4.12 Image Adjustments

Use the following guidelines for safely servicing Christie equipment that needs to remain energized (live)
during a service procedure.
Only Christie accredited technicians who are knowledgeable about the hazards associated with hazardous
voltage, ultraviolet exposure, and high temperatures are authorized to assemble, install, and service Christie
equipment.
To make sure you remain safe when servicing energized (live) Christie equipment:
• Locate the main AC power shut off prior to servicing the equipment. This will allow you to turn the power
off quickly in an emergency.
• Disconnect the projector from the communication and management network so it cannot receive commands
to turn the lamp on, open the douser, and move the lens.
• Familiarize yourself with all potential safety hazards prior to servicing the equipment. This includes, but is
not limited to, the location and accessibility of hazardous voltages.
• Read and understand all written procedures prior to commencing a service procedure.
• Understand and follow all local safety codes and requirements when servicing energized (live) equipment.
• Perform equipment service in a location free of obstructions and other hazards. For example, you must have
an unobstructed view of the area being serviced.
• Wear personal protective equipment (PPE) clothing appropriate to the service you are performing. This
includes, but is not limited to, protective (electrically insulated) footwear, safety glasses, and gloves rated for
the working voltage of the equipment you are servicing.
