The boresight extensions rods must be installed before installing the ultra short throw lens.
Initially adjusting the boresight screws
Before installing the ultra short throw lens, Christie recommends initially adjusting the boresight. Once
the lens is installed, the adjustment range is limited.
1. Confirm the boresight screws are in their initial position with the blue marks aligned as shown.
2. If the boresight screws are not in their initial position, turn the screws counterclockwise until
they stop and then turn the screws clockwise until the blue marks are aligned as shown above.
3. Adjust the boresight to the recommended ranges according to the projector orientation.
