Positioning the projector
Position the projector in relation to the screen.
For information on positioning the projector in a rigging frame, refer to the Assembling the Precision 1
Rigging Frame (P/N: 020-102719-XX) or Assembling the Boxer Rigging Frame (P/N: 020-102018-XX)
instruction sheet.
1. Position the projector with the lens perpendicular to the screen.
Keep the projector lens as perpendicular to the screen as possible, even if significantly above
the screen center. When a particularly short throw distance combines with a wide screen, you
may have to forfeit some aim and stay more perpendicular to the screen. In such cases, some
lens offset can reduce the keystone distortion.
2. Center the projector with the screen.
Leveling the projector
Use the projector feet to level the projector.
1. To adjust the vertical position of the projector, extend or retract the adjustable feet on the
bottom of the projector using the adjustable knobs on the feet.
Christie recommends adjusting the feet from the side or rear of the projector and not the front
to avoid exposure to the output light.
The projector feet are removable and can be moved to the top of the projector to run in an
inverted orientation.
2. Once the required adjustment is made, using a wrench, tighten the lock nut against the
bottom of the projector.
Installing the projector lens
Only use lenses designed for Mirage 304K projectors. Installing a lens not designed for Mirage 304K,
results in a warning that the lens is not present.
1. Turn off the lasers.
2. Remove the lens caps from the lens.
The packaging tape is required to ensure safe shipment of the projection lens to restrain the
zoom ring from rotating during shipping.
