Use the “Do Auto” Button for LampLOC

For best results in all installations, align the lamp
by pressing the
DO AUTO
button in the
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

buttons
The individual LampLOC

arrow buttons, each of which moves the lamp in one
direction only, are provided as a reassuring back-up should the
DO AUTO
button fail
or if you feel a manual, operator-assisted lamp optimization will result in more
output. Either measure your results with a light meter at the lens and screen or simply
watch the light output gauge in the
Advanced: Lamp menu. Note that with these
buttons you may attain a slightly higher peak than with the
DO AUTO
button, but the
peak may not be centered on the lamp curve and lamp performance may not be
optimized (whereas the
DO AUTO
button also utilizes filtering to eliminate the effects
of any lamp flicker). In general, use the individual buttons only when you feel it is
unavoidable.
HOW TO ADJUST (IF USING A LIGHT METER):
First obtain peak readings on a light
meter centered in front of the lens, then at the center of the screen. For each button,
continue in one direction, then back up when 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—use the light output gauge in the Advanced: Lamp menu if preferred.
1. Adjust forward/aft (z) until the
brightness reading in front of the
lens is maximized.
2. Adjust left/right (x) and up/down
(y) until the brightness reading in
front of the lens is maximized
3. Re-adjust forward/aft (z) as
necessary.
4. Repeat Steps 1-3 as necessary.
5. Repeat Steps 1-4, but reading at the
screen instead of at the lens.
6. Reset Lamp Power or LiteLOC

if desired.
