„PREPARATION

(1)When the reverse shading function is used, open Menu [DDIC] [FPGA], and set [Left side Right] and [Up Side Down] to [Off].

(2)Open Menu [Area Shading] and, after clicking [LUM]. Set each [R], [G] and [B] to [Default] respectively, then click [Transmit].

(3)Click [DYN] or [STC] and set [R], [G] and [B] to [Default] respectively in the same way, then click [Transmit].

„SHADING ADJUSTMENT

(1)Open Menu [DDIC] [FPGA], and set [R Mute], [G Mute] and [B Mute] to [On].

(2)Set [R], [G] and [B] Flat Field level to 204, respectively.

(3)Open Menu [Area Shading] and click [STC]. Then adjust the screen with the slide bar for adjustment level setting so that the screen is evenly colored.

(4)Open Menu [DDIC] [Flat Field] and set [R], [G] and [B] Flat Field level to 614, respectively.

(5)Open Menu [Area Shading] and click [DYN]. Then adjust the screen with the slide bar for adjustment level setting so that the screen is evenly colored.

(6)Open Menu [DDIC], and set [DYNDAT] [STCDAT] to [Off].

(7)Open Menu [Flat Field] and set [R] Flat Field level to 204,

[G]and [B] Flat Field level to 0, respectively. Record the brightness of the screen at this time

(8)Set [R] Flat Field to 614 and record the brightness of the screen at this time.

(9)Return [DYNDAT] and [STCDAT] to [On].

(10)Open Menu [EVR] and adjust [R OFFSET] so that the brightness of the screen become the same value as those of the recorded value.

(11)Open Menu [DDIC] [Gain/Setup] and click [Gain]. Adjust [DDIC] [GAIN] so that the brightness of the screen at the

[R]Flat Field level of 614 become the same value re- corded in 8) above.

(12)In the same manner as for the above steps, also adjust

[G]and [B] Flat Field level.

(13)Adjust [LUM], if necessary. Keep the Flat Field level at 1023 at the center of the screen as much as you can.

(14)After adjustment, transfer the data to the reverse shad- ing adjustment memory by clicking [Copy Shading Data to Reverse Shading Data] on the bottom of the Area Shading screen. At this time, open [Shading] on [Config- uration] tool bar and set the values according to the table on the right side so as to compensate the vertical reverse shading gradient.

∗If necessary, adjust Up Side Down position. When adjusting the Up Side Down position, hang the unit from the ceiling. Open Menu [DDIC] [FPGA] and set [Left Side Right] and [Up Side Down] to [On]. For the adjustment, follow the same man- ner as for the steps (1)~(14) above.
