15. When the upper left corner is converged satisfactor ily, pr ess ENTER to return

to the MOVE/SIZE MODE.Toggle the MODE KEY to the MOVE MODE. Refer to

Figure 4.0-12 on page 4-26 and center the cursor over each of the positions

in the sequence shown, wherever convergence is required, repeating the

MOVE/SIZE/ADJUSTMENT steps for each area that needs convergence.

16. When finished using full screen cursor, press ENTER and togg le the MODE

KEY to the SIZE MODE.

17. Use the arrow keys to size down to a cursor of approximately ¼ screen size.

18. Select the areas to be converged and converge the entire screen in the

sequence shown in Figure 4.0-13 on page 4-26. Start at the upper left

corner and continue in the same manner as performed with the full screen

cursor in Step 15.

19. Save changes when finished with XY Registration.

4.7. Black Level (G2) and Sensitivity Offset

G2 sets the threshold of the CRT image and is adjusted, along with the Sensitivity

Offset adjustment, using the Grey/Pluge test pattern. Together, these

adjustments determine the level of the darkest and brightest areas of the video

image.

The G2 adjustment is preset at the factory and may need little or no adjustment.

These adjustments are made in sequence, one (1) color at a time. It is preferable

to start with Blue because it is the weakest color of the three (3) to observe.

When the Blue settings are complete, the same adjustments are performed f or

Green and Red.

4.7.1. Black Level (G2)

To set the Black Level for Blue:

1. Use the RGB and HIDE KEYS to hide R and G. Verify that the

SHUTTERS ON HIDE box under the SYSTEMS-PREFERENCES MENU is

checked.

2. Toggle the RGB KEY to select B only.

CAUTION!!! Ensure that only the color to be adjusted is

highlighted. Otherwise all colors are reset and good data from a previous

setup will be deleted.

3. Access CONVERGENCE MENU and select RESET.

4. Access the Grey/Pluge test pattern.

5. Access BLACK LEVEL (G2), from the CONVERGENCE MENU.

6. Use the up/down arrow keys to adjust the black level so the small,

black square in the center of the larger black square is just barely

visible (as illustrated in Figure 4.0-17). Press ENTER when finished.
