Use the "Do Auto" Button for LampLOC
For best results in all installations, align the lamp
by pressing the
DO AUTO
Advanced: Lamp menu. The motors and sensors
in the projector will work together to precisely
position the lamp for optimized performance and
brightness, utilizing filtering to eliminate signs
of lamp flicker. Once aligned, this LampLOC
setting can be considered fairly stable for the life
of the lamp.
When to use the individual LampLOC

NOTES: 1) Display a 100% white internal test pattern. 2) Use a tripod to center the
light meter with the lens. Distance from the lens does not matter. You may need an
attenuator, or wish to construct an internal foil aperture first. 3) This is an optional
procedure—use the light output gauge in the Advanced: Lamp menu if preferred.
1. Adjust forward/aft (z) until the

necessary.
