direct or aim the lens mount toward the bottom of the screen

Adjusting the fold mirror

The fold mirror is used to bend the optical path.
If a corner or edge of an image is missing, the fold mirror might be misaligned with the optical system
and needs to be re-adjusted.

• UV EXPOSURE! Protective UV safety glasses with side shields and Christie approved protective
safety clothing must be worn when performing optical adjustments or servicing the product.
