W
ARNING
:
Never start up the projector without light integration rod installed.
About the alignment
The position of the light integration rod into the light pipe has to be aligned for 2 reasons:
• Focusing of the light spot
• Framing the DMD’s on the light spot
For the alignment, a purity pattern is required. A suchlike pattern is available in the projector installation menu, sub item “Internal
patterns”.
