(1) Input the PC-98 (400 line) RGB signal.
(2) Set Scan Select to OVERSCAN mode. Adjust either the remote control or VR4002 (DEF SUB PWB) to
vertical height is 100% scan.
(3) Set the remote control H. Width to MAX position and adjust VR9004 (DEF SUB PWB) so that horizontal
width equals 100% scan.
(4) If there is side pincushion distortion, adjust either the remote control or VR5505 (pCOM/V PWB) to
straighten out the right and left vertical lines. Then Adjust VR9004 as outlined in Step (3).
(1) Input the VGA3 (480 line) crosshatch signal to the RGB input.
(2) Set the Scan Select in the UNDERSCAN mode and adjust the remote control or VR4002 of the DEF SUB
PWB so that the vertical height equals 95% scan.
(3) Adjust VR403 (DEF SUB PWB) for Optimum Vertical linearity performance Make sure that the circles are
same size at the top and bottom of the image.
(1) Input the VGA 350 line mode.
(2) Set the Scan Select SW in the UNDERSCAN mode and set the remote control or V. Height to MAX position.
(3) Adjust the VR4002 of the DEF SUB PWB so that the vertical amplitude becomes 100% scan.
(1) Input the VGA 480 line mode.
(2) Press the NORMAL button of the remote control raster control system.
(3) Set the Scan Select SW in the UNDERSCAN mode and adjust the remote control so that the vertical.
(4) Adjust VR5504 of the pCOMA/ PWB so that the video center transverse line becomes straight.
(5) Adjust VR5505 of the pCOMA/ PWB so that the video left transverse line becomes straight.
(6) Adjust VR5401 of the DEF/HV PWB so that the video left transverse line becomes straight.
(1) Input the VGA 480 line mode cress hatch signal.
(2) Set the Scan Select in the UNDERSCAN mode and adjust the remote control so that the vertical height
become 95%±1 %.
(3) Adjust the remote control to vertically center the image.
(4) Adjust VR5501 (pCOM/V PWB) to minimize trapezoidal distortion
(1) Input the VGA 480 line mode crosshatch signal.
(2) Set the Scan Select SW in the mode and adjust the remote control so that the vertical height becomes
95±1 %.
(3) Adjust VR5503 (pCOMA/ PWB) to minimize image tilt.
Upper and Lower blanking sections should be 10±2mm each.
95±1% scan means that there are two black vertical stripes on either side of the image measuring
14±3mm in width. Do not tuch the side pin button.
