Adjusting the focus
(1) Adjustment of vertical line (F1-VR adjustment)
Focus Just at the point A (circled) with full green color displayed.
If Core : Halo of the both vertical lines with full red color displayed 1 : 1, adjust to the
less than 1 : 1.
(2) Adjustment of horizontal line (F2-VR adjustment)
Focus Just at the point B (circled, at center of screen) with full white.
(3) If the vertical line is not fully focused, repeat operation (1) and (2) to readjust.
<Adjusting the static focus>
For steps (1) and (2), use the timing No. 12 (106.25kHz/85Hz, 1600 x 1200) H character pat-
tern and crosshatch pattern.
For step (3), use all preset timing H character patterns and crosshatch patterns.
(1) Display a white crosshatch pattern, and adjust the focus according to "2.4.8 Adjusting the
focus".
(2) If the DBF voltage is insufficient or excessive, select DBF H AMP and DBF V AMP from the
OSD, and readjust with the ADJUST button. Then repeat step (1), and adjust so that the
following judgement conditions are satisfied.
(3) For all of the other preset timings, if the DBF voltage is insufficient or excessive, select
DBF H AMP and DBF V AMP from the OSD, and readjust with the ADJUST button.
(4) Make sure that there is no abnormality with the timing No.9 (80kHz/75Hz, 1280 X 1024)
crosshatch (reverse).
