Turning Off The Projector; Aligning The Image; Adjusting Offset - Christie Roadie D4K40-RGB Installation And Setup Manual

Turning off the projector

When powering off in preparation for inspection or maintenance, always disconnect from AC.
1. To turn the light source off using the projector keypad, press and hold the
hear a beep.
To turn off the light source using the remote, press and hold the OFF button until you hear a
beep.
When powering off the projector, allow the projector to complete its cool down cycle. Do not
immediately unplug the projector if this can be avoided.
2. To turn off power to the projector, disconnect from AC power.
3. To turn off power to the projector, turn off the projector breaker switch and disconnect from AC
power.

Aligning the image

Only perform image alignment after the projector is fully assembled and powered up in its final
location.
Basic image alignment ensures the image reflected from the DMDs is parallel and well-centered with
the lens and screen. This initial optical alignment is the foundation for optimizing images on the screen
and must be completed before final boresight adjustments. Before beginning, make sure the projector
is properly positioned in relation to the screen.
1. Make sure the projector is positioned in the throw distance range for the particular lens.
2. Display a test pattern.
3. Do a quick preliminary focus and (if available) zoom adjustment with the primary lens.
Do not worry about consistency across the image at this point, just center focus. It is good
practice to have zoom adjustment and focus adjustment in the center of its range.
4. Holding a piece of paper at the lens surface, adjust offsets as necessary until the image is
centered within the lens perimeter. A full black field works best for this.
5. If the projector is mounted off center to the screen axis, offset the lens as much as required.
Aim the projector over slightly towards the center of the screen, but use caution when doing
so, as too much tilt causes excessive keystone distortion.
6. With a framing pattern on screen, double-check projector leveling so the top edge of the image
is parallel to the top edge of the screen.

Adjusting offset

Adjust the offset to align the image on the screen. Always adjust offset before adjusting boresight.
For the best optical performance and minimal keystone, use offsets instead of aiming at the center of
the image, in off-axis installations. Avoid extreme tilts or offsets. Corner vignettes on a white test
pattern indicate extreme offset that should be avoided using mechanical alignment.
1. Project an image with the primary lens.
2. Select a framing test pattern.
3. Select LENS OFFSET.
You can also select MENU > Configuration > Lens Settings > Lens Offset.
