projector performance.
Use a power strip and or surge protector. As power outages and brown-outs can KILL devices.

Cleaning the Lens

Before cleaning the lens, be sure to turn off the projector and unplug the power cord to allow it to
completely cool down.
Use a compressed air tank to remove the dust. Use a special cloth for cleaning lens and gently wipe the lens. Do not touch the lens with your ngers. Do not use alkaline/acid detergents or volatile solvents such as alcohol for cleaning lens. If the lens is
damaged due to the cleaning process, it is not covered by the warranty.
Warning: Do not use a spray containing ammable gases to remove dust or dirt from the lens. This may cause a re due to excessive heat inside the projector.
Warning: Do not clean the lens if the projector is warming up as this may cause the lens’ surface lm to peel off.
Warning: Do not wipe or tap the lens with a hard object.
