"X -Ray radiation Precaution" and "Product Safety Notice" on Page 2 of this manual. 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 specified limit. The normal value of the high voltage of this receiver is App. 28.5KV at zero beam current (minimum brightness) under 230V AC power source. The high voltage must not under any circumstances exceed 30KV. 2. Each time a receiver requires servicing the high voltage should be checked following the HIGH VOLTAGE CHECK procedure in this manual. It is recommended the reading of the high voltage be recorded as a part of the service record. It is important to use an accurate and reliable high voltage meter. 3. The primary source of X -RAY RADIATION in this TV receiver is the picture tube. For continued X-RAY RADIATION protection, the replacement tube must be exactly the same type tube as used in this TV receiver. 4. Some parts in this receiver have special safety-related characteristics for X-RAY RADIATION protection. For continued safety, parts replacement should be undertaken only after referring the PRODUCT SAFETY NOTICE below. SAFETY PRECAUTION WARNING: Service should not be attempted by anyone unfamiliar with the necessary Precautions on this receiver. The following are the necessary precautions to be observed before servicing this chassis. 1. Since the power supply circuit of this receiver is directly connected to the AC power line. An isolation transformer should be used during any dynamic service to avoid possible shock hazard. 2. Always discharge the picture tube anode to the CRT conductive coating before handling the picture tube. The picture tube is highly evacuated and if broken, glass fragments will be violently expelled. Use shatterproof goggles and keep picture tube away from the unprotected body while handling. 3. When replacing a chassis in the cabinet, always be certain that all the protective devices are put back in place, such as: nonmetallic control; knobs, insulating covers, shields, isolation resistor-capacitor, network, etc. 4. When replacing parts or circuit boards, disconnect the power cord. 5. When replacing a high voltage resistor (metal oxide resistor) on circuit hoard, keep the resistor 10mm(1/2 in.) away from circuit board. 6. Connection wires must be kept away from components with high voltage or high temperature. 7. If any fuse in this TV receiver is blown, replace it wi
