X-Y-Z values to stabilize. The motors and sensors will work together to precisely
position the lamp for optimized performance and brightness at the screen, utilizing
filtering to eliminate signs of lamp flicker. Progress status is displayed near the
bottom of the menu. When complete, the lamp alignment is optimized for the current
installation.
NOTES: 1) A 10-minute warm-up is recommended before adjusting LampLOC. 2)
Intensity mode(brightness tracking/LiteLOC) is disabled during a LampLOC
adjustment.

adjust in one direction, then back up when the reading begins decreasing.
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—watch the intensity feedback shown near the top of the menu if preferred.
