„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.
