provided on cabinet back, inside the cabinet, on Before returning any television to the customer,
the chassis or the picture tube. the service technician must be sure that it is
completely safe to operate without danger of
electrical shock.
X-RADIATION PRECAUTION
The primary source of X-RADIATION in 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.
Refer to this service manual high voltage adjustment for specific high voltage limit. If high voltage exceeds
specified limits, take necessary corrective action. Carefully follow the instructions for +Bl volt power supply
adjustment, and high voltage adjustment to maintain the high voltage within the specified limits.
PRODUCT SAFETY NOTICE
Product safety should be considered when acomponent replacement is made in any area of areceiver.
Components indicated by mark ~on the schematic diagram designate components where safety can be of
special significance. It is particularly recommended that only parts designated in the parts list be used for the
replacement of components designated by mark ~.No deviations from resistance wattage or voltage ratings
may be made for replacement items designated by mark
