Setting Up The Projector - Christie DHD630-GS Installation Manual

Setting up the projector

Follow these steps to mark the target screen and set up the projector.
1. Make sure the projector is position perpendicular to the projection wall.
2. Mark the size and center of the projection target screen.
Christie recommends the projection image size is at least 25.4 cm (10 inches) larger than the
target screen size.
3. Based on the projection screen size, calculate the setup dimension.
See the Lens specification table (on page 17).
4. Make sure the variation of the B value and the value in the Lens specification table are within
+/-1cm (+/-0.4 inches).
5. Make sure the variation of the M value and the value in the Lens specification are within
+/-1cm (+/-0.4 inches).
