SAFETY INSTRUCTIONS
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "X-RAY RADIATION PRECAUTION","SAFETY PRECAUTION" AND "PRODUCT 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 high voltage of this receiver is 25.5 (21":26.5 ) at max beam current. The high voltage must not, under any circumstances, exceed 27.5 (21":29.0 ). Each time a receiver requires servcing, the high voltage should be checked following the HIGH VOLTAGE CHECK procedure on page 9 of this manual. 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 continued X-RAY RADIATION protection,the replacement tube must be exactly the same type tube as speci�ed 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 necessary when working on highvoltage 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 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 circut 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.
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 speci�ed in the parts list may create X-RAY Radiation.
