* After alignment of factory mode, turn off monitor (if you do
not turn off monitor, the OSD menu is always at the factory
mode), then turn on monitor again (at this moment, the
OSD menu goes back to user mode).
TIMER Set OSD display time.

control)
Equipment : 1. Video Test Generator-801GC (Quantum Data)
2. Color-analyzer (Minolta CA-100)
VG2 [(screen), at the bottom of the L.O.T.].
* Apply a video signal in the 1024 x 768 with 68.7 kHz/85 Hz
mode,
select the "full white pattern" (sizes 355 x 265 mm).
* Use color-analyzer (Minolta CA-100) to adjust cutoff and
white uniformity.
OSD R/G/B cut-off and R/G/B gain can be accessed, with
initial data:
9300 K
R cutoff = 30%, R gain = 70% (I C)
G cutoff = 30%, G gain = 70% (I C)
B cutoff = 30%, B gain = 70% (I C)
6500 K
R cutoff = 30%, R gain = 70% (I C)
G cutoff = 30%, G gain = 70% (I C)
B cutoff = 30%, B gain = 70% (I C)
Brightness = 50%, Sub-Contrast = 90%, ABL = 50% (I C)
Step 1: To select the character "FACTORY MODE" as shown
in Fig. 2.1, press "
" to access the OSD menu for
R/G/B gain & cutoff as shown in Fig. 2.2.
Step 2: Press "
" for function selection as shown in Fig 2.3.

RIGHT,
7.1 Connect the video input, set brightness control at 50%
and contrast at minimum position (OSD), Vg2 at Minimum
(counter clockwise, and ABL (OSD) at 50% position.
Slowly increase Vg2 voltage until light output is at
0.1 Ft-L +/- 0.01Ft-L (Y=0.1 Ft-L, on the screen of CA-100).
7.2 (The screen of monitor is dark now)
: Press " " to show the OSD menu as shown in Fig. 2.1.
: Select the character "FACTORY MODE" to access the
R/G/B adjustment as shown in Fig. 2.2 and Fig. 2.3.
: Adjust the cutoff of R/G/B to get 9300K
(x=0.283 +/- 0.015, y=0.297 +/- 0.015), and brightness
output at 0.07 +/- 0.01 Ft-L (Y=0.07Ft-L).
7.3 : Press " " to set contrast at maximum (100%).
: Adjust gain of R/G/B to get 9300K
(x=0.283 +/- 0.015, y=0.297 +/-0.015, don't care about
the Y value)
7.4 Apply a small white square 10 x 10 cm pattern, brightness
set to center (50%), and contrast at maximum (100%),
adjust Sub-contrast control (OSD) to reach 32 +/- 2 Ft-L.
7.5 Apply full white pattern at 9300K, adjust ABL (OSD) to
reach 32+/- 2 Ft-L (contrast at maximum 100%,
brightness at center 50%).
