Safety Instruction
NOTE
BEFORE 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 hazardous X-RAY RADIATION. To avoid such hazards, the
high voltage must not exceed the specified limit. The
nominal value of the high voltage of this receiver is
29kV(29”) at max beam current. The high voltage must
not, under any circumstances, exceed 30.5kV(29”).
Each time a receiver requires servicing, the high voltage should be checked. It is recommended the reading
SAFETY PRECAUTIONS
1. Potentials of high voltage are present when this
receiver is operating. Operation of the receiver outside
the cabinet or with the back cover removed involves a
shock hazard from the receiver.
1) Servicing should not be attempted by anyone who is
not thoroughly familiar with the precautions necessary
when working on high voltage equipment.
2) Always discharge the picture tube to avoid the shock
harzard before removing the anode cap.
3) Discharge the high potential of the picture tube before
handling the tube. The picture tube is highly evacuated
and if broken, glass fragments will be violently expelled.
of the high voltage recorded as a part of the service
recorded as a part of the service records. It is important
to use an accurate and reliable high voltage meter.
2. The only source of X-RAY RADIATION in this TV
receiver is the picture tube. For continuous RADIATION
protection, the replacement tube must be exactly the
same type tube as specified in the “PART LIST”.
2. If any FUSE in this TV receiver is blown, replace it will
the FUSE specified in the “PART LIST”.
3. When replacing a high wattage resistor (oxide metal
film resistor) in circuit board, keep the resistor 10mm
away from circuit board.
4. Keep wires away from high voltage or high temperature
components.
5. This receiver must operate between AC100~240 volts,
50/60Hz. NEVER connect to DC supply or any other
power or frequency.
PRODUCT SAFETY
Many electrical and mechanical parts in this chassis have
special safety-related characteristics.
These characteristics are often passed unnoticed by a
visual inspection and the X-RAY RADIATION protection
afforded by them cannot necessarily be obtained by using
replacement components rated for higher voltage, wattage,
etc.
Replacement parts which have these special safety characteristics are identified in this manual and its supple-
ments, electrical components having such features are
identified by designated symbol on the “PART LIST”.
Before replacing any of these components, read the “PART
LIST” in this manual carefully.
The use of substitute replacement part which do not have
the same safety characteristics as specified in the “PART
LIST” may created X-RAY RADIATION.
