2.5.2.4.6 Procedure Using a Color Analyzer 

  The use of a color analyzer is recommended, if available, for setting color points and brightness.

  All adjustments must be made with the brightness control set at center detent. Select mode 4 (or mode 3 if not available) to display the test patterns.

1. Select option 3, pattern C (Full Screen Raster), and press spacebar to get a black screen.
   a.  Set RV014 (R.BKG) and RV034 (B.BKG) fully clockwise.
   b.  Adjust RV508 (G2) until a background raster is just visible.
   c.  Adjust RV014 (R.BKG) until raster has a red tinge, readjust until red tinge just disappears.
   d.  Adjust RV034 (B.BKG) until raster has a blue tinge, readjust until blue tinge just disappears.
   e.  Adjust RV508 until background raster just disappears. When background color point is set correctly, the raster is white or gray until it disappears.  If it is not, repeat this step.

2. Check that the contrast control is set to max and the brightness control is at center detent.

3. Press PF3 to return to the setup patterns.  Select option 2, pattern B (50 mm square block).

4. Press spacebar to get a white block.

5.  Adjust three drive potentiometers (RV011, RV021, and RV031) for correct white color point.

  Using a color analyzer, in accordance with the manufacturer's instructions, this is:
        x=0.297 ± 0.01
        y=0.320 ± 0.01.

6.  Set RV102 (SUB CONT), using the color analyzer to give:
      (8517) 150 cd/m².
      (9517) 130 cd/m².

7.  Set contrast control to minimum (CCW). Readjust RV014 and RV034 for correct color point.

8.  Repeat steps 2 to 7, until color point is maintained at min and max settings of contrast control.

9.  Press PF3 to return to setup patterns. Select option 4, pattern D (Gray Scale). Set contrast control to max.

10. Check that all levels of scale are visible.  If a background raster is visible, adjust G2 until background raster just disappears.

11. After adjusting G2 reset the color point, steps 2 to 10.

12. Do focus and convergence adjustments after this procedure.
