(5)Select the color to adjust by pressing “3” key on the remote controller.

(6)Confirm that the cursor is in the movable status (the cursor blinking status).

(7)Select the adjusting position by pressing “8”, “4” and “6”.

(8)When the adjusting position is determined, press “5” key on the remote controller to enter the cursor blink- ing status.

(9)Set the cursor to the adjusting position by pressing “2”, “8”, “4” and “6”, and perform the pattern distortion correction and color matching adjustments.

(10)Press “5” key again and move the cursor. Perform the adjustment in the same way as described above.

(11)After the adjustment completes, perform the automatic storing operation by pressing “7” key.

(12)In the same way as described above, adjust WIDE 1, WIDE 2 and WIDE 3 screens using PIC-SIZE key.

(13)When all of the screen mode adjustment complete, perform the automatic storing operation by pressing “7” key.
