WARNING :BEFORE SERVICING THIS CHASSIS,
READ THE X-RAY RADIATION
PRECAUTION , SAFETY
PRECAUTION AND PRODUCTION
SAFETY NOTICE BELOW.
X-RAY RADIATION PRECAUTION
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 highvoltage of this
receiver is 23-25KV(14 ), 25~29KV(21 ) at max.
beam current, The high voltage must not,under
any circumstances, exceed 26KV(14 ),
31KV(21 ).
Each time a receiver requires servicing,the high
voltage should be checked.
It is recommended the reading of the high
voltage be 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 X-
RAY RADIATION protection, the replacement
tube must be exactly the same type tube as
specified in the parts list.
SAFETY PRECAUTION
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 necesary when working on high
voltage equipment.
2) Always discharge 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 receiveris blown, replace it
with the FUSE specified in the Replacement
Parts list.
3. When replacing a high wattage resistor (metal
oxide 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 AC260 volts,
50Hz. NEVER connect to DC supply or any other
power or frequency.
PRODUCT SAFETY NOTICE
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
parts list in this manual carefully.
The use of substitute replacement parts which do
not have the same safety characteristics as
specified in the parts list may create X-RAY
Radiation.
