WARNING: BEFORE SERVICING THIS CHASSIS, READ THE “X-RAY RADIATION PRECAUTION”, “SAFETY PRECAUTION” AND “PRODUCT SAFETY NOTICE” INSTRUCTIONS BELOW. X-RAY RADIATION PRECAUTION 1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such hazards, the high voltage must not be above the specified limit. The nominal value of the high voltage of this receiver is (A) kV at zero beam current (minimum brightness) under a 120V AC power source.
SPECIFIC INFORMATIONS GENERAL ADJUSTMENTS WARNING: BEFORE SERVICING THIS CHASSIS, READ THE “X-RAY RADIATION PRECAUTION”, “SAFETY PRECAUTION” AND “PRODUCT SAFETY NOTICE” ON PAGE 3 OF THIS MANUAL. SET-UP ADJUSTMENT ■ The following adjustments should be made when a complete realignment is required or a new picture tube is installed. Perform the adjustments in order as follows : 1. Color Purity 2. Convergence 3. White Balance Note: 1.
4-POLE MAGNETS 6-POLE MAGNETS ■ CENTER CONVERGENCE ADJUSTMENT 1. Display built-in cross-dot pattern using the TEST SIGNAL SELECTION function. 2. Adjust the BRIGHTNESS and CONTRAST Controls for well defined pattern. 3. Loosen the tightening ring and adjust two tabs of the 4-Pole Magnets to change the angle between them (See figure 4.) and superimpose red and blue vertical lines in the center area of the picture screen.
