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 pro-

vided 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 net-

works 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 con-

structed 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 check to maintain the high voltage within the specified limits.

PRODUCT SAFETY NOTICE

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 .
