SETUP AND INSTALLATION
Boresight adjustment
Only apply a boresight adjustment in case the overall focus of the projected image is not equally sharp. The
boresight adjustment helps to balance the tilt of the lens mount to sharpen the unfocused sections of the image.
It tilts the lens holder to parallel the lens plane and the DMD plane.
Note:
This boresight adjustment process may cause the other areas of the image to slide out of focus. This is
totally normal.
Required tool
The following tools are required for boresight adjustment:
‡ Allen key, hex 4mm
For A11/A18/A27 lens, the following tools are required:
‡ Boresight extender with red rubber ring
‡ L-shape socket tool
Setting the projector start mode
1. Choose the test pattern of the OSD. Switch to full screen mode.
2. Prepare the test area. Verify that the throw ratio of the installed lens matches the requirements of the
installation area (projection distance and screen size).
3. Check that the lens is correctly installed.

Use the Allen key screwdriver to clockwise or counter-clockwise adjust the three boresight screws.
For A11/A18/A27 lens
