Proceed as follows.

1. Insert the IBM PS/2 Color Displays Test-Pattern Diskette into drive A

of the system unit.

CAUTION:

Use caution when making adjustments with the cover removed. There are

high voltages on the analog and video cards.

2. Power on the system unit and the display. The system unit runs its

internal checks, and then loads the program from the diskette.

3. With the Brightness control set to center detent (midpoint), adjust G2

and Focus until the setup menu is visible. Select pattern C and

adjust the G2 control to give minimum background illumination.

4. Allow 20 minutes for the display to warm up before making any further

adjustments.

5. Set the Contrast control to midpoint.

Note: On 6318 Displays center the four POTS on the Operator Control Card

prior to performing the Geometry Adjustments.
