Installing Small Iris
If it is requested by the customer to reduce the projector's lamp luminance, because it is too
bright even when set to the minimum level, you may reduce it as follows. This operation will
also improve the contrast ratio.
Preparatory operation:
• Make sure that the main power switch of the customer's projector is turned off.
• Get the supplied small iris ready. (Included in the standard set of accessories)
