Red on green convergence.
Use the control stick to hightlight Red on
green and press ENTER to display the
Red on green test pattern.
The longest lines are the red lines.
These lines must be converged with
the green lines.
The drawn screws and numbers are
displayed in red.
Follow next steps :
a. Adjust first screws 4, 5 and 6 to
obtain an optimal focus for respec-
tive lines 4, 5 and 6.
Due to interaction, it may be neces-
sary to repeat step a several times.
Follow next steps to converge the red lines with the green lines :
b. Start with screw 2 and adjust for optimal convergence of line 2.
c. Adjust screw 3 for optimal convergence of line 3.
Due to interaction repeat above two steps (b and c) if line 2 and possibly line 3 is
misaligned.
If both lines are correctly converged, continue with screw 4.
Adjust screw 4 until line 4 is correctly converged. It is possible that line 2 and 3 have
to be reconverged. If so, repeat procedure for screw 2 and 3 (step b and c)
If line 2, 3 and 4 are converged, continue with line 1 (screw 1).
When line 1 is converged, check again the convergence of lines 2, 3 and 4. If
necessary repeat the above procedure for the corresponding lines.
