SAFETY PRECAUTION
X-RADIATION PRECAUTION
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.
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 +B1 volt power supply
adjustment, and high voltage adjustment to maintain the high voltage within the specified limits.
PRODUCT SAFETY NOTICE
SPECIFICATIONS
Product safety should be considered when a component replacement is made in any area of a receiver.
Components indicated by mark
in the parts list and the schematic diagram designate components in which
safety can be of special significance. It is particularly recommended that only parts designated on the parts list in
this manual be used for component replacement designated by mark
. No deviations from resistance wattage
or voltage ratings may be made for replacement items designated by mark
.

!
1: An isolation transformer should be connected in the
power line between the receiver and the AC line
when a service is performed on the primary of the
converter transformer of the set.
2: Comply with all caution and safety-related notes
provided on the cabinet back, inside the cabinet, on
the chassis or the picture tube.
3: When replacing a chassis in the cabinet, always be
certain that all the protective devices are installed
properly, such as, control knobs, adjustment covers
or shields, barriers, isolation resistor-capacitor networks
etc. Before returning any television to the customer,
the service technician must be sure that it is completely
safe to operate without danger of electrical shock.
