CRT Focus and H/V Dynamic Focus). This factory-setting does not normally require readjustment. The FOCUS ENABLE box in the PREFERENCES MENU may now be unchecked to prevent accidental defocusing.

4.4. CRT Focus and H/V Dynamic Focus

The CRT and H/V Focus adjustments are factory-setand do not normally require adjustment. They should be performed together in a back-and-forth manner to achieve the best possible overall focus.

To perform the CRT Focus:

1.From the FACTORY ADJUSTMENTS MENU, select CRT FOCUS.

2.Select G on the remote.

3.Select the STANDARD CROSSHATCH test pattern.

4.Use the up/down arrow keys to obtain the best possible focus in both the

center of the screen and in the overall test pattern.

5.Repeat the above steps for R and B.

To perform the H/V Dynamic Focus:

1.From the FACTORY ADJUSTMENTS MENU, select H/V DYNAMIC FOCUS.

2.Continue with the STANDARD CROSSHATCH test pattern from above.

NOTE: The H/V Dynamic focus is performed on all three (3) colors together and the colors are not individually selectable.

3.Use the up/down arrow keys to achieve the best possible focus at the edges of the screen.

4.Repeat the CRT Focusing from above, then repeat the H/V Dynamic Focus again. Several iterations may be needed to achieve the best possible overall screen focus.

4.5.ILA® Sensitivity and Bias

ILA® Sensitivity and Bias are preset for the factory-set sources and will not normally require adjustment. Readjustments may be required due to variations between the factory and the field environments. When new sources are set up, ILA® Sensitivity and Bias must be set (or copied from another source and touched-up) for each new source.

The ILA® Sensitivity and Bias can be adjusted for any color. It is preferable to start with Blue since Blue is a weaker color to observe than Red or Green. The ILA® Sensitivity is the ILA® biasing frequency that affects the resolution and brightness on the screen. The ILA® bias settings adjust the electrical bias levels to each ILA® assembly to a “just off” threshold point. The smallest incoming light from the CRT will cause the ILA® assembly to react. When properly set, this adjustment will put each ILA® assembly at the threshold of operation. If set incorrectly, the black level will be adversely affected and the ILA® assembly will not react properly to incoming light. Perform all ILA® Bias adjustments in a darkened room.
