3. Precaution against X-Rays

The primary source of X-RADIATION in the television receiver is the picture tube. The picture tube is specially
constructed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube
must be the same type as the original including suffix letter. Excessive high voltage may produce potentially
hazardous X-RADIATION. To avoid such hazards, the high voltage must be maintained within specified limit. If
high voltage exceeds specified limits, take necessary corrective action. Follow the instructions carefully for +B1
volt power supply adjustment, and high voltage adjustment to maintain the high voltage within the specified
limits.
