limit. The normal value of the high voltage of this receiver is 26.5KV +/-
2KV under 230V AC power source. The high voltage must not exceed
29KV.
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.
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
