Adjustment.pdfADJUSTMENT GENERAL INFORMATION All adjustment are thoroughly checked and corrected when the monitor leaves the factory, but sometimes several adjustments may be required. Adjustment should be following procedure and after warming up for a minimum of 30 minutes. Alignment appliances and tools. - IBM compatible PC. - Programmable Signal Generator. (eg. VG-819 made by Astrodesign Co.) - EPROM or EEPROM with saved each mode data. - Alignment Adaptor and Software. - Digital Voltmeter. - White Balance Meter. - Luminance Meter. - High-voltage Meter. AUTOMATIC AND MANUAL DEGAUSSING The degaussing coil is mounted around the CDT so that automatic degaussing when turn on the monitor. But a monitor is moved or faced in a different direction, become poor color purity cause of CDT magnetized, then press DEGAUSS on the OSD menu. 7) DIST. ADJ. BALANCE command. 8) Adjust balance of side-pincushion as arrow keys to be the best condition. 9) DIST. ADJ. BALANCE command. 10) Adjust parallelogram as ar
