SAFETY INSTRUCTIONCAUTION

NOTEBEFORE SERVICING THIS CHASSIS READ THE X-RAY RADIATION PRECAUTIONS,SAFETY PRECAUTIONS AND PRODUCT SAFETY NOTICE BELOW.

X-RAY RADIATION PRECAUTIONS

1. Excessive high voltage can produce potentially hazard-ous X-RAY RADIATION. To avoid such hazards, thehigh voltage must not exceed the specified limit. Thenominal value of the high voltage of this receiver is25kV(21) at max beam current. The high voltage mustnot, under any circumstances, exceed 27kV(21).Each time a receiver requires servicing, the high volt-age should be checked. It is recommended the reading

SAFETY PRECAUTIONS

1. Potentials of high voltage are present when thisreceiver is operating. Operation of the receiver outsidethe cabinet or with the back cover removed involves ashock hazard from the receiver.

1) Servicing should not be attempted by anyone who isnot thoroughly familiar with the precautions necessarywhen working on high voltage equipment.

2) Always discharge the picture tube to avoid the shockharzard before removing the anode cap.

3) Discharge the high potential of the picture tube beforehandling the tube. The picture tube is highly evacuatedand if broken, glass fragments will be violently expelled.

PRODUCT SAFETY

Many electrical and mechanical parts in this chassis havespecial safety-related characteristics.These characteristics are often passed unnoticed by avisual inspection and the X-RAY RADIATION protectionafforded by them cannot necessarily be obtained by usingreplacement components rated for higher voltage, wattage,etc.Replacement parts which have these special safety char-acteristics are identified in this manual and its supple-

ments, electrical components having such features areidentified by designated symbol on the PART LIST.Before replacing any of these components, read the PARTLIST in this manual carefully.The use of substitute replacement part which do not havethe same safety characteristics as specified in the PARTLIST may created X-RAY RADIATION.

of the high voltage recorded as a part of the servicerecorded as a part of the service records. It is importantto use an accurate and reliable high voltage meter.

2. The only source of X-RAY RADIATION in this TVreceiver is the picture tube. For continuous RADIATIONprotection, the replacement tube must be exactly thesame type tube as specified in the PART LIST.

2. If any FUSE in this TV receiver is blown, replace it willthe FUSE specified in the PART LIST.

3. When replacing a high wattage resistor (oxide metalfilm resistor) in circuit board, keep the resistor 10mmaway from circuit board.

4. Keep wires away from high voltage or high temperaturecomponents.

5. This receiver must operate between AC 100~240 volts,50/60Hz. NEVER connect to DC supply or any otherpower or frequency.

PIN NAME FUNCTION INTERFACE1 IF VCC A Vcc terminal for the IF circuit.

Supply 5V.2 RIPPLE A terminal should be connected to an internal

FILTER bias filler. Put a capacilor.
