2. In the LOW mode of W/B, adjust the GAIN R for +15 higher than the value in the HIGH mode, adjust the GAIN G for _25 lower than the value in the HIGH mode and adjust GAIN B that is the same as the value in the HIGH mode.

3. Measure the chromaticity (x, y).

4. Input the 30 IRE flat field signal.

5. Adjust the BIAS R and BIAS B in the LOW mode of W/B until the chromaticity (x, y) that is measured at step 3 is obtained.

6. Input the 80 IRE flat field signal.

7. Adjust the GAIN R and GAIN B in the LOW mode of W/B until the chromaticity (x, y) that is measured at step 3 is obtained.

8. Repeat steps 4 to 7 until the chromaticity (x ± 0.002, y ± 0.004) with reference to the chromaticity (x, y) that is measured at step 3 is obtained.

9. Press the MEMORY key and save the adjustment value.

2-5-3. HIGH Mode of VIDEO

2-5-1. HIGH Mode of INPUT-A

Connect the10-step signal to the INPUT-A connector and measure the chromaticities at each brightness.

If chromaticities are different at each brightness, perform the following adjustment.

1. Input the 100 IRE flat field signal to the INPUT-A connector.

2. Measure the chromaticity (x, y).

3. Input the 80 IRE flat field signal.

4. Adjust the GAIN R and GAIN B in the HIGH mode of W/B until the chromaticity (x, y) that is measured at step 2 is obtained.

5. Input the 30 IRE flat field signal.

6. Adjust the BIAS R and BIAS B in the HIGH mode of W/B until the chromaticity (x, y) that is measured at step 2 is obtained.

7. Repeat steps 3 to 6 until the chromaticity (x ± 0.002, y ±0.004) with reference to the chromaticity (x, y) that is measured at step 2 is obtained.

8. Press the MEMORY key for saving the adjustment value.

1. Input the 80 IRE flat field signal to the INPUT-A connector.

1. Input the NTSC or PAL video signal to the input connector.

2. In the HIGH mode of W/B, adjust the GAIN R for _20 lower than the value in the INPUT-A HIGH mode, adjust the GAIN G for —35 lower than the value in the INPUT-A HIGH mode and adjust GAIN B that is the —20 lower than the value in the INPUT-A HIGH mode.

3. Adjust BIAS G for —5 lower than the value in the INPUT-A HIGH mode, adjust the BIAS R and BIAS B for the same value as those of the INPUT-A HIGH mode.

4. Press the MEMORY key and save the adjustment value.

2-5-4. LOW Mode of VIDEO

1. Input the NTSC or PAL video signal to the input connector.

2. In the LOW mode of W/B, adjust the GAIN R for —20 lower than the value in the INPUT-A LOW mode, adjust the GAIN G for —35 lower than the value in the INPUT-A LOW mode and adjust GAIN B that is the —20 lower than the value in the INPUT-A LOW mode.

3. Adjust BIAS G for —5 lower than the value in the INPUT-A LOW mode, adjust the BIAS R and BIAS B for the same value as those of the INPUT-A HIGH mode.

4. Press the MEMORY key for saving the adjustment value.
