• Safety Instruction
WARNING: Only competent service personnel may carry out work involving the testing or repair of
this equipment.
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 26
at max beam
current. The high voltage must not, under any
circumstances, exceed 29.5
(25"), 30 (28").
Each time a receiver requires servicing, the high
voltage should be checked. 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 continued X-RAY
RADIATION protection,the replacement tube
must be exactly the same type tube as specified
in the parts list.
1. Potentials of high voltage are present when this
receiver is operating. Operation of the receiver
outside the cabinet or with the back board
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) 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.
2. If any Fuse in this TV receiver is blown, replace it
with the FUSE specified in the Replacement
Parts 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 under AC230 volts,
50Hz. NEVER connect to DC supply or any other
power or frequency.
Many electrical and mechanical parts in this 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 supplements,
electrical components having such features are identified by designated symbol on the parts list.
Before replacing any of these components, read the
par ts list in this manual carefully. The use of
substitute replacement parts which do not have the
list may create X-RAY Radiation.
