• The following graphic symbol,, indicating that looking into the projector is prohibited, is displayed on the projector cabinet.
• Do not allow yourself to look into the projector beam at any distance from the projector. An adult should supervise the children to prevent exposure risks.
• Check that there is no one looking at the lens when using the remote control for starting the projector.
• Do not look at the projected light using optical devices (binoculars, telescopes, magnifying glasses, reflectors, etc). Doing so could result in vision impairment.
• When performing the lens shift adjustment, make sure that you are behind or beside the projector. Doing so from the front of the projector may cause intense light to enter your eyes, resulting in damage to them.
• [WARNING: MOUNT ABOVE THE HEADS OF CHILDREN.] The use of a ceiling mount is recommended with this product to place it above the eyes of children.
• This projector, which is an RG3 product, is for business use and must be installed in a location where safety is assured.

Features

• DLP Cinema® projector Complies with the strict projection standards defined by the Digital Cinema Initiatives (DCI) industry group in the United States using leading imaging technology. It also supports 3D projection and high frame rates (HFR).
• Employs a long-life laser light source. The projector employs a newly developed laser light source offering excellent reliability and redundancy. Since the laser light source has a long life, this delivers low-cost operation by removing the need for maintenance, such as replacing and adjusting the light module over extended periods of time. Furthermore, it reduces the risk of the light source suddenly shutting off and leaving a black screen.
• Delivers reduced installation space and increased freedom through a more compact and lightweight body The use of a 0.69″ DLP cinema chip together with integration of the light module into the projector main unit both delivers a reduced installation area as well as improving the degree of freedom of installation, such as removing the need to connect to external ventilation ducting and supporting both pedestal-mounted and ceiling-suspended installation. A wide variety of optional lenses (sold separately) is also available for the projector in order to support a wide variety of installation methods (a lens is not mounted when the projector is shipped from the factory).
• Equipped with easy-to-use functions
  1. Lens memory function and light memory function that can be operated with one touch.
     The projector is equipped with a lens memory function that can save the zoom position and shift position of the lens and a light memory function that can save the brightness setting separately for each input signal. This makes it possible to project using preconfigured settings simply by selecting the signal when projecting multiple different input signals, each with a different screen size and brightness settings (Refer to “6-9. Related products list” (page 78) for details on the lenses that support the lens memory function).
  2. Built-in automatic adjustment function that makes the brightness and color of the light source uniform. Degradation of brightness and variations in color that occur as the light source is used for longer periods of time are kept to a minimum (the period over which variations in brightness can be limited varies depending on the brightness setting).
  3. Frequently used titles can be registered in preset buttons. The projector has been equipped with 8 preset buttons that make it easy to selecta registered title (input signal). To this projector, 100 titles at most can be registered (input signal registration). Among the registered titles, any 16 titles can be assigned to the preset buttons.
  4. You can operate and configure the projector via a network from a PC You can operate and configure the projector via a network from a PC by using the separately supplied software Digital Cinema Communicator (DCC) V2.

Advanced Dust Protection

A dust control shield is arranged between each DMD chip of R, G, and B, and the spectroscopic/condenser prism. It prevents dust and dirt in the air, and oily particles in smoke associated with event halls from coming into contact with the face of the DMD and causing operating problems.

• Reduced running costs thanks to the use of metal filters. The filters are made of metal, so they can be used repeatedly and do not have to be replaced when performing periodic cleaning. This not only reduces running costs, but also contributes to preserving the environment since spent filters are not discarded.
