When the ACS module has been replaced and Default settings have been loaded, the following procedure
should be used to adjust the convergence. Otherwise use the Cursor Up-Down and Right-Left buttons to
Navigate to the area to be adjusted. Press the Menu button to adjust then use the Cursor buttons to move the
Green cross onto the Template. The adjustment of the cross has two step sizes, large and small. Press the
Menu button to toggle between the two. After a point has been adjusted, press the Index button to return to
Navigate. When Default settings have been loaded, the leftmost line that is not visible should be adjusted first.
Adjust the Vertical line 0 while observing line 1 to make line 1 parallel with the left edge of the screen. The
adjustment should only be made in small steps. Do not adjust any one point more than 1/4 the distance of one
grid. After the left most line is adjusted, start at the center left of the screen and work to the right, aligning the
Horizontal line. 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.
When the Red to Green is complete, select the Blue to Green using the same alignment method. Each time
data is stored, the Intellisense circuit will recalculate the position of the four sensors in the set.
Repeat the adjustment for each of the remaining modes.
