SAFETY NOTICE
SAFETY PRECAUTIONS
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 resistorcapacitor network 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.
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 must be
maintained within the specified limits.
PRODUCT SAFETY NOTICE
Product safety should be considered when a component replacement 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 designed 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 !.
