Excessive high voltage can prodece potentially hazardous X-RAY RADIATION. To avoid such hazards, the high voltage must not exceed the specified limit. The nominal value of the high voltage of this receiver is 29-31kv at max beam current. The high voltage must not, under any circumstances, exceed 35kv. (33kv : SAMSUNG CRT) Each time a receiver require servicing, the high voltage should be checked. It is imprortant to use an accurate and reliable high voltage meter. 2. The only 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 specified in the parts list. SAFETY PRECAUTION 1. Potentials of high voltage are present when this receiver is operating. Operation of the receiver outside the cabinet or with the back board removed involves a shock hazard from the receiver. 1) Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on high-voltage equipment. 2) Dischange the high potential of the picture tube before handling the tube. The picture tube is highly evacuated and if broken, glass fragments will be violently expelled. 2. If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement Parts List. 3. When replacing a high wattage
