10. ADIATION To avoid such hazards the high voltage must not exceed the specified limit The nominal value of the high voltage of this receiver is 25 6KV Normal Type 27 9KV Flat Type at max beam current The high voltage must not under any circumstances exceed 28 6KV Normal Type 30 9KV Flat Type Each time a receiver requires servicing the high voltage should be checked It is important 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 cover 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 Always discharge the picture tube to avoid the shock harzard before removing the anode cap 3 Discharge 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 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 resistor metal oxide film resistor
