2. SAFETY INSTRUCTION
NOTE BEFORE SERVICING THIS CHASSIS READ THE "X-RAY RADIATION PRECAUTIONS", "SAFETY PRECAUTIONS" AND "PRODUCT SAFETY NOTICE" BELOW. X-RAY RADIATION PRECAUTIONS 1. Excessive high voltage can produce 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 25kV(21") at max beam current. The high voltage must not, under any circumstances, exceed 27kV(21"). Each time a receiver requires servicing, the high volt-age should be checked. It is recommended the reading SAFETY PRECAUTIONS 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. |
