Failure to engage the safety lock could cause the
projectors to separate and result in injury or death.
Leg Nuts
'
Before hoisting, firmly tighten the nuts on the (2) rear stacking legs (Figure 2.14). Or,
if you are ready to align the projectors to one another, leave these nuts slightly loose
until after the alignment.
Repeat STEPS 1–9 for a third projector.
Stacked projectors must be correctly aligned to one another so that the resulting
'
display is optimized and as sharp as possible. If you are also hoisting the stack, hoist
the stack into place first, then align. Lock all stacking hardware into place to maintain
your alignment.
Before You Begin
Always align to the fixed projector. In floor-mount or table-mount (i.e., non-
hoisted) stacks, you will align to the bottom projector as shown in drawings
below. In hoisted stacks, align to the top projector.
Leg nuts must be loosened before alignment; otherwise the stacking mounts will
not turn and allow movement of the projector.
Position the first image (fixed projector)
Position the fixed projector's image as desired and align the other image(s) to it as
described below.
Display the grid test pattern
To distinguish each image, enable "Red" for one display and "Green" for the other.
See 3.3, Using the Keypads if you need help enabling colors.
Adjust zoom and focus
Minimize each projector's zoom and images are in focus.
Try aligning the two grid patterns
Adjust zoom and offset on the top projector to precisely move its test pattern display
on to the bottom test pattern. When properly aligned, all red/green grid lines in the
combined image will turn yellow.
•
If all lines are well aligned, skip to STEP 7 to lock all stacking mounts.
•
If alignment needs improvement, proceed with the next step.
WARNING
WARNING
Never stack more than 3 projectors.
IMPORTANT
Make sure the stacking legs have been extended
by at least 1 inch, and are slightly loosened.
