Horizontal adjustments are controlled by adjusting knob 3.

Vertical convergence and rotation are controlled by adjusting knobs 1 and 2. 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.

For the best stability, Christie recommends setting convergence while rotating the knobs in a

clockwise direction. This may require first adjusting convergence by turning the knobs counter-

clockwise and finalizing the convergence with a clockwise approach. This applies to all knobs.

8. When complete, push in all the convergence adjustment knobs to disengage them.

If the colors at the corners of the screen require further correction, see Electronically adjusting

convergence.
