dim normally. Either reduce your “Intensity” setting or replace the lamp.
Do not lower the “Intensity” so much that the corresponding “Power” value reaches its
minimum — the intensity setting will be inaccurate and cannot be maintained.
Aperture Control: The optical aperture inside the projector controls the diameter of the
light beam passing through the system. With a fully open aperture (slidebar default of “0”),
the maximum amount of light passes through for maximum brightness in your images.
Increase the slidebar setting to reduce the aperture diameter and maximize contrast ratio
instead.
Lamp History (read-only): Lamp History shows the lamps most recently installed and
recorded in the projector. The Lamp History automatically updates whenever you record a
new lamp serial number; the new lamp is added to the end of the list.
Change Lamp: Select Change Lamp from the Lamp menu to record the serial number for a
newly-installed lamp. For detailed lamp replacement instructions, refer to
