Technical information

2.2.2.3.3 Preliminary Set-Up

Proceed as follows.

1. Insert the IBM Personal System/2 Color Displays Test-Pattern Diskette

in drive A of the system unit.

CAUTION:

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

high voltages on the Yoke, analog, and video cards.

2. Check to make sure that the G2 potentiometer is turned fully counter

clockwise (CCW).

3. Power on the system unit and the 8513 Display. The system unit runs

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

4. With the Brightness control set to the center detent position

(midpoint), adjust G2 and focus until the setup menu or an

informational prompt is visible on the screen. From the setup menu

select pattern C and adjust G2 to give minimum background

illumination.

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

adjustments.

6. Set the contract control to midpoint.
