• 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.

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.

If any Fuse in this TV receiver is blown, replace it

with the FUSE specified in the Replacement

Parts List.

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

parts list in this manual carefully. The use of

substitute replacement parts which do not have the

list may create X-RAY Radiation.
