Adjust to halo condition once, then
adjust to FOCUS JUST.
* Adjust halo to a quarter of core with camera adjustment.
Halo should be a half of core maximum.
The ratio of core : Halo of the vertical lines at both
sides shouled be 1 : 1.

Adjusting ABL
(1) Input the following adjustment timing with the signal generator.
Pattern: Full white (input amplitude = 0.7Vp-p)
Adjustment timing: No.12 (106.25kHz/85Hz, 1600x1200)
(2) Select ABLAJ (ABL) with OSM, and adjust to 115cd/m

+/- 5.
Here, the picture size should follow 2.5.1.10 Adjustment value list.

Adjusting the focus
NOTE) For adjustment of focus with FOCUS VR, be sure to use ISOLATED alignment driver.
<Adjusting the static focus>
For steps (1) and (2), use the timing No. 12 (106.25kHz/85Hz, 1600x1200) H character pattern
and crosshatch pattern.
For step (3), use all preset timing H character patterns and crosshatch patterns.
(1) Display a green or white crosshatch pattern, and adjust the focus according to the proce-
dure mentioned above.
(2) If the DBF voltage is insufficient or excessive, select HFOCS (DBF-H-AMP) from OSM, and
readjust with (-) (+) buttons. Then repeat step (1), and adjust so that the following judge-
ment conditions are satisfied.
(3) For all of the other preset timings, if the DBF voltage is insufficient or excessive, select
HFOCS (DBF-H-AMP) from OSM, and readjust with (-) (+) buttons.
(4) If the focus is unbalanced at right side and left side with other preset timings.
Select HFOCD (DBF-H-PHASE) and readjust with (-) (+) buttons.
(5) If the focus is unbalanced at top and bottom with timing No. 12 (106.25kHz/85Hz, 1600 x 1200),
select DBF2T (DBFV2 TOP) and DBF2B (DBFV2 BOTTOM) and readjust with (-) (+) buttons.
