3.12.1 Adjust Offset

Project an image with the primary lens only. The optional auxiliary lens mount, if present, can be

mounted, but moved aside by loosening the 4 bolts on the front cover and sliding the assembly out of

the way. From the CDP access the Lens Control>Lens Adjustment menu to adjust horizontal and

vertical offset, as necessary to display a square image on screen with minimal projector aiming error.

Always adjust offset before boresight. NOTES: 1) For best optical performance, minimize keystone

error by using offset more than aiming to the center of the image in off axis installations. 2) Horizontal

and vertical offset can be adjusted via the web user interface, Main>ILS.

3.12.2 Adjust Lens Mount Boresight

When performing these adjustments the goal is to balance the tilt of the lens mount to compensate for

screen to projector tilt, but also to precisely maintain the original factory settings of the lens mount

axial position.

Lens Mount Vertical Boresight

1. It is recommended that top/bottom boresight be completed before horizontal boresight.

NOTE: Typically, horizontal boresight does not require adjustment. It should only be adjusted if a

large horizontal angular offset to the screen is required.

2. Select an appropriate test pattern for boresight adjustments, via the CDP through the Test Patterns

menu. It is recommended to use the DC2K Framing test pattern.

3. Use a 5mm Allen™ key to loosen the setscrew (Figure 3-12, B).

4. Use the 5mm Allen™ to turn the vertical adjust capscrew 1/8 of a turn counter-clockwise. (Figure

3-12, A).

CAUTION

Only adjust vertical boresight 1/8 of a turn or less at one time to maintain

optimal lens performance (i.e. factory setup of absolute lens distance to the

prism). It is critical that each turn of the capscrews is tracked to ensure

adjustments are accurate.
