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 resistor-

capacitor 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 !.
