LSM2:
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. Turn the boresight gears counter-clockwise to the end position with the boresight extension
rod.
Ignore the marks, marks are for production requirements only.
2. If the boresight screws are not in their initial position, turn the screws counterclockwise until
they stop .
3. Adjust the boresight to the recommended ranges according to the projector orientation.
