Touch Unit Safety Instructions
The Touch Unit enables finger touch interactivity with your projector. Do not connect it to any other
projectors or devices.
Follow these precautions when using the Touch Unit and finger touch interactivity:
• Children using finger touch interactivity should always be accompanied by an adult.
• Never disassemble or modify the Touch Unit. Never open any cases on the projector or Touch Unit.
Electrical voltages inside the projector can cause severe injury.
• Do not look into the laser diffusion ports on the back of the Touch Unit. The laser can damage your
eyes. Extra care should be taken when children are present.
• Do not allow the laser light from the Touch Unit to pass through or be reflected by any optical devices,
such as a magnifying glass or mirror. This could cause personal injury or fire.
• Do not view the laser light from the Touch Unit using an optical device such as an eye loupe,
magnifying glass, or microscope, especially within 2.75 inches (70 mm) of the laser diffusion ports.
This could damage your eyes.
• Unplug the projector from the electrical outlet and refer all repairs to qualified service personnel if any
problems occur with the Touch Unit. Continued use of the Touch Unit may result in fire or accidents,
and can also damage your eyes.
