Adjusting boresight
The boresight adjustment turns the lens holder to remove the tilt between the lens and DMD to
make the image clear, crisp, and sharp. To perform boresight adjustment, use an M4 Allen key to
adjust the three boresight set screws on the lens holder.
To perform boresight adjustment, complete the following steps:
1. Project a focus test pattern.
2. To optimize the focus of position 1 on the screen, press the FOCUS or key.
3. Once position 1 is in focus, check position 2. If position 2 is not in focus, use the FOCUS or
key to bring position 2 into focus on the screen.
• If pressing the FOCUS key results in position 2 coming into focus, turn the set screw A
clockwise.
