made in small steps. Do not adjust any one point more than 1/4 the distance of one grid in each pass.
After the left most line is adjusted, start at the center left of the screen and work to the right, aligning the
Horizontal lines. When adjusting the Horizontal lines, best results are obtained when working from left to
right. After the Center line is adjusted, go to the next line down until all of the lines have been adjusted,
then work from the center up to adjust the Horizontal lines. Using the same method, work from center
out to adjust the Vertical lines. At least three passes will be necessary to complete the alignment. Press
the Index button to return to the selection menu.
When the Green geometry is complete, Store the data. Remove the Template from the screen.
Select Red to Green in the selection menu. Using the same method that was used to adjust the
Green Grid to the Template, adjust the Red Grid onto the Green Grid. If the set is a later produc-
tion, select SP RED to center the Red grid onto the Green grid. Exit this mode by pressing the
Menu button. Then select the MP RED to adjust the Red onto the Green using the 35-point adjust-
ment. When this is complete, select the RED TO GREEN to perform the 208-point adjustment.
When the RED TO GREEN is complete, select the BLUE TO GREEN using the same alignment
method as the RED TO GREEN.
Select STORE to save your the alignments after adjusting each color. Each time data is stored; the
Intellisense circuit will recalculate the position of the four sensors in the set. The Epic plus version only
has the Intellisense. Exiting the Convergence Mode without saving will cause the alignments to be lost.
Repeat the adjustment for each of the remaining modes.
