    Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projector, it will automatically turn off by operating one of the following protection circuits. Thermal Switch Thermal Switch There is a thermal switch inside the projector to detect the lamp surrounding temperature rising abnormally.
  • Page 6 Circuit Protection POWER indicator The POWER indicator shows the state of the function which protects the projector. Check the state of the POWER indicator to take proper maintenance. The projector is shut down and the POWER indicator is POWER indicator flashing orange.
  • Page 7 Maintenance and cleaning Cleaning the filter The air filter prevents dust from accumulating on the surface of the optical elements inside the projector. Should the air filter become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in a buildup of internal heat and adversely affects the life of the projector.
  • Page 8 Maintenance and cleaning Clean the project lens Unplug the AC power cord before cleaning. Gently wipe the projection lens with a cleaning cloth that contains non-abrasive camera lens cleaner, or use a lens cleaning paper or commercially available air blower to clean the lens.
