SAFETY The lightning flash 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 sufficient 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 coffee table, sofa, bed, etc. Do not put the projector in an enclosure such as a book case or a cabinet that restricts air flow. ‡‡ To reduce the risk of fire 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 amplifiers 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 fire 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 field. ±± In direct sunlight. ‡‡ Do not use the projector in places where flammable 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 fire. ‡‡ 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 my melt, cause burns or start a fire. ‡‡ 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.
