    SAFETY INSTRUCTION Before servicing and aligning this equipment, please read the following “X-RAY RADIATION PRECAUTION” ,“SAFETY PRECAUTION” and “PRODUCT SAFETY NOTICE”. 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 normal value of the high voltage of this receiver is 26.5kV(20”) at zero beam current (minimum brightness) under 220V AC power source.

  • Page 4: Product Safety Notice

    8) Before returning the set to your customer, always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminals, screwheads, metal overlays, control shafts etc. to be sure the set is safe to operate without danger of electrical shock. Plug the AC line cord directly into a 220V AC outlet (do not use a line isolation transformer during this check).

    3) Connect the power plug to AC 220V/50Hz, turn on the power switch, wait for normal raster, Check B 110V±0.2V. Test point B1-5V B2-8V B3-10V B4-32V TH-12V TH-20V TH-200V DC(V) 20(22) INSTALLATION AND SERVICE ADJUSTMENTS GENERAL In the majority of cases, a color television receiver will need only slight touch – up adjustment upon installation.

    8. Check the purity of the red and blue raster. 9. Obtain a white raster, referring to “CRT WHITE BALANCE ADJUSTMENT”. 10. Proceed with convergence adjustment. FIG.3 CONVERGENCE ADJUSTMENT NOTE: Before attempting any convergence adjustments, the receiver should be operated for at least fifteen minutes.
