H. Convergence Adjustment
Input R+B and R+G signals, make sure convergence within specified (if not 4 pole and 6 pole). A zone =
0.3MM., B zone 0.4MM. (X) < 0.4MM, (Y) < 0.4MM.
NOTE : 1 A area = 230mm (circle)
2 B area = 306 x 230 mm
I. Presetting Modes Adjustment

3. V-SIZE adjust : adjust control key to get V-SIZE = 230 ± 2mm
4. V-CENTER adjust : adjust control key to get center within ±2mm
5. Geometric adjust : adjust control key to get minimize distortion.
6. H-linearity check : check and make sure linearity meet spec.
7. V-linearity check : check and make sure linearity meet spec.
8. Geometric check : check and make sure geometric meet spec.
9. Get into OSD select EE-USER item, press ENTER till OSD disappear then turn off power, disconnect JP1, turn
