D. Saving Adjustment Data

Press “ENTER” to save adjustment data in memory. The character display turns red for approximately one second in this step.

Note: If the circuit adjustment mode is terminated without pressing “ENTER”, changes in adjustment data are not saved.

E. Terminating the Circuit Adjustment Mode

Press the “MENU” button on the remote hand unit twice to terminate the adjustment mode.

Note: The circuit adjustment mode can also be terminated by turning power OFF.

7. Convergence Adjustment Mode

The Convergence mode is used to perform raster geometry correction, and convergence adjustments as specified in Adjustment Procedures 15, 17, 18, 19 and 20.

A. Convergence Mode Activation

1. Press MENU-0-1-5-9

2.When the Convergence Mode is activated, the display at the right appears on a Green Crosshatch.

B. Convergence Mode Functions

In the Convergence Mode there are three main Functions (Categories).

•Pressing “6” activates CONV MISC

•Pressing “5” activates COARSE CONV

•Pressing “4” activates FINE CONV

C. CONV MISC (Press 6)

This mode is used to preset data values controlling the Convergence Generator, and to perform the HV Regulation adjustment.

1.Use the VIDEO button to select an item.

2.Use the ADJUST buttons to change data.

Note: When Item “1 HVOL” is selected the screen goes black except for the data display. This occurs since a black screen is required when making the HV Regulation adjustment.

D. COARSE CONV (Press 5)

There are four Sub Functions in the Coarse mode, COARSE GREEN, COARSE RED, COARSE BLUE and DF.

•COARSE GREEN .... used to make Coarse Raster Geometry Adjustments.

•COARSE RED ... used to make Coarse Red Convergence Adjustments.

•COARSE BLUE ... used to make Coarse Blue Convergence Adjustments.

•DF ... used to preset data values controlling the Dynamic Beam Focus circuit drive signal.
