Drive Adjustment :
2-3. Using the volume keys on the jig remote controller, bring the figure of 4. G DRIVE up to more than 200 till the color becomes
greenish.
2-4. Reduce the numeric figure to the point where the greenish color disappears completely.
2-5. Use the volume keys on the jig remote controller to increase the numeric figure of 5. B DRIVE up to more than 200 till the color
becomes bluish.
2-6. Reduce the numeric figure to the point where the bluish color disappears completely.
2-7. Repeat the process of 2-1 to 2-6 for several times and adjust for whiter look.
Focus Adjustment :
Input signal : Dot pattern
Adjustment point : SFR located at upper part of FBT (T601)
Measuring instrument : Pattern generator
• Adjust SFR which is located at upper part of FBT (T601) in order to get the best focus point for the
dot.
3. Screen Adjustment :
Input signal : No signal (No raster)
Adjustment point : SFR located at lower part of FBT (T601)
Measuring instrument: Pattern generator / Leader : LCG-404
1. Enter to the "Adjustment Menu Screen" by using the jig remote controller.
2. Press "0" key of the 10 numeric channel keypad to get a horizontal single line screen.
(Fig. 2-2)
3. Adjust SFR located at the lower part of FBT (T601) until the horizontal line starts to be
slightly brightened.
4. Repeat the process of step 2 and return to the "Adjustment Menu Screen".
