CAUTION
: Before servicing the chassis, read the "Safely Precaution".
"X -Ray radiation Precaution" and "Product Safety Notice" on Page 2 of
this manual.
X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To
Avoid such hazards the high voltage must not be specified limit. The normal value of
the high voltage of this receiver is App. 28.5KV at zero beam current (minimum
brightness) under 230V AC power source. The high voltage must not under any
circumstances exceed 30KV.
2. Each time a receiver requires servicing the high voltage should be checked following
the HIGH VOLTAGE CHECK procedure in this manual. It is recommended the
reading of the high voltage be recorded as a part of the service record. It is
important to use an accurate and reliable high voltage meter.

- Page 2 3. The primary 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 used in this TV receiver. 4. Some parts in this receiver have special safety-related characteristics for X-RAY RADIATION protection.
- Page 3 Make sure the AC power supply is 230V, 50Hz. Switch on the TV receiver, tune in an active channel. Measure the voltage between C641 on Main P.C. Board DC voltmeter. Set contrast, brightness, color to maximum. Adjust VR631 on Main P. C. Board for B+140V+/-0.5V voltage reading. HIGH VOLTAGE CHECK AUTION: There is no high voltage adjustment in this chassis, B+140V voltage directly relates to the high voltage.
