2.5.2.4.3 Preliminary Steps

Proceed as follows.

1. Insert the 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 analog and video cards.

2. Turn power on at the system unit and the display. The system unit

runs its internal checks, and then loads the program from the

diskette.

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

adjustments.

Mode Selection: The mode for setting up the display is determined by the

modes supported by the display adapter cards.
