Safety Warnings and Guidelines

2.6.1 Labels and Markings

• Observe and follow any warnings and instructions marked on the projector.
• The exclamation point within the equilateral triangle indicates related operating/maintenance instructions in
the documentation accompanying the projector.
• The lightning flash and arrowhead symbol within the equilateral triangle indicates non-insulated "dangerous
voltage" within the projector's enclosure that may be of sufficient magnitude to constitute a risk of electric
shock.

2.6.2 General Precautions

Never look directly into the projector lens or at the lamp. The extremely high brightness
can cause permanent eye damage. For protection from ultraviolet radiation, keep all
projector housings intact during operation. Protective safety gear and safety goggles are
recommended when servicing.
FIRE HAZARD! Keep hands, clothes, and all combustible material away from the
concentrated light beam of the lamp.
• Position all cables where they cannot contact hot surfaces or be pulled or tripped over.
• The American Conference of Governmental Industrial Hygienists (ACGIH) recommends
occupational UV exposure for an 8-hour day to be less than 0.1 microwatts per square
centimeters of effective UV radiation. An evaluation of your workplace is advised to assure
employees are not exposed to cumulative radiation levels exceeding the government
guidelines for your area. Be aware that some medications are known to increase sensitivity
to UV radiation.
This projector must be operated in an environment that meets the operating range specification, as listed in
Section 9 Specifications.
