Aligning The Image With Lens Zoom And Focus - Christie Boxer 30 Installation And Setup Manual

2. Open the Service door on the side of the projector.
3. Pull out the red and green convergence adjustment knobs.
4. Use the Convergence test pattern to assist with adjusting the red and green horizontal and
vertical lines.
• Vertical convergence and rotation is done by adjusting two knobs. Christie recommends
rotating a single knob a maximum of a quarter rotation before adjusting the second
knob a quarter rotation. For example, if using one hand, turn the left knob a quarter
rotation and then the right knob a quarter rotation, and so on. Adjusting a single knob
for vertical or rotational adjustment to an extreme before adjusting the second knob
may result in the convergence mechanism binding.
5. When complete, push in the red and green convergence adjustment knobs to disengage the
knobs.
