Deflection Adjustment
1) NTSC mode should be adjusted after adjusting PAL mode. 2) PAL adjustment should be done in the EU CH05,and NTSC adjustment should be done in the CH13 or Multi 48CH. Note, RE/RL Model(without NTSC-M system) receive CH13 in the V-3 input. 3) Press the button of Remote Controller for adjustment to reset the convergence Adjustment Mode : Press the IN_START key Data reset : Press the 0 key. Saving and returning Adjustment mode : Press the ENTER Key Note. Refer adjustment items to Appendix1.

2. Adjustment
1) Operate adjustment about Red,Green,Blue centering magnet. 2) SGS-THOMSON Convergence assy Adjust until the center of blue signal is shifted up to 40mm left from that of green signal and center of red signal is shifted up to 40mm right from that of green signal with turning the centering magnet. 3) After adjustment, re-adjust convergence data and exit the adjusting mode. a.Adjustment mode:Press the IN_START key. b.Data reset : Press 0 KEY. c.Adjustment mode cancellation : Press the Enter key.

2. PAL Mode Deflection adjustment
Do not adjust H-POS,V-POS, V-LIN, S-COR, A-BOW, A-ANG, UCPIN, LCPIN, V-ASP,V-SCR in PAL mode. Select the below each mode using CHD, E and adjust using VOLF, G on the remote controller. At SVC mode, press the �0� key get into the deflection adjustment mode. 1) H-POS (Horizontal Position Adjustment) Adjust so that the horizontal center line of screen is in accord with the geometric horizontal center line of screen JIG. 2) V-POS (Vertical Position Adjustment) Adjust so that the vertical center line of picture is in accord with the vertical center line of the screen. 3) HSIZE (Horizontal SIZE Adjustment) Adjust so that the outermost left and right vertical line of the screen is accord with the last point of the frame 4) VSIZE (Vertical SIZE Adjustment) Adjust until Sixth vertical center line from upper and lower center of the picture is accord with the last point of the frame. 5) U-VL (Upper Vertical Linearity Adjustment) Adjust the vertical interval of screen upper. 6) L-VL (Lower Vertical Linearity Adjustment) Adjust the vertical interval of screen lower.
