A computer with : - Apply a video signal in the 640 x 480 with 31.5 kHz/60 Hz mode. - Select the "crosshatch" pattern. Adjust trimming pot-meter 3540 - "ATI VGA1024" interface card until the DC voltmeter reads : 67.5 +/- 0.2V (for PHILIPS CRT), - PGA1024 (4822 212 30916) But 68 V for CPT CRT - PGA1280 (4822 212 30917) 3.
