ADJUSTMENT SET-UP FOR ADJUSTMENT 1. CRT ADJUSTMENT Because the video signal output from a pattern generator is used as 1-1. Precautions the adjustment signal input during adjustment, the video signal (1) Receive the white raster signal, and then perform aging for at output from the pattern generator must conform with the least 20 minutes.
