SAFETY INSTRUCTION
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 hazard
ous 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"),25-28KV(20") at max. beam current. The
 high voltage must not,under any circumstances, 
 exceed 26KV (14"),30KV (20").  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 
briken, 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,  watt-
age,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.
